You can use a proxy server to replace local development server port numbers with named .localhost domains. This approach routes traffic from stable URLs like http://myapp.localhost directly to your local Node.js processes, eliminating port conflicts and making addresses memorable.
EADDRINUSE errors happen when multiple local development servers compete for the same port numbers. A proxy tool resolves this by automatically assigning free ports to each Node.js framework and managing the routing, preventing cross-application conflicts in monorepos.
Install the proxy globally via npm install -g portless, then run portless proxy start. Once active, you can start your Node.js frameworks with commands like portless api.myapp and portless frontend.myapp to access each microservice at its own .localhost domain.
Most Node.js frameworks work without special configuration because the proxy respects the PORT environment variable. The proxy intercepts traffic at the named .localhost domain and routes it to the dynamically assigned port your framework uses.
Yes, local development proxies can optionally support HTTPS and HTTP/2 by automatically generating certificates. This allows your named .localhost domains to securely mirror production environments during local development.
