The GitHub Pages deployment was showing a blank page because the GitHub Actions workflow was running two conflicting build commands that overwrote each other.

Issue

The deployed page appeared blank with no CSS or JavaScript loading, as shown in the issue screenshot. Users would see only black text on a white background with no styling.

Root Cause

The GitHub Actions workflow in .github/workflows/deploy-to-pages.yml was running two build commands:

  1. npm run build:pages - Creates correct GitHub Pages build with relative paths (base: './')
  2. npm run build - Overwrites it with regular build using absolute paths (base: '/github-copilot-usage/')

The second build would overwrite the GitHub Pages optimized build, resulting in incorrect asset paths that failed to load on GitHub Pages.

Solution

Removed the duplicate npm run build step from the GitHub Actions workflow. Now only npm run build:pages runs, which:

  • Uses vite.github-pages.config.ts with base: './' for relative paths
  • Excludes @github/spark dependencies that aren't available in GitHub Pages
  • Generates correct index.html with relative asset references like ./assets/index-XXX.js

Verification

  • ✅ Build generates correct relative asset paths
  • ✅ No absolute path references that would fail on GitHub Pages
  • ✅ CSS and JavaScript files are properly bundled and referenced
  • ✅ Minimal change (only 3 lines removed from workflow)

Fixes #12.

I can confirm the build configuration is working correctly locally - it generates relative paths (./assets/index-XXX.css) as expected. Since you mentioned the issue persists after merging #10, this appears to be a caching issue.

The GitHub Pages deployment may be serving a cached version. Try:

  1. Re-triggering the GitHub Actions workflow manually from the Actions tab
  2. Making a small commit to force a fresh deployment
  3. Checking if GitHub Pages is configured to deploy from the correct branch (main)

The workflow at commit 55069ca should generate the correct relative paths.

lets temporarily deploy from any branch, so we can test. Comment out the if statement that blocks the deploy from another branch then main

Done! I've commented out the if statement that restricts deployment to main branch. The workflow will now deploy from any branch for testing purposes. See commit 4e30c94.
