Start the Remix development server and the Bun application server by running:
bun run dev
This starts your app in development mode, performing HMR both on the server and in the browser when Remix rebuilds assets so you don't need a process manager restarting the express server.
First, build your app for production:
bun run build
Then run the app in production mode:
bun run start
Now you'll need to pick a host to deploy it to.
