The error TypeError: Cannot read properties of undefined (reading 'SelectionDirection') suggests there might be an issue with how the Vim mode is being initialized or with the timing of the initialization. The code you provided looks mostly correct, but there may be a few areas where the integration with vim-monaco can be improved.

Steps to Simplify the Implementation:

  1. Ensure Proper Import and Initialization: Make sure that vim-monaco is correctly imported and that the editor is fully initialized before any Vim mode operations.

  2. Initialization Timing: Sometimes, the issue arises because the Vim mode is being initialized before the editor is fully ready. Using setTimeout can help, but it's not always the best approach. Instead, you can use the monaco.editor.onDidCreateEditor event to ensure the editor is fully created before initializing Vim mode.

  3. Status Bar: The JSFiddle example uses a status bar for Vim mode. Make sure you include it in your React component.

Here's an updated version of your MonacoEditor.tsx component with these considerations:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useImperativeHandle(ref, () => ({
    focus: () => {
      monacoEditorRef.current?.focus();
    },
    getValue: () => {
      return monacoEditorRef.current?.getValue();
    },
  }));

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      // Ensure the editor is fully initialized before enabling Vim mode
      editor.onDidCreateEditor(() => {
        try {
          const vimMode = new VimMode(editor);
          vimModeRef.current = vimMode;

          // Define Vim commands
          vimMode.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
          });

          vimMode.defineEx('q', '', () => {
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });

          vimMode.defineEx('wq', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });

        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }
      });

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
});

export default MonacoEditor;

Additional Notes

  • Status Bar: Make sure you have a div for the Vim status bar. It's important for the Vim mode to show its current status.
  • CSS: Ensure your MonacoEditor.css file includes styles for the editor container and Vim status bar.

If you continue to face issues, inspect the adapter.ts file in the vim-monaco library to understand where SelectionDirection is being accessed and ensure that the editor is fully ready before Vim mode initialization.

The error indicates that onDidCreateEditor is not a valid method on monaco.editor.IStandaloneCodeEditor. This method doesn't exist in the Monaco Editor API.

Instead, you can use setTimeout to delay the initialization of Vim mode to ensure the editor is fully loaded. Here's an updated version of your MonacoEditor.tsx component:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;
}

const MonacoEditor = forwardRef<any, MonacoEditorProps>(({ initialValue, language, onChange, onSave, height = '400px' }, ref) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useImperativeHandle(ref, () => ({
    focus: () => {
      monacoEditorRef.current?.focus();
    },
    getValue: () => {
      return monacoEditorRef.current?.getValue();
    },
  }));

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      editor.onDidChangeModelContent(() => {
        if (onChange) {
          onChange(editor.getValue());
        }
      });

      // Delay initialization to ensure the editor is fully loaded
      setTimeout(() => {
        try {
          const vimMode = new VimMode(editor);
          vimModeRef.current = vimMode;

          // Define Vim commands
          vimMode.defineEx('w', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
          });

          vimMode.defineEx('q', '', () => {
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });

          vimMode.defineEx('wq', '', () => {
            if (onSave) {
              onSave(editor.getValue());
            }
            if (editorRef.current) {
              editorRef.current.style.display = 'none'; // Hide the editor
            }
          });

        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }
      }, 100); // Delay for 100ms

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language, onChange, onSave]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
});

export default MonacoEditor;

Additional Tips

  1. Ensure Dependencies: Make sure you have the vim-monaco package properly installed and imported.

  2. CSS for Status Bar: Include CSS for the Vim status bar to ensure it displays correctly.

  3. Console Logs: Keep the console.log statements to debug and understand where the issue might be occurring.

If the problem persists, you might want to check the specific version of vim-monaco you are using and ensure it is compatible with the version of monaco-editor you have.

The error you're encountering suggests that there's an issue with accessing SelectionDirection in the adapter.ts file, which seems to be part of the vim-monaco library or its integration. This likely means that the Monaco editor or some part of its API is not fully initialized or available when the Vim mode is being set up.

Steps to Address the Issue:

  1. Check for SelectionDirection: Ensure that SelectionDirection is properly defined and accessible. You might need to add null checks or ensure that the Monaco editor instance is fully ready.

  2. Delay Initialization: While increasing the timeout can help, it's not a guaranteed solution. Instead, you should ensure that the editor and its selection API are fully initialized.

  3. Debug adapter.ts: Add logging or additional checks in adapter.ts to understand why SelectionDirection is undefined.

Temporary Workaround:

You can add null checks in your adapter.ts file to avoid the TypeError. Here’s an example based on the context you provided:

// src/adapter.ts
const selection = editor.getSelection();
if (selection && selection.SelectionDirection) {
  const selectionDirection = selection.SelectionDirection;
  // Proceed with your logic...
} else {
  console.error('Selection or SelectionDirection is undefined');
}

Updated MonacoEditor.tsx with Additional Checks:

Here’s an updated version of your MonacoEditor.tsx that includes additional null checks and logging:

You’re right; modifying library code is not ideal, especially when it works in other environments like JS Fiddle. Given the library works in JS Fiddle, the issue is likely related to how the library is being integrated or the environment in which it’s running in your React app.

Let's focus on ensuring that the Monaco editor and vim-monaco library are correctly initialized in your React app.

Steps to Ensure Proper Initialization:

  1. Ensure Monaco Environment Configuration: The JS Fiddle example configures the Monaco environment. Ensure you've correctly configured this in your React app.

  2. Ensure Proper Loading Sequence: The order and timing of loading Monaco and vim-monaco might be causing issues. Ensure these libraries are loaded and initialized in the correct sequence.

  3. Check for Compatibility Issues: Ensure the versions of monaco-editor and vim-monaco you are using are compatible.

Here is a more refined approach to ensure proper initialization and configuration:

Monaco Environment Configuration

Ensure you configure the Monaco environment correctly before initializing the editor. You can do this in a separate file or directly in your component.

Updated MonacoEditor.tsx with Proper Configuration:

// src/components/MonacoEditor.tsx
import { useEffect, useRef, forwardRef, useImperativeHandle } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Import the CSS file

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  onChange?: (value: string) => void;
  onSave?: (value: string) => void;
  height?: string;

Sure, let's simplify your `MonacoEditor.tsx` to the most minimal implementation that integrates Monaco Editor and `vim-monaco`. This will help us identify if there's a fundamental issue with the setup.

