GitHub Actions Workflows

This repo uses GitHub Actions for site deployment, worker deployment, code scanning, and contributor onboarding.

Workflow	File	When it runs	How to use it
Deploy VitePress site	.github/workflows/deploy.yml	Pushes to main except worker/**, or manual dispatch	Push site/content changes to main to deploy automatically. You can also run it manually from the Actions tab.
Deploy Cloudflare Worker	.github/workflows/deploy-worker.yml	Pushes that touch worker/**, or manual dispatch	Make worker-only changes under worker/ and push to main, or run it manually from the Actions tab. Requires Cloudflare secrets to be configured.
CodeQL Analysis	.github/workflows/codeql.yml	Pushes to main, pull requests to main, and weekly schedule	Open a PR or push to main to trigger scanning automatically. Use it to catch JavaScript security and quality issues.
Welcome First Timers	.github/workflows/first-interaction.yml	First issue opened or first pull request opened	No manual action needed. It automatically posts a welcome comment for first-time contributors.

Maintainer Notes

• Run npm run docs:build locally before pushing site/content changes.
• The worker workflow requires:
  • CLOUDFLARE_API_TOKEN
  • CLOUDFLARE_ACCOUNT_ID
• The site deploy workflow publishes the built VitePress output to GitHub Pages.
• The worker deploy workflow is isolated from normal site deploys because deploy.yml ignores worker/** changes.

Typical Usage

1. Updating notes or docs pages Push your changes to main. The site deploy workflow runs automatically.

2. Updating only the Cloudflare Worker Change files under worker/ and push to main. The worker deploy workflow runs automatically.

3. Re-running a workflow without a new commit Open the repository’s Actions tab in GitHub and use Run workflow for any workflow that supports workflow_dispatch.
