DevProxy

Appearance

Use DevProxy with Next.js ​

Next.js works best when the dev server binds to 0.0.0.0 and DevProxy registers the port from the host OS.

Start the server ​

bash
pnpm dev --hostname 0.0.0.0 --port 3000

Or:

bash
npm run dev -- --hostname 0.0.0.0 --port 3000

Register with DevProxy ​

bash
devproxy add web.myapp --port 3000

This creates:

text
https://web.myapp.local -> 127.0.0.1:3000, localhost:3000

Set the public site URL ​

If the app generates absolute URLs, point it at the DevProxy domain:

text
NEXT_PUBLIC_SITE_URL=https://web.myapp.local

You can place that in .env.local.
