DevProxy

Appearance

Use DevProxy with Express ​

Express applications work with DevProxy whether they run in WSL, Docker, or natively on Windows.

Start the server ​

Make sure the app listens on the expected port:

js
const PORT = process.env.PORT || 3000;
app.listen(PORT, "0.0.0.0", () => {
  console.log(`Server running on port ${PORT}`);
});

Start it:

bash
node server.js

Register with DevProxy ​

bash
devproxy add api.myapp --port 3000

This creates:

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

Optional proxy headers ​

If your app needs to know it is behind a reverse proxy:

js
app.set("trust proxy", true);