### Minimal Implementation of `MonacoEditor.tsx`

We'll strip down the component to its basics, ensuring it just renders the Monaco Editor with Vim mode enabled. We'll also use a minimal configuration for Monaco and Vim mode.

```tsx
// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      const initializeVimMode = () => {
        try {
          const vimMode = new VimMode(editor);
          vimModeRef.current = vimMode;
        } catch (error) {
          console.error('Error initializing VimMode:', error);
        }
      };

      // Delay initialization to ensure the editor is fully loaded
      setTimeout(initializeVimMode, 2000);

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Additional Steps

  1. Ensure CSS File: Ensure you have a MonacoEditor.css file with basic styles, especially for .monaco-editor-container and .vim-status-bar.
/* src/components/MonacoEditor.css */
.monaco-editor-container {
  position: relative;
  width: 100%;
}

.vim-status-bar {
  position: absolute;
  bottom: 0;
  width: 100%;
  background-color: #2c2c2c;
  color: white;
  text-align: left;
  padding: 5px;
}
  1. Ensure Proper Dependencies: Make sure monaco-editor and vim-monaco are installed and imported correctly in your project.

  2. Check Browser Console: After running the application, check the browser console for any additional errors or warnings that might give more context.

Running the Minimal Implementation

  1. Ensure Environment Configuration: If you see issues related to worker scripts, ensure you have the correct configuration for Monaco Editor’s worker scripts.
// Ensure this configuration is somewhere in your project setup
if (typeof window !== 'undefined') {
  (window as any).MonacoEnvironment = {
    getWorkerUrl: function (moduleId: string, label: string) {
      if (label === 'json') {
        return '/json.worker.js';
      }
      if (label === 'css') {
        return '/css.worker.js';
      }
      if (label === 'html') {
        return '/html.worker.js';
      }
      if (label === 'typescript' || label === 'javascript') {
        return '/ts.worker.js';
      }
      return '/editor.worker.js';
    },
  };
}
  1. Run Your React Application: Start your React application and navigate to the component that renders MonacoEditor.tsx.

If the minimal implementation works without errors, you can gradually add back features (like onChange, onSave, and custom Vim commands) to identify the specific part causing issues. If it still throws the same error, it might indicate a deeper compatibility issue, which might require looking into specific versions of monaco-editor and vim-monaco or their integration with React.

It's clear that the issue is directly related to initializing the VimMode with the Monaco editor. Given that the Monaco editor works fine without the VimMode initialization, and the error occurs even if the initialization code isn't called, there might be an issue with how the vim-monaco module is being imported or used.

Potential Solutions

  1. Check vim-monaco Version: Ensure that the version of vim-monaco you are using is compatible with your version of monaco-editor.

  2. Import Method: Ensure that VimMode is being imported correctly from vim-monaco.

  3. Monaco Configuration: Ensure that the Monaco environment is correctly configured to load the required worker scripts.

Minimal Implementation with Additional Checks

To further isolate the issue, let’s use a minimal implementation with additional checks and logging:

  1. Ensure Proper Imports: Ensure that monaco-editor and vim-monaco are correctly imported.

  2. Add Logging: Add additional logging to see if there are any import issues or undefined values.

Updated MonacoEditor.tsx Component

Here’s the updated minimal implementation with logging and proper checks:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Adding try-catch and logging to capture the issue
      try {
        const vimMode = new VimMode(editor);
        vimModeRef.current = vimMode;
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Additional Steps

  1. Check Browser Console: After running the application, check the console for the logs to see if the VimMode is being created or if it throws an error.

  2. Check Dependencies: Ensure that you have the correct versions of monaco-editor and vim-monaco installed. Compatibility issues can often cause such errors.

# Check installed versions
npm list monaco-editor vim-monaco
  1. Ensure Correct Setup: Make sure your project is correctly set up to load the necessary worker scripts for Monaco Editor. This can sometimes cause issues if not set up correctly.

Example Version Check

Ensure you have compatible versions of the packages:

// package.json
{
  "dependencies": {
    "monaco-editor": "^0.30.1", // Example version, ensure it's compatible
    "vim-monaco": "^1.0.3" // Example version, ensure it's compatible
  }
}

Final Note

If the issue persists, consider testing with different versions of monaco-editor and vim-monaco to identify if there is a specific version causing the issue. Compatibility issues between different versions can often lead to such errors.

The error you're seeing indicates that TypeScript cannot find the type declarations for the vim-monaco module. Even though the module has type declarations, the way the package is structured with respect to package.json can sometimes cause issues.

Steps to Resolve the TypeScript Declaration Issue

  1. Create a Module Declaration: If the library's type declarations are not being resolved correctly, you can manually create a module declaration in your project to help TypeScript understand the types.

  2. Check package.json: Ensure that the package.json of vim-monaco correctly points to its type declarations. You can inspect the node_modules/vim-monaco/package.json file to verify this.

Creating a Custom Module Declaration

You can create a custom type declaration file in your project to manually declare the module and its types.

  1. Create a types Directory: Create a types directory in your project if it doesn't already exist.

  2. Add a Declaration File: Create a new file named vim-monaco.d.ts in the types directory with the following content:

// types/vim-monaco.d.ts
declare module 'vim-monaco' {
  import * as monaco from 'monaco-editor';

  export class VimMode {
    constructor(editor: monaco.editor.IStandaloneCodeEditor);
    dispose(): void;
  }

  export function makeDomStatusBar(parent: HTMLElement, focusEditor: () => void): HTMLElement;
}
  1. Include the Types Directory in tsconfig.json: Ensure that TypeScript includes the custom types directory. Add or update the typeRoots in your tsconfig.json:
// tsconfig.json
{
  "compilerOptions": {
    // other options...
    "typeRoots": ["./node_modules/@types", "./types"]
  }
}

Updated MonacoEditor.tsx Component

With the custom type declarations, your MonacoEditor.tsx should now look like this:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Adding try-catch and logging to capture the issue
      try {
