Add per-PR preview deployment workflow

[pedropaulovc]

Testing per-PR deployment setup with Cloudflare Workers preview aliases.

Each PR will automatically deploy to: pr-<number>-vezza-dev.workers.dev

Setup required

Before this workflow will deploy:

1. Add CLOUDFLARE_API_TOKEN secret (create at https://dash.cloudflare.com/?to=/:account/api-tokens)
2. Add CLOUDFLARE_ACCOUNT_ID secret (find at https://dash.cloudflare.com/)

How it works

• PRs: Deploy to preview at pr-<number>-vezza-dev.workers.dev
• Push to main: Deploy to production
• Auto-comments on PRs with the preview URL

Pull request overview

Adds a GitHub Actions workflow to deploy Cloudflare Workers per pull request (using preview aliases) and deploy to production on pushes to main, with an automatic PR comment linking the preview URL.

Changes:

• Introduces .github/workflows/deploy-preview.yml to build and deploy PR previews via wrangler versions upload --preview-alias ...
• Deploys to production on push to main via cloudflare/wrangler-action@v3
• Posts a PR comment containing the preview URL for each PR run

Comments suppressed due to low confidence (2)

.github/workflows/deploy-preview.yml:48

• This workflow runs on every pull_request synchronize, so the createComment call will add a new comment on every push and can quickly spam the PR timeline. Consider upserting a single comment (e.g., search for an existing bot comment containing the preview URL and update it) instead of always creating a new one.

      - name: Comment PR with preview URL
        if: github.event_name == 'pull_request'
        uses: actions/github-script@v7
        with:
          script: |
            github.rest.issues.createComment({
              issue_number: context.issue.number,
              owner: context.repo.owner,
              repo: context.repo.repo,
              body: '🚀 Preview: https://pr-${{ github.event.number }}-vezza-dev.workers.dev'
            })

• Deploying on pull_request will run for forked PRs too, but GitHub does not provide repository secrets to workflows triggered from forks. That means the deploy step will fail noisily for external contributors. Add a guard (e.g., if: github.event.pull_request.head.repo.fork == false) or otherwise skip deploy/commenting when secrets aren't available.

      - name: Deploy PR Preview
        if: github.event_name == 'pull_request'
        uses: cloudflare/wrangler-action@v3
        with:
          apiToken: ${{ secrets.CLOUDFLARE_API_TOKEN }}
          accountId: ${{ secrets.CLOUDFLARE_ACCOUNT_ID }}
          command: versions upload --preview-alias pr-${{ github.event.number }}
