Whether you are a hobbyist controlling an Arduino from your phone, a factory manager visualizing PLC data on a TV dashboard, or a healthcare integrator reading patient vitals from a serial monitor, offers the simplest, most secure, and most scalable path forward. serial. ws

Start building your bridge today. Your serial devices have waited long enough to join the web. Have you implemented a serial.ws solution? Share your use case in the comments below or contribute to open-source serial bridge projects on GitHub. Have you implemented a serial
// Native approach (without serial.ws) let port = await navigator.serial.requestPort(); await port.open( baudRate: 9600 ); This only works locally. You cannot share a serial device across a network or with multiple browser tabs. The serial.ws Bridge Solution This is where serial.ws enters. Instead of the browser talking directly to the OS, it talks to a WebSocket server (often running locally or on a network device). That server holds the actual serial connection.
// Forward serial data -> WebSocket clients port.on('data', (data) => ws.send(data.toString('utf8')); ); You cannot share a serial device across a
Run node bridge.js and open index.html . You now have a working system. Security Considerations for serial.ws Deployments While serial.ws is powerful, it introduces new attack surfaces. Here is how to secure it: Authentication and Authorization Never expose a raw serial.ws endpoint to the public internet without a token system. Use JSON Web Tokens (JWT) in the WebSocket handshake:
