Create Internet of Things by Code!

f3.js stands for Form Follows Function() for JavaScript and is a web-based IDE for IoT applications. If you can write JavaScript, you can simultaneously define every aspect of the applications with the f3.js API - not only programs of microcontrollers and tiny computers but also physical layouts of enclosures of the devices.

Assemble and run the app

The f3.js API is provided as a Node.js module named f3js. You can specify which hardware modules to use (e.g. var Camera = require('jscam'); var c = new Camera()), how they behave (e.g. c.takePicture()), and where they are placed on laser-cut interfaces by code (e.g. var f3js = require('f3js'); f3js.add(c, 75, 35) opening holes for wires and screws to hold the module).

Even if you cannot write programs, you can customize IoT applications written by others through intuitive GUI such as sliders and checkboxes. The f3.js IDE tells you which components to purchase and how to print out the device enclosures, assemble the device, and install the programs. It is as easy as assembling plastic models!