        const vimMode = new VimMode(editor);
        vimModeRef.current = vimMode;
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Final Steps

  1. Restart TypeScript Server: If you're using an editor like VSCode, restart the TypeScript server to ensure it picks up the new type declarations.
  2. Run Your Application: Re-run your application to check if the issue is resolved.

By manually creating a module declaration, you should be able to resolve the TypeScript errors and ensure that the vim-monaco library integrates correctly with your Monaco Editor setup.

You're correct that ideally, you should be able to use the type declarations provided by the vim-monaco package without creating your own. The error you're encountering indicates there might be deeper integration issues between monaco-editor and vim-monaco.

Steps to Troubleshoot

  1. Verify vim-monaco Package Structure: Ensure that the vim-monaco package has its type declarations correctly specified in its package.json.

  2. Compatibility Check: Verify the versions of monaco-editor and vim-monaco you are using to make sure they are compatible.

  3. Project Setup: Ensure that the project setup and configuration (like Vite) is correctly handling the monaco-editor and vim-monaco dependencies.

Verifying vim-monaco Type Declarations

Check node_modules/vim-monaco/package.json to see if it correctly points to its type declarations:

{
  "name": "vim-monaco",
  "version": "1.0.3",
  "main": "dist/vim-monaco.umd.js",
  "types": "dist/index.d.ts",
  "exports": {
    ".": {
      "import": "./dist/vim-monaco.modern.js",
      "require": "./dist/vim-monaco.umd.js",
      "types": "./dist/index.d.ts"
    }
  }
}

Ensuring Correct Versions

Ensure you have compatible versions of monaco-editor and vim-monaco:

Simplified Example

Let’s attempt a more simplified example to ensure basic integration:

  1. Simplified MonacoEditor.tsx:

    // src/components/MonacoEditor.tsx
    import { useEffect, useRef } from 'react';
    import * as monaco from 'monaco-editor';
    import { VimMode } from 'vim-monaco';
    import './MonacoEditor.css'; // Ensure this file exists and has the required styles
    
    interface MonacoEditorProps {
      initialValue: string;
      language: 'javascript' | 'typescript' | 'markdown';
      height?: string;
    }
    
    const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
      const editorRef = useRef<HTMLDivElement>(null);
      const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
      const vimModeRef = useRef<VimMode | null>(null);
    
      useEffect(() => {
        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });
    
          monacoEditorRef.current = editor;
    
          console.log('Monaco Editor created:', editor);
    
          try {
            const vimMode = new VimMode(editor);
            vimModeRef.current = vimMode;
            console.log('VimMode created:', vimMode);
          } catch (error) {
            console.error('Error initializing VimMode:', error);
          }
    
          return () => {
            if (vimModeRef.current) {
              vimModeRef.current.dispose();
            }
            editor.dispose();
          };
        }
      }, [initialValue, language]);
    
      return (
        <div>
          <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
          <div id="status" className="vim-status-bar"></div>
        </div>
      );
    };
    
    export default MonacoEditor;
  2. Ensure Proper CSS:

    /* src/components/MonacoEditor.css */
    .monaco-editor-container {
      position: relative;
      width: 100%;
    }
    
    .vim-status-bar {
      position: absolute;
      bottom: 0;
      width: 100%;
      background-color: #2c2c2c;
      color: white;
      text-align: left;
      padding: 5px;
    }
  3. Verify Vite Configuration:

    Ensure your Vite configuration is correctly set up to handle monaco-editor:

    // vite.config.ts
    import { defineConfig } from 'vite';
    import react from '@vitejs/plugin-react';
    import path from 'path';
    import monacoEditorPlugin from 'vite-plugin-monaco-editor';
    
    export default defineConfig({
      plugins: [
        react(),
        monacoEditorPlugin()
      ],
      resolve: {
        alias: {
          '/@': path.resolve(__dirname, './src'),
        },
      },
    });

The fact that vim-monaco specifies monaco-editor version ^0.50.0 means you should use a compatible version of monaco-editor in your project. The package managers (npm vs. yarn) typically don't cause issues unless there are specific conflicts or version mismatches.

Steps to Resolve the Issue

  1. Ensure Compatible Versions: Make sure your project is using the same versions of monaco-editor and vim-monaco as specified in vim-monaco's package.json.

  2. Install Dependencies with Yarn: Use Yarn to install the necessary dependencies in your project.

  3. Building vim-monaco: If you need to build vim-monaco from source, you can use either npm or yarn. However, for consistency, you might prefer using Yarn.

Ensure Compatible Versions

Update your package.json to use the compatible versions:

// package.json
{
  "dependencies": {
    "monaco-editor": "^0.50.0",
    "vim-monaco": "^1.0.3"
  }
}

Then run:

yarn install

Building vim-monaco from Source

If you want to build vim-monaco from source, clone the repository and build it using Yarn:

# Clone the vim-monaco repository
git clone https://github.com/pollrobots/vim-monaco.git
cd vim-monaco

# Install dependencies using Yarn
yarn install

# Build the project using Yarn
yarn build

Minimal Implementation of MonacoEditor.tsx

Here’s the minimal implementation again, ensuring you’re using the correct versions:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
  const vimModeRef = useRef<VimMode | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      monacoEditorRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Adding try-catch and logging to capture the issue
      try {
        const vimMode = new VimMode(editor);
        vimModeRef.current = vimMode;
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (vimModeRef.current) {
          vimModeRef.current.dispose();
        }
        editor.dispose();
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Ensure Proper CSS

Ensure you have the CSS file with the necessary styles:

/* src/components/MonacoEditor.css */
.monaco-editor-container {
  position: relative;
  width: 100%;
}

.vim-status-bar {
  position: absolute;
  bottom: 0;
  width: 100%;
  background-color: #2c2c2c;
  color: white;
  text-align: left;
  padding: 5px;
}

Run Your Application

Run your application and check if the issue persists. If the error still occurs, it might indicate a deeper issue with the integration of vim-monaco and monaco-editor in your specific setup.

Additional Debugging

  1. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.
  2. Verify Imports: Ensure that monaco-editor and vim-monaco are correctly imported and used in your code.

