Why add an error boundary before deploying React?
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.

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 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.
