Covers both Vercel's built-in Git integration and custom CI pipelines using the Vercel CLI. ## Prerequisites - GitHub repository with Actions enabled - Vercel project linked to the repo - `VERCEL_TOKEN` stored as GitHub Secret - `VERCEL_ORG_ID` and `VERCEL_PROJECT_ID` from `.vercel/project.json` ## Instructions ### Step 1: Store CI Secrets in GitHub ```bash # Get project and org IDs cat .vercel/project.json # {"orgId":"team_xxx","projectId":"prj_xxx"} # Add secrets to GitHub repo gh secret set VERCEL_TOKEN --body "your-vercel-token" gh secret set VERCEL_ORG_ID --body "team_xxx" gh secret set VERCEL_PROJECT_ID --body "prj_xxx" ``` ### Step 2: GitHub Actions — Preview on PR ```yaml # .github/workflows/vercel-preview.yml name: Vercel Preview Deployment on: pull_request: branches: [main] jobs: deploy-preview: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Install Vercel CLI run: npm install -g vercel@latest - name: Pull Vercel Environment run: vercel pull --yes --environment=preview --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - name: Build Project run: vercel build --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - name: Deploy Preview id: deploy run: | url=$(vercel deploy --prebuilt --token=${{ secrets.VERCEL_TOKEN }}) echo "preview_url=$url" >> $GITHUB_OUTPUT env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - name: Comment PR with Preview URL 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 deployed: ${{ steps.deploy.outputs.preview_url }}` }) ``` ### Step 3: GitHub Actions — Production on Merge ```yaml # .github/workflows/vercel-production.yml name: Vercel Production Deployment on: push: branches: [main] jobs: deploy-production: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - name: Install Vercel CLI run: npm install -g vercel@latest - name: Pull Vercel Environment run: vercel pull --yes --environment=production --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - name: Build Project run: vercel build --prod --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - name: Deploy Production run: vercel deploy --prebuilt --prod --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} ``` ### Step 4: Test Gating — Run Tests Before Deploy ```yaml # .github/workflows/vercel-gated.yml name: Gated Vercel Deploy on: push: branches: [main] jobs: test: runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - uses: actions/setup-node@v4 with: { node-version: 20 } - run: npm ci - run: npm test - run: npm run lint - run: npx tsc --noEmit deploy: needs: test # Only deploy if tests pass runs-on: ubuntu-latest steps: - uses: actions/checkout@v4 - run: npm install -g vercel@latest - run: vercel pull --yes --environment=production --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - run: vercel build --prod --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} - run: vercel deploy --prebuilt --prod --token=${{ secrets.VERCEL_TOKEN }} env: VERCEL_ORG_ID: ${{ secrets.VERCEL_ORG_ID }} VERCEL_PROJECT_ID: ${{ secrets.VERCEL_PROJECT_ID }} ``` ### Step 5: Skip Builds for Non-Code Changes ```json // vercel.json — skip build when only docs change { "ignoreCommand": "git diff HEAD^ HEAD --quiet -- . ':!docs' ':!*.md' ':!.github'" } ``` Or in the dashboard: **Settings > Git > Ignored Build Step** ### Step 6: Vercel's Built-In Git Integration (Alternative) If you prefer Vercel's automatic deployments over custom CI: 1. Connect your GitHub repo in the Vercel dashboard 2. Vercel auto-deploys: preview on every push, production on merge to main 3. Configure in **Settings > Git**: - Production branch: `main` - Preview branches: all other branches - Auto-assign custom domains to production This approach requires zero CI configuration but gives less control over test gating. ## Output - Preview deployments on every PR with URL comment - Production deployments on merge to main (after tests pass) - Test gating preventing broken code from reaching production - Build skip rules for documentation-only changes ## Error Handling | Error | Cause | Solution | |-------|-------|----------| | `Error: VERCEL_TOKEN is not set` | Secret not configured | Add `VERCEL_TOKEN` as GitHub repo secret | | `Error: Could not find project` | Wrong ORG_ID or PROJECT_ID | Check `.vercel/project.json` values | | `vercel pull` fails | Token lacks project access | Regenerate token with correct scope | | Preview not commenting on PR | Missing `actions/github-script` | Add the comment step with correct permissions | | Build cache not working | CI runs on fresh runner | Use `actions/cache` for `node_modules` and `.vercel/output` | ## Resources - [Vercel CLI in CI](https://vercel.com/docs/cli/deploying-from-cli) - [GitHub Actions](https://docs.github.com/en/actions) - [Vercel Git Integration](https://vercel.com/docs/deployments/git) - [Ignored Build Step](https://vercel.com/docs/project-configuration#ignorecommand) ## Next Steps For deployment orchestration, see `vercel-deploy-integration`.