By ensuring you're using compatible versions and correctly building and integrating the dependencies, you should be able to resolve the issues you're encountering.

    "microbundle": "^0.15.1",
    "monaco-editor": "^0.50.0",
    "typescript": "^5.5.3"
  },
  "peerDependencies": {
    "monaco-editor": "^0.50.0"
  }
}

Build Steps using Yarn

  1. Clone the Repository and Navigate to the Directory:

    git clone https://github.com/pollrobots/vim-monaco.git
    cd vim-monaco
  2. Install Dependencies with Yarn:

    yarn install
  3. Build the Project with Yarn:

    yarn build

Ensure Integration in Your Project

After building vim-monaco from source, ensure that your project correctly integrates the newly built version.

  1. Link the Built Package: Use Yarn to link the built vim-monaco package to your project.

    # In vim-monaco directory
    yarn link
    
    # In your project directory
    yarn link vim-monaco
  2. Verify the Integration: Ensure your MonacoEditor.tsx and package.json are correctly set up to use the linked vim-monaco.

Debugging the Integration

  1. Check for TypeScript Issues: Ensure that TypeScript correctly picks up the type declarations from vim-monaco. If necessary, use a custom type declaration as a temporary workaround, as previously suggested.

  2. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.

Final Verification

  1. Run Your Application: After linking and ensuring the correct setup, run your application to verify if the issue persists.

  2. Check for Compatibility: If the issue still occurs, verify the compatibility of monaco-editor and vim-monaco and ensure there are no underlying conflicts.

By adapting the build script for Yarn and ensuring a smooth integration, you should be able to resolve the issues you're encountering with vim-monaco and monaco-editor.

Certainly! The yarn link command is used to link a local package to your project. This is especially useful during development when you want to test changes in a package without having to publish it to a registry like npm or Yarn.

How yarn link Works

  1. Creating a Link: When you run yarn link in the vim-monaco directory, it creates a global symlink to that directory. This means that the vim-monaco package is now available globally on your system.

  2. Linking to Your Project: When you run yarn link vim-monaco in your project directory, Yarn creates a symlink in your project's node_modules directory that points to the globally linked vim-monaco package.

This allows your project to use the local version of vim-monaco instead of fetching it from a remote registry. Any changes you make to the vim-monaco package will be immediately reflected in your project.

Steps to Link vim-monaco

1. Link the vim-monaco Package Globally

Navigate to the vim-monaco directory and run the following command:

# Navigate to the vim-monaco directory
cd path/to/vim-monaco

# Create a global symlink for vim-monaco
yarn link

This command creates a global link to the vim-monaco package.

2. Link the Globally Linked vim-monaco to Your Project

Navigate to your project directory and run the following command:

# Navigate to your project directory
cd path/to/your/project

# Link the globally linked vim-monaco to your project
yarn link vim-monaco

This command creates a symlink in your project's node_modules directory that points to the globally linked vim-monaco.

Verification and Usage

After linking, you can verify that your project is using the local version of vim-monaco:

  1. Check node_modules: In your project's node_modules directory, you should see a symlink for vim-monaco that points to the local vim-monaco directory.

  2. Run Your Project: Start your development server and test the integration to ensure that the changes in vim-monaco are being reflected in your project.

Example Workflow

  1. Develop and Build vim-monaco:

    • Make changes to the vim-monaco source code.
    • Build the project using yarn build.
  2. Link vim-monaco Globally:

    cd path/to/vim-monaco
    yarn link
  3. Link vim-monaco to Your Project:

    cd path/to/your/project
    yarn link vim-monaco
  4. Run Your Project:

    • Start your development server.
    • Verify that the changes in vim-monaco are reflected in your project.

Example Directory Structure

  • /path/to/vim-monaco

    • Contains the source code for the vim-monaco package.
  • /path/to/your/project

    • Contains your React project that uses vim-monaco.

By linking the vim-monaco package, you can develop and test changes in vim-monaco without having to publish it to a registry. This can greatly speed up your development workflow and make it easier to debug issues.

Let's walk through the steps to verify and debug the integration of the locally linked vim-monaco package.

Verify the Integration

  1. Check node_modules: Ensure that the vim-monaco package in your project's node_modules directory is a symlink pointing to your local vim-monaco directory.

    cd path/to/your/project/node_modules
    ls -l vim-monaco

    The output should show that vim-monaco is a symlink to your local vim-monaco directory.

  2. Check package.json: Ensure your project's package.json correctly lists vim-monaco as a dependency (it should be listed, and yarn link will override it to point to the local version).

    {
      "dependencies": {
        "monaco-editor": "^0.50.0",
        "vim-monaco": "^1.0.3"
      }
    }

Debugging the Integration

  1. Check for TypeScript Issues: Ensure that TypeScript correctly picks up the type declarations from vim-monaco.

    • Ensure typescript is installed in your project.
    • Ensure tsconfig.json includes the types directory (if you created a custom type declaration).
    // tsconfig.json
    {
      "compilerOptions": {
        // other options...
        "typeRoots": ["./node_modules/@types", "./types"]
      }
    }
  2. Check Browser Console: Look for any additional errors or warnings in the browser console.

    • Open the Developer Tools in your browser (usually by pressing F12).
    • Go to the Console tab to see any errors or warnings.

Step into Local vim-monaco Code

With the local vim-monaco linked, you can step into that code using the following steps:

  1. Set Breakpoints: In your IDE (e.g., VSCode), open the vim-monaco package source files and set breakpoints where you suspect the issue might be.

  2. Start Debugging: Start your React application in debug mode. In VSCode, you can create a launch configuration for debugging.

    // .vscode/launch.json
    {
      "version": "0.2.0",
      "configurations": [
        {
          "type": "chrome",
          "request": "launch",
          "name": "Launch Chrome against localhost",
          "url": "http://localhost:3000", // Adjust to your local development URL
          "webRoot": "${workspaceFolder}"
        }
      ]
    }

    Run the debugger, and it should hit the breakpoints you set in the vim-monaco source files.

  3. Verify the Linked Package: You can verify that your project is using the linked vim-monaco by adding a console log or modifying the code slightly in the vim-monaco source files. These changes should be immediately reflected in your running application.

