I have this file src/index.ts that is supposed to load a set of commands into a CommandRegistry

import { commandRegistry } from './commandRegistry';
import { clearCommand } from './ClearCommand';
import { ListPhrasesCommand } from "./ListPhrasesCommand";

commandRegistry.register(clearCommand);
commandRegistry.register(ListPhrasesCommand);

// src/commands/commandRegistry.ts

import { ICommand } from './ICommand';

class CommandRegistry {
  private commands: Record<string, ICommand> = {};

  register(command: ICommand) {
    this.commands[command.name] = command;
  }

  getCommand(name: string): ICommand | undefined {
    return this.commands[name];
  }

  getHelp(filter?: string): string {
    return Object.values(this.commands)
      .filter(cmd => !filter || cmd.name.includes(filter))
      .map(cmd => `${cmd.name}: ${cmd.description}`)
      .join('\n\n');
  }

}

export const commandRegistry = new CommandRegistry();

But I am not sure where to call it from in the application.

I think I am just supposed to import src/commads somewhere and it finds the index.ts, but I am not sure.

In a Vite React TypeScript project, you would typically import the module that registers your commands in a central place in your application, such as your main entry point file or the main app component. In your case, since src/index.ts is responsible for registering commands to the CommandRegistry, you should import it in the entry point of your React application, which is often src/main.tsx or src/index.tsx.

Here's an example of how you might import src/index.ts:

// src/main.tsx or src/index.tsx
import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './index.ts'; // Import the file that registers the commands

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
);

By importing src/index.ts, you ensure that the commands are registered before the app is rendered. Since the commandRegistry is likely to be used throughout your application, it's important to have it populated with all necessary commands early on.

This import only needs to be done once, and the place where it is done should be the entry point of your application, where the root component is rendered. The commandRegistry instance will then be available for use throughout your app due to its export from commandRegistry.ts.

I mispoke. The file is src/commands/index.ts

// src/commands/index.ts

import { commandRegistry } from './commandRegistry';
import { clearCommand } from './ClearCommand';
import { ListPhrasesCommand } from "./ListPhrasesCommand";

commandRegistry.register(clearCommand);
commandRegistry.register(ListPhrasesCommand);

Thank you for the clarification. In that case, you would import src/commands/index.ts in a similar way to ensure the commands are registered at the start of your application. You should import this module in your main entry point file, which is typically src/main.tsx or src/index.tsx. Here's how you can do it:

// src/main.tsx or src/index.tsx
import React from 'react';
import ReactDOM from 'react-dom/client';
import App from './App';
import './commands'; // Import the commands module to register the commands

ReactDOM.createRoot(document.getElementById('root')!).render(
  <React.StrictMode>
    <App />
  </React.StrictMode>,
);

By importing the src/commands module, you're effectively running the code inside src/commands/index.ts, which registers your commands. This should happen before your React app is rendered so that the command registry is populated and ready to be used throughout the application.
