How to Prepare the DevTinder React UI for Deployment
Preparing the UI for deployment is the final step of a React build. Here is how to prepare the DevTinder React UI.
Run the Production Build
Run npm run build and fix any errors. The production build is what users get, so it must succeed with no warnings that matter.
Set Environment Variables
Set the production API URL, auth configuration, and any feature flags in the hosting dashboard. No secrets in code, and the right values per environment.
Configure SPA Routing
Configure the host to redirect all routes to index.html, so deep links work and React Router does not 404 in production.
Add an Error Boundary
Add an error boundary so an unhandled error shows a fallback instead of a blank screen for the user.
Handle All States
Confirm loading, error, and empty states are everywhere. A UI that breaks on slow networks or empty data looks unfinished in production.
Configure Authorized Auth Domains
In the auth provider, add the production domain to authorized domains. Otherwise auth redirects fail in production even though they work locally.
Test the Deployed UI
After deploy, click through the live UI on mobile and desktop, testing auth, forms, API calls, deep links, and real-time features. Catch production-only issues before users do.
The Takeaway
Prepare the DevTinder React UI for deployment by running the production build, setting environment variables, configuring SPA routing, adding an error boundary, handling all states, configuring authorized auth domains, and testing the deployed UI end to end.
Run the production build, set environment variables in the hosting dashboard, configure SPA routing so deep links work, add an error boundary, handle loading, error, and empty states, configure authorized auth domains, and test the deployed UI end to end.
Because the host serves 404 for routes that are not files, since routing is client-side. Configure the host to redirect all routes to index.html, so React Router loads and handles the route, and deep links work.
Because without one, an unhandled error in production shows a blank screen, which is a terrible experience. An error boundary wraps the app so errors show a fallback instead, letting users recover or report.
Because auth providers only allow redirects from authorized domains. Without adding your production domain, auth redirects fail in production even though they work on localhost. This is a common deploy bug.
Because production-only issues like wrong environment variables, unauthorized auth domains, and broken deep links only appear on the deployed app. Testing it catches these before users do, which is the point of preparing for deployment.
