  2. Run automated checks.
  3. Build the application.
  4. Deploy the generated production assets.
  5. Configure the web server for the application routing strategy.
  6. Verify API URLs and environment configuration.
  7. Test the deployed application.

Deployment Checklist

  • Production build succeeds.
  • Environment values are correct.
  • Client-side routes work after refresh.
  • API requests use the correct backend.
  • Authentication works correctly.
  • Browser console has no unexpected errors.
  • Important pages work on mobile and desktop.
