Before you deploy, run through this polishing checklist so your React app is production-ready.
A Final Polishing Checklist Before Deploying a React App
Before you deploy, run through this polishing checklist so your React app is production-ready.
Loading and Error States
Every fetch shows a loading state and handles errors. No blank screens anywhere in the app.
Responsive Check
Test on mobile, tablet, and desktop. Use real devices or accurate emulators, not just browser resizing.
Form Validation
All forms validate input and show clear errors. Submit buttons are disabled or show feedback during submission.
Authentication
Signup, signin, signout, and protected routes all work. Authorized domains are configured in the auth provider.
SEO Basics
Set a meaningful title and meta description. For public content, ensure it can be crawled. Add Open Graph tags for sharing.
Performance
Check the bundle size, lazy-load heavy routes, and optimize images. The first load should be reasonably fast.
Accessibility
Buttons have accessible names, modals trap focus, images have alt text, and color contrast is sufficient. Use role-based queries.
Environment Variables
All secrets and config are in environment variables, not in code. Production variables are set in the hosting dashboard.
The Takeaway
Before deploying, polish loading and error states, responsive behavior, form validation, auth, SEO, performance, accessibility, and environment variables. This is the difference between a toy app and a production one.
Loading and error states on every fetch, responsive behavior on mobile and desktop, form validation, authentication, SEO basics, performance and bundle size, accessibility, and that environment variables are set and not in code.
Because many users will visit on mobile. Test on real devices or accurate emulators, not just browser resizing, which can hide real responsive issues. An app that only works on desktop loses a large share of users.
A meaningful title and meta description, Open Graph tags for sharing, and for public content, ensure it can be crawled. For client-side rendering, consider server rendering or pre-rendering for SEO-critical pages.
Buttons have accessible names, modals trap focus, images have alt text, color contrast is sufficient, and interactive elements are keyboard accessible. Use role-based queries when testing to mirror real assistive tech.
Because secrets and config should never be in code. All secrets and environment-specific config should be in environment variables, with production variables set in the hosting dashboard. Committing secrets is a security risk.
