Phidget22 JavaScript Library

Official Phidget22 JavaScript library.

This library includes both Node.js and browser support.

Phidgets are accessed over the network via the Phidget Network Server.

Newer Phidgets can also be opened directly over USB, allowing for no-install access within the Browser or Node.js.

A smaller network only library is also available: phidget22-net

Start by reading the Phidgets JavaScript Language Page.
