How can I publish this Vite React app as a static app on GitHub Pages using the existing GH repository that it's in?

I think I can just add a .github/workflows/ file and run some gh command lines, right?

To publish your Vite React app as a static app on GitHub Pages, you need to set up a GitHub Actions workflow and configure your project to output the build to a specific branch (usually gh-pages). Here's a step-by-step guide:

  1. Configure Vite for GitHub Pages: Ensure your vite.config.js (or vite.config.ts if using TypeScript) has the correct base path set for GitHub Pages, which is typically the repository name prefixed by a slash.

    // vite.config.js or vite.config.ts
    export default defineConfig({
      base: '/<repository-name>/',
      // ... other configurations
    });
  2. Create GitHub Actions Workflow:

    • Navigate to your GitHub repository and create a new workflow file in the following path: .github/workflows/deploy.yml.
    name: Build and Deploy to GitHub Pages
    on:
      push:
        branches:
          - main  # Set this to your default branch
    
    jobs:
      build-and-deploy:
        runs-on: ubuntu-latest
        steps:
          - uses: actions/checkout@v2
    
          - name: Setup Node.js
            uses: actions/setup-node@v2
            with:
              node-version: '14'  # Set this to the node version you prefer
    
          - name: Install dependencies
            run: npm install  # or use yarn
    
          - name: Build
            run: npm run build  # or use yarn
    
          - name: Deploy to GitHub Pages
            uses: peaceiris/actions-gh-pages@v3
            with:
              github_token: ${{ secrets.GITHUB_TOKEN }}
              publish_dir: ./dist  # Set this to the output directory of Vite build
  3. Update Package Scripts: Add a predeploy and deploy script to your package.json to build the project and push it to the gh-pages branch. The gh-pages package can be used for this.

    {
      "scripts": {
        "predeploy": "npm run build",
        "deploy": "gh-pages -d dist"  // Replace 'dist' with your build output directory
      }
    }
  4. Commit Workflow File: Commit the .github/workflows/deploy.yml file to your repository.

  5. Push to GitHub: Push your changes to the repository. The GitHub Actions workflow will automatically run and deploy your app to GitHub Pages.

After setting this up, every push to the main branch (or your default branch) will trigger the GitHub Actions workflow, build your app, and deploy it to GitHub Pages.

Please note that, in this setup, the peaceiris/actions-gh-pages@v3 action is used to deploy the build artifacts, so you don't need to run the gh-pages command line manually. The action handles the deployment process for you.

Should predeploy = vite build?


Codeium at 12:04 pm, May 27, 2024

In the context of a Vite project, you would indeed use vite build to create a production build of your app. If you are setting up scripts in your package.json, you will typically have a build script that runs vite build. Here's how you would set up your package.json scripts:

{
  "scripts": {
    "build": "vite build",
    "predeploy": "npm run build",
    "deploy": "gh-pages -d dist"
  }
}

The predeploy script is a convenience that makes sure the build script is run automatically before deploy when you run npm run deploy. Since the build script already runs vite build, you don't need to specify vite build again in predeploy; you can just call npm run build.

However, for the GitHub Actions workflow, you don't need to rely on the predeploy or deploy scripts. The workflow will directly run the build command and use the action peaceiris/actions-gh-pages@v3 to deploy to GitHub Pages. So the relevant part of your workflow file will look like this:

- name: Install dependencies
  run: npm install  # or use yarn if you prefer

- name: Build
  run: npm run build  # This will run the "build" script, which in turn runs "vite build"

- name: Deploy to GitHub Pages
  uses: peaceiris/actions-gh-pages@v3
  with:
    github_token: ${{ secrets.GITHUB_TOKEN }}
    publish_dir: ./dist  # Replace with your Vite project's build output directory

The deploy.yml file in your .github/workflows directory will handle the entire process on GitHub's servers when you push changes to your repository.

My repo looks like this, so what should I set as the base in the vite.config.ts?

Given your repository URL https://github.com/InTEGr8or/handex-react, the base in your vite.config.ts should be set to the repository name with a leading slash. For your repository, it should be /handex-react/. Here's how you should set it:

import { defineConfig } from 'vite'
import react from '@vitejs/plugin-react'

// https://vitejs.dev/config/
export default defineConfig({
  plugins: [react()],
  base: '/handex-react/'
})

This will ensure that Vite correctly references the resources relative to the base URL of your GitHub Pages site.

now, the images don't work.

They were in http://localhost:5173/images/svgs/9.svg


Codeium at 12:42 pm, May 27, 2024

If the images are not loading after deployment, it's likely because the paths to the images are not correct for the GitHub Pages environment. You need to make sure the paths are relative to the base you set in your vite.config.ts.

Assuming you have set the base in your vite.config.ts correctly as /handex-react/, and your images are located in the public/images/svgs directory of your project, you can reference them in your code like this:

<img src="/handex-react/images/svgs/9.svg" alt="description" />

However, if you want to avoid hardcoding the base path, you can use the import.meta.env.BASE_URL variable provided by Vite, which automatically includes the base path.

Here is an example of how to use it:

<img src={`${import.meta.env.BASE_URL}images/svgs/9.svg`} alt="description" />

Vite will replace import.meta.env.BASE_URL with the correct base path during the build process, ensuring that your assets point to the correct URLs on both your local development server and the GitHub Pages environment. Make sure to move your images into the public folder if they are not already there, as Vite will copy the contents of the public folder to the root of the build output directory (dist by default).

Remember to check the network tab in your browser's developer tools to see if there are any 404 errors when trying to load the images, which can help you diagnose path issues.

OK, I currently have this in the ErrorDisplay.tsx

 return (
  <div style={{ display: props.isVisible ? 'block' : 'none'}} >
   <div>Error Count: {errorCount}</div>
   <div className="chord-image-holder" id="chord-image-holder" data-source="ErrorDisplay.tsx">
    <div className="col-sm-2 row generated next" id="chord2" >
     <span id="char15">{mismatchedChar}</span>
     <img loading="lazy" alt="2" src={`/images/svgs/${mismatchedCharCode}.svg`} width="100" className="hand"></img>
    </div></div>
  </div>
 );

Codeium at 12:44 pm, May 27, 2024

To make sure the image paths work both locally and on GitHub Pages after setting the base in vite.config.ts, you should update the src attribute of the img tag to include the import.meta.env.BASE_URL as follows:

return (
  <div style={{ display: props.isVisible ? 'block' : 'none'}} >
    <div>Error Count: {errorCount}</div>
    <div className="chord-image-holder" id="chord-image-holder" data-source="ErrorDisplay.tsx">
      <div className="col-sm-2 row generated next" id="chord2" >
        <span id="char15">{mismatchedChar}</span>
        <img loading="lazy" alt="2" src={`${import.meta.env.BASE_URL}images/svgs/${mismatchedCharCode}.svg`} width="100" className="hand"></img>
      </div>
    </div>
  </div>
);

The import.meta.env.BASE_URL will be replaced with the correct base path during the build process, so it will point to /handex-react/ when deployed on GitHub Pages, and it will be / when you are running your Vite dev server locally. This allows your image paths to be correct in both development and production environments.

I see. That works.


Codeium at 12:44 pm, May 27, 2024

Great! I'm glad to hear that it works. If you have any more questions or need further assistance with your Vite React TypeScript project or anything else, feel free to ask. Good luck with your development!
