Deploying this React Router (BrowserRouter) app to Vercel without routing config causes 404s on any direct URL access or page refresh outside of
/, since Vercel tries to resolve routes as static files.Changes
vercel.json— adds a catch-all rewrite to serveindex.htmlfor all routes, letting React Router handle client-side navigation:{ "rewrites": [ { "source": "/(.*)", "destination": "/index.html" } ] }✨ Let Copilot coding agent set things up for you — coding agent works faster and does higher quality work when set up for your repo.
