Production Build
The production build is different from development mode. It performs optimizations, creates deployable output, and exposes issues that may not appear during development.
Always run a production build before deployment. Type errors, invalid imports, unsupported runtime APIs, and environment problems can surface during this stage.
Build and Start
npm run build
npm run start💡 The production build should be validated before the application is released.
Key Takeaways
- Test the production build before deploying.
- Do not assume development mode represents production behavior.
- Validate required environment variables during deployment.