Example Troubleshooting Steps

  1. Open vim-monaco Source Code: Open the adapter.ts file (or the file where the error occurs) in the vim-monaco package.

  2. Set Breakpoints: Set breakpoints on the lines where the error occurs.

  3. Add Console Logs: Add console logs to see the state of the variables causing the error.

    // Example in adapter.ts
    console.log('SelectionDirection:', someVariable.SelectionDirection);
  4. Run the Application: Start your application and trigger the code that causes the error. The breakpoints should be hit, and the console logs should help you understand the issue better.

Summary

By following these steps, you can verify that your project is using the locally linked vim-monaco package and debug the integration to resolve the issues you're encountering. This process allows you to step into the vim-monaco code, set breakpoints, and add console logs to understand and fix the problem.

The typical workflow for using yarn link does not require you to yarn add the package first. Instead, you'll link the local package directly into your project. Here’s the step-by-step process to ensure the linked package is correctly integrated:

Step-by-Step Process

  1. Remove Existing vim-monaco: You've already done this step by running:

    yarn remove vim-monaco
  2. Link vim-monaco Globally: Navigate to the vim-monaco directory and create a global link.

    cd path/to/vim-monaco
    yarn link
  3. Link vim-monaco to Your Project: Navigate to your project directory and link the globally linked vim-monaco.

    cd path/to/your/project
    yarn link vim-monaco

Your tsconfig.json

Your tsconfig.json already looks well-configured. There's no need to change it for the linking process.

Verify the Integration

  1. Check node_modules: Ensure that vim-monaco is a symlink in your project's node_modules directory.

    cd path/to/your/project/node_modules
    ls -l vim-monaco

    The output should show vim-monaco as a symlink to the local vim-monaco directory.

  2. Check Package.json: Your package.json should not list vim-monaco under dependencies if you are using the linked version. The link will override the dependency.

Debugging the Integration

  1. Open vim-monaco Source Code: Open the vim-monaco package source files in your IDE.

  2. Set Breakpoints: Set breakpoints in the source files where the error occurs (e.g., adapter.ts).

  3. Run the Application: Start your application in debug mode. This allows you to step into the code and see the values of variables.

Example Launch Configuration for VSCode

If you are using VSCode, you can create a launch configuration for debugging.

// .vscode/launch.json
{
  "version": "0.2.0",
  "configurations": [
    {
      "type": "chrome",
      "request": "launch",
      "name": "Launch Chrome against localhost",
      "url": "http://localhost:3000", // Adjust to your local development URL
      "webRoot": "${workspaceFolder}"
    }
  ]
}

Final Steps

  1. Start Debugging: Run the debugger, and it should hit the breakpoints you set in the vim-monaco source files.

  2. Check Console Logs: Add console logs to the vim-monaco source code to see the state of variables causing the error.

    // Example in adapter.ts
    console.log('SelectionDirection:', someVariable.SelectionDirection);
  3. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.

Verification and Troubleshooting

  • Verify Symlink: Ensure that vim-monaco is correctly symlinked in the node_modules directory.

  • Run Application: Start your application and verify if the changes in vim-monaco are reflected.

By following these steps, you can ensure that your project uses the locally linked vim-monaco package and debug the integration effectively. This process allows you to step into the vim-monaco code, set breakpoints, and add console logs to understand and fix the problem.

Thank you for clarifying the steps and the issue you are encountering.

Correct Steps to Link and Verify vim-monaco

  1. Remove Existing vim-monaco: You correctly removed the existing vim-monaco from package.json:

    yarn remove vim-monaco
  2. Link vim-monaco Globally: Navigate to the vim-monaco directory and create a global link:

    cd path/to/vim-monaco
    yarn link
  3. Link vim-monaco to Your Project: Navigate to your project directory and link the globally linked vim-monaco:

    cd path/to/your/project
    yarn link vim-monaco

Verifying the Link

After running yarn link vim-monaco, you should see vim-monaco in your project's node_modules directory as a symlink. If the symlink is not created, you might need to troubleshoot the linking process.

Add vim-monaco Back to package.json for Tracking

Even though yarn link does not add the package back to package.json, you can manually add it for tracking purposes without actually installing it from the registry.

  1. Manually Add vim-monaco to package.json: Open your package.json and manually add vim-monaco to the dependencies:

    {
      "dependencies": {
        "monaco-editor": "^0.50.0",
        "vim-monaco": "link:../path/to/vim-monaco"
      }
    }
  2. Verify the Symlink: Ensure that the symlink is correctly created in the node_modules directory:

    cd path/to/your/project/node_modules
    ls -l vim-monaco

Troubleshooting the Linking Process

If the symlink is not created, you can try the following steps:

  1. Ensure yarn link was Successful: Verify that yarn link in the vim-monaco directory reported success.

  2. Manually Create the Symlink: If yarn link does not create the symlink, you can manually create it:

    cd path/to/your/project/node_modules
    ln -s ../../path/to/vim-monaco vim-monaco

Final Steps

  1. Run Your Application: Start your application and verify if the changes in vim-monaco are reflected.

  2. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.

  3. Debugging: Step into the vim-monaco code, set breakpoints, and add console logs to understand and fix the problem.

Summary

By manually adding vim-monaco to package.json and ensuring the symlink is correctly created, you can verify that your project uses the locally linked vim-monaco package. This process allows you to step into the vim-monaco code, set breakpoints, and add console logs to understand and fix the problem.

Thank you for the detailed steps and the information. It seems like you've correctly linked the vim-monaco package, but there might be additional steps required to ensure proper debugging and symbol loading.

Ensure Proper Linking and Debugging

  1. Verify the Symlink: Ensure that the symlink is correctly created in the node_modules directory:

    cd path/to/your/project/node_modules
    ls -l vim-monaco

    The output should show vim-monaco as a symlink to your local vim-monaco directory.

  2. Manually Add to package.json: Ensure that your package.json correctly tracks vim-monaco as a linked dependency:

    {
      "dependencies": {
        "monaco-editor": "^0.50.0",
