Auto-deploy every code push

In your repo, create .github/workflows/ci.yml. Add a workflow that triggers on push and pull_request, installs dependencies with npm ci, runs your test suite, and builds the project. Commit this file to see your first workflow run in the Actions tab.

Import your GitHub repository into Vercel. Configure the build command and output directory. Enable preview deployments so every branch automatically gets its own shareable URL before merging to production.

In Vercel, go to Settings → Integrations and install the Slack integration. Select the channel where deployment notifications should appear. You will receive a message every time a deployment succeeds or fails.
