After my previous experiments with the Web Serial API, I started experimenting with Svelte .

Within a couple of days I have created - the Web Serial Controller app.

The interface might seem familiar - it’s based on XP.css - a Windows XP CSS theme. It was inspired by some of the Serial hardware software used in the 00’s.

The interface of Web Serial Controller

The application is fully open source and features:

  • Fully connected state - use the screens or keyboard shortcuts to connect and disconnect from devices with shared state
  • Filter devices by vendor ID with a fully searchable list of all hardware vendors
  • A draggable interface XP-like interface
  • Options storage in localStorage
  • Send text messages to any connected device