        "vim-monaco": "link:../path/to/vim-monaco"
      }
    }

Ensure Proper Build and Debug Symbols

If you need debug symbols or source maps, you should ensure that vim-monaco is built with these options enabled.

  1. Modify vim-monaco Build Script: Ensure that the vim-monaco build script generates source maps. You can modify the microbundle command in the package.json to include source maps:

    // vim-monaco/package.json
    {
      "scripts": {
        "clean": "rm -rf dist",
        "build": "yarn run clean && yarn run digraphs && microbundle --sourcemap",
        "digraphs": "node src/digraph.src.js",
        "prepublishOnly": "yarn run build"
      }
    }
  2. Rebuild vim-monaco: Rebuild vim-monaco to generate the source maps:

    cd path/to/vim-monaco
    yarn build
  3. Ensure Source Maps are Loaded: When running your application, ensure that the source maps are loaded in the browser's Developer Tools. This should allow breakpoints to bind correctly.

Debugging in VSCode

  1. Configure VSCode for Debugging: Ensure that your VSCode is correctly configured for debugging. Create a .vscode/launch.json file if it doesn't exist:

    // .vscode/launch.json
    {
      "version": "0.2.0",
      "configurations": [
        {
          "type": "chrome",
          "request": "launch",
          "name": "Launch Chrome against localhost",
          "url": "http://localhost:3000", // Adjust to your local development URL
          "webRoot": "${workspaceFolder}"
        }
      ]
    }
  2. Set Breakpoints in vim-monaco: Open the vim-monaco package source files in VSCode and set breakpoints where you suspect the issue might be.

  3. Start Debugging: Start the debugger in VSCode and verify that the breakpoints are hit.

Additional Steps

  1. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.

  2. Clear Cache: Sometimes, browser caching issues can prevent the latest source maps and code from being loaded. Clear your browser cache or use an incognito window to test.

Summary

By ensuring that the vim-monaco package is built with source maps and correctly linked, you should be able to step into the code and debug effectively. Proper configuration in VSCode and clearing the browser cache can also help in ensuring that breakpoints bind correctly and you can see the debug symbols.

It seems the issue is that window.monaco is not being set as expected. This could be due to the order of script execution or the way monaco-editor is being initialized in your project.

Here are the steps to ensure that monaco-editor is correctly loaded and available on the window object:

Ensure Monaco is Loaded Correctly

  1. Check Initialization Script: Ensure that monaco-editor is being correctly initialized and assigned to the window object. This typically happens in a script that runs before any dependent code.

    For example, in your MonacoEditor.html file:

    <!-- src/components/MonacoEditor.html -->
    <div id="status" style="display: block;">
      <span>--NORMAL--</span><span></span><span class="vim-notification"></span><span style="float: right"></span>
    </div>
    <script src="https://unpkg.com/[email protected]/min/vs/loader.js"></script>
    <script>
      const baseUrl = "https://unpkg.com/[email protected]/min/";
      require.config({
        paths: {
          vs: `${baseUrl}/vs`,
          "vim-monaco": "https://unpkg.com/[email protected]/dist"
        }
      });
      require(['vs/editor/editor.main'], (monaco) => {
        window.monaco = monaco;
        require(['vim-monaco/vim-monaco.umd', 'index'], (vim, index) => {
          window.vim = vim;
          index.main();
        }, (err) => {
          console.error('Error loading vim-monaco', err);
        });
      }, (err) => {
        console.error('Error loading monaco:', err);
      });
    </script>
  2. Ensure Monaco is Available Before Usage: In your adapter.ts file, you need to ensure that window.monaco is available before you access it. You can add a check to see if window.monaco is defined.

    /**
     * An adapter to make CodeMirror's vim bindings work with monaco
     */
    import { IPosition, IRange, ISelection } from "monaco-editor";
    import monaco from "monaco-editor";
    import { StatusBarInputOptions, ModeChangeEvent } from "./statusbar";
    import { ExCommandOptionalParameters } from "./keymap_vim";
    import { Pos, getEventKeyName, makePos } from "./common";
    
    console.log('CodeMirror adapter loaded', window);
    
    if (window.monaco && window.monaco.SelectionDirection) {
      const SelectionDirection = window.monaco.SelectionDirection;
    } else {
      console.error('Monaco is not loaded yet');
    }
    
    export class CmSelection {
      /// Where the selection started from
      readonly anchor: Pos;
      /// Where the cursor currently is
      readonly head: Pos;
    
      constructor(anchor: Pos, head: Pos) {
        this.anchor = anchor;
        this.head = head;
      }
    }

Loading Monaco in a React Component

If you're using Monaco in a React component, ensure that Monaco is loaded before the component tries to use it.

  1. Load Monaco in a React Component: Ensure that monaco-editor is correctly loaded before using it in your React component.

    // src/components/MonacoEditor.tsx
    import React, { useEffect, useRef } from 'react';
    import * as monaco from 'monaco-editor';
    import { VimMode } from 'vim-monaco';
    
    interface MonacoEditorProps {
      initialValue: string;
      language: 'javascript' | 'typescript' | 'markdown';
      height?: string;
    }
    
    const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
      const editorRef = useRef<HTMLDivElement>(null);
      const monacoEditorRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    
      useEffect(() => {
        if (!editorRef.current) return;
    
        const loadMonaco = async () => {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });
    
          monacoEditorRef.current = editor;
    
          // Ensure that VimMode is loaded after editor creation
          const VimMode = (await import('vim-monaco')).VimMode;
          new VimMode(editor);
        };
    
        loadMonaco();
    
        return () => {
          monacoEditorRef.current?.dispose();
        };
      }, [initialValue, language]);
    
      return <div

Thank you for the clarification. Let's focus on ensuring that monaco is correctly initialized and available before vim-monaco is used. We can also simplify the use of useRef to make sure everything is correctly assigned.

Ensure Monaco is Available Before Usage

To ensure that monaco is correctly initialized and assigned to the window object before using vim-monaco, you can follow these steps:

  1. Check Initialization: Ensure that monaco is properly initialized within the useEffect hook before vim-monaco is used.

  2. Simplify useRef Usage: Use a single ref for the editor and handle vimMode within the same useEffect to avoid unnecessary complexity.

Updated MonacoEditor.tsx

Here's an updated version of your MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const vimMode = new VimMode(editor);
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Ensure Monaco is Loaded Correctly

To avoid potential issues with window.monaco, you can ensure that it's available globally (though this is less common in React applications):

  1. Set window.monaco: If you need window.monaco, ensure it is set explicitly during initialization.

Example of Ensuring Monaco Availability

If you need to ensure window.monaco is available, you could add:

useEffect(() => {
  if (editorRef.current) {
    const editor = monaco.editor.create(editorRef.current, {
      value: initialValue,
      language: language,
      theme: 'vs-dark',
      automaticLayout: true,
    });

    // Ensure monaco is available globally
    window.monaco = monaco;

    editorInstanceRef.current = editor;

    console.log('Monaco Editor created:', editor);

    // Ensure VimMode is loaded after editor creation
    try {
      const vimMode = new VimMode(editor);
      console.log('VimMode created:', vimMode);
    } catch (error) {
      console.error('Error initializing VimMode:', error);
    }

    return () => {
      if (editorInstanceRef.current) {
        editorInstanceRef.current.dispose();
      }
    };
  }
}, [initialValue, language]);

Debugging Tips

  1. Check Browser Console: Look for any additional errors or warnings in the browser console that might give more context.

  2. Add Console Logs: Add console logs to see the state of variables causing the error.

    // Example in adapter.ts
    console.log('SelectionDirection:', window.monaco?.SelectionDirection);
  3. Step Through Code: Use the browser's Developer Tools to step through the code and ensure monaco is loaded before it's used.

Summary

By ensuring that monaco is correctly initialized and simplifying the useRef usage, you can avoid issues related to the availability of monaco and integration with vim-monaco. Proper debugging and ensuring window.monaco is set correctly will help in resolving the issues you're encountering.

To resolve the TypeScript error related to adding a property to the window object, you need to extend the Window interface with the monaco property. This can be done in a TypeScript declaration file.

Step-by-Step Solution

  1. Create a TypeScript Declaration File: Create a file named global.d.ts in the src directory (or another appropriate location) to extend the Window interface.

  2. Extend the Window Interface: Add the following code to global.d.ts to extend the Window interface:

    // src/global.d.ts
    import * as monaco from 'monaco-editor';
    
    declare global {
      interface Window {
        monaco: typeof monaco;
      }
    }
  3. Update Your MonacoEditor.tsx: With the Window interface extended, you can safely assign monaco to window.monaco in your MonacoEditor.tsx file.

Complete MonacoEditor.tsx with Extended Window Interface

Here's the updated MonacoEditor.tsx file:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      // Ensure monaco is available globally
      window.monaco = monaco;

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const vimMode = new VimMode(editor);
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Summary

  • Extend the Window Interface: Create a global.d.ts file to extend the Window interface with the monaco property.
  • Assign monaco to window.monaco: With the interface extended, you can safely assign monaco to window.monaco in your MonacoEditor.tsx file.

This approach ensures that TypeScript recognizes the monaco property on the window object, resolving the error and allowing the rest of your code to run as expected.

Thank you for the detailed explanation. It seems the issue might be related to the timing of when window.monaco is being accessed in adapter.ts. Specifically, adapter.ts might be executed before window.monaco is set.

Ensuring window.monaco is Available

To ensure that window.monaco is available before adapter.ts accesses it, you can use a promise or an event-based approach to guarantee the availability of monaco.

Solution 1: Using a Promise

You can create a promise to ensure monaco is available before your code in adapter.ts runs.

  1. Create a Promise for Monaco Initialization:

    // src/components/MonacoEditor.tsx
    import { useEffect, useRef } from 'react';
    import * as monaco from 'monaco-editor';
    import { VimMode } from 'vim-monaco';
    import './MonacoEditor.css'; // Ensure this file exists and has the required styles
    
    interface MonacoEditorProps {
      initialValue: string;
      language: 'javascript' | 'typescript' | 'markdown';
      height?: string;
    }
    
    // Create a promise to ensure monaco is available
    const monacoReady = new Promise<void>((resolve) => {
      window.monacoReadyResolve = resolve;
    });
    
    declare global {
      interface Window {
        monaco: typeof monaco;
        monacoReadyResolve: () => void;
      }
    }
    
    const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
      const editorRef = useRef<HTMLDivElement>(null);
      const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);
    
      useEffect(() => {
        if (editorRef.current) {
          const editor = monaco.editor.create(editorRef.current, {
            value: initialValue,
            language: language,
            theme: 'vs-dark',
            automaticLayout: true,
          });
    
          // Ensure monaco is available globally
          window.monaco = monaco;
          window.monacoReadyResolve();
    
          editorInstanceRef.current = editor;
    
          console.log('Monaco Editor created:', editor);
    
          // Ensure VimMode is loaded after editor creation
          try {
            const vimMode = new VimMode(editor);
            console.log('VimMode created:', vimMode);
          } catch (error) {
            console.error('Error initializing VimMode:', error);
          }
    
          return () => {
            if (editorInstanceRef.current) {
              editorInstanceRef.current.dispose();
            }
          };
        }
      }, [initialValue, language]);
    
      return (
        <div>
          <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
          <div id="status" className="vim-status-bar"></div>
        </div>
      );
    };
    
    export default MonacoEditor;
  2. Modify adapter.ts to Use the Promise:

    // src/adapter.ts
    import { IPosition, IRange, ISelection } from 'monaco-editor';
    import { StatusBarInputOptions, ModeChangeEvent } from './statusbar';
    import { ExCommandOptionalParameters } from './keymap_vim';
    import { Pos, getEventKeyName, makePos } from './common';
    
    console.log('CodeMirror adapter loaded', window);
    
    window.monacoReady.then(() => {
      const SelectionDirection = window.monaco.SelectionDirection;
    
      export class CmSelection {
        /// Where the selection started from
        readonly anchor: Pos;
        /// Where the cursor currently is
