Question: How to proxy requests in production?

I feel like an idiot…

I have create-react-app and a Rails 5 API. All requests should hit the rails server, and I was able to use the proxy feature in package.json, which is awesome!

"proxy": "http://localhost:3001"

But how do I do this in production? In production my rails server can’t live at the same domain as my create-react-app right, unless I am missing something?

Thanks for your help.

@patwalls hi! You need to set this up yourself; most likely on the rails side. You can make rails serve the static assets so they’re on the same domain, or you can prefix all of your api calls with the API-server URL and control it via an env var (/ in dev, http://api.example.com/ in production).

Even if rails only serves the index.html, you can configure the production build to reference a CDN/different url. Checkout the PUBLIC_URL env var.

Make I an environment variable something like process.env.REACT_APP_API_DOMAIN. Make sure it is set when you build (Netfliy let’s you set env vars, of building locally can use cross-env or dotenv