        readonly head: Pos;
    
        constructor(anchor: Pos, head: Pos) {
          this.anchor = anchor;
          this.head = head;
        }
      }
    }).catch(error => {
      console.error('Error waiting for monaco:', error);
    });

Solution 2: Using Event-Based Approach

Alternatively, you can use a custom event to ensure monaco is available before your code in adapter.ts runs.

  1. Dispatch a Custom Event When Monaco is Ready:

    // src/components/MonacoEditor.tsx
    import { useEffect, useRef } from 'react';
    import * as monaco from 'monaco-editor';
    import { VimMode } from 'vim-monaco';
    import './MonacoEditor.css'; // Ensure this file exists and has the required styles
    
    interface MonacoEditorProps {
      initialValue: string;
      language: 'javascript' | 'typescript' | 'markdown';
      height?: string;
    }
    
    const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
      const editorRef = useRef<HTMLDivElement>(null

You're correct that declaring SelectionDirection inside the .then() scope will limit its availability to that scope. To make SelectionDirection available more broadly, you need to handle the asynchronous initialization properly.

Solution: Using Promises and Ensuring Monaco Initialization

Let's ensure that monaco is correctly initialized and available globally before any dependent code runs. We'll use a promise-based approach to achieve this.

Step 1: Create a Promise to Ensure Monaco is Available

First, let's declare the monacoReady promise and ensure it resolves once monaco is initialized.

Step 2: Modify MonacoEditor.tsx to Resolve the Promise

Here's the modified MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

// Create a promise to ensure monaco is available
const monacoReady = new Promise<void>((resolve) => {
  window.monacoReadyResolve = resolve;
});

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReadyResolve: () => void;
  }
}

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      // Ensure monaco is available globally
      window.monaco = monaco;
      window.monacoReadyResolve();
      console.log('window.monaco', window.monaco);

      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const vimMode = new VimMode(editor);
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;

Step 3: Modify adapter.ts to Use the Promise

In adapter.ts, wait for the monacoReady promise to resolve before accessing window.monaco.

Here's the modified adapter.ts:

// src/adapter.ts
import { IPosition, IRange, ISelection } from 'monaco-editor';
import { StatusBarInputOptions, ModeChangeEvent } from './statusbar';
import { ExCommandOptionalParameters } from './keymap_vim';
import { Pos, getEventKeyName, makePos } from './common';

console.log('CodeMirror adapter loaded', window);

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
  }
}

window.monacoReady.then(() => {
  const SelectionDirection = window.monaco.SelectionDirection;
  console.log('SelectionDirection:', SelectionDirection);

  class CmSelection {
    /// Where the selection started from
    readonly anchor: Pos;
    /// Where the cursor currently is
    readonly head: Pos;

    constructor(anchor: Pos, head: Pos) {
      this.anchor = anchor;
      this.head = head;
    }
  }

  // Export the class after monaco is ready
  (window as any).CmSelection = CmSelection;
}).catch(error => {
  console.error('Error waiting for monaco:', error);
});

Explanation

  1. Declare a Promise: In MonacoEditor.tsx, we declare a monacoReady promise and resolve it once monaco is initialized and assigned to window.monaco.
  2. Ensure Monaco is Set: We ensure that window.monaco is set before resolving the promise.
  3. Wait for the Promise: In adapter.ts, we wait for window.monacoReady to resolve before accessing window.monaco. This ensures that monaco is available before dependent code

To attach monacoReady to the window object, you need to declare it globally and ensure it's properly assigned. We will use TypeScript to declare the global properties and then set them in the appropriate places in your MonacoEditor.tsx.

Step-by-Step Solution

  1. Create a TypeScript Declaration File: Create a file named global.d.ts (if it doesn't already exist) to extend the Window interface with the necessary properties.

  2. Extend the Window Interface: Add the following code to global.d.ts:

    // src/global.d.ts
    import * as monaco from 'monaco-editor';
    
    declare global {
      interface Window {
        monaco: typeof monaco;
        monacoReady: Promise<void>;
        monacoReadyResolve: () => void;
      }
    }
  3. Initialize and Attach monacoReady to window: Modify your MonacoEditor.tsx to initialize and attach monacoReady to the window object.

Here's the complete MonacoEditor.tsx:

// src/components/MonacoEditor.tsx
import { useEffect, useRef } from 'react';
import * as monaco from 'monaco-editor';
import { VimMode } from 'vim-monaco';
import './MonacoEditor.css'; // Ensure this file exists and has the required styles

interface MonacoEditorProps {
  initialValue: string;
  language: 'javascript' | 'typescript' | 'markdown';
  height?: string;
}

// Create a promise to ensure monaco is available
const monacoReady = new Promise<void>((resolve) => {
  window.monacoReadyResolve = resolve;
});

declare global {
  interface Window {
    monaco: typeof monaco;
    monacoReady: Promise<void>;
    monacoReadyResolve: () => void;
  }
}

window.monacoReady = monacoReady;

const MonacoEditor: React.FC<MonacoEditorProps> = ({ initialValue, language, height = '400px' }) => {
  const editorRef = useRef<HTMLDivElement>(null);
  const editorInstanceRef = useRef<monaco.editor.IStandaloneCodeEditor | null>(null);

  useEffect(() => {
    if (editorRef.current) {
      const editor = monaco.editor.create(editorRef.current, {
        value: initialValue,
        language: language,
        theme: 'vs-dark',
        automaticLayout: true,
      });

      // Ensure monaco is available globally
      window.monaco = monaco;
      window.monacoReadyResolve();
      console.log('window.monaco', window.monaco);

      editorInstanceRef.current = editor;

      console.log('Monaco Editor created:', editor);

      // Ensure VimMode is loaded after editor creation
      try {
        const vimMode = new VimMode(editor);
        console.log('VimMode created:', vimMode);
      } catch (error) {
        console.error('Error initializing VimMode:', error);
      }

      return () => {
        if (editorInstanceRef.current) {
          editorInstanceRef.current.dispose();
        }
      };
    }
  }, [initialValue, language]);

  return (
    <div>
      <div ref={editorRef} className="monaco-editor-container" style={{ height }} />
      <div id="status" className="vim-status-bar"></div>
    </div>
  );
};

export default MonacoEditor;
  1. Modify adapter.ts to Use the Promise: In adapter.ts, wait for monacoReady to resolve before accessing window.monaco.

Here's the adapter.ts:

// src/adapter.ts
import { IPosition, IRange, ISelection } from 'monaco-editor';
