A node.js and client-side library for (quadratic and cubic) Bezier curve work.
For a Demo and the API, hit up either pomax.github.io/bezierjs
or read the souce (./lib for the library code, start at index.js).
npm install bezier-js will add bezier.js to your dependencies, remember to add --save or --save-dev if you need that to be persistent of course.
var Bezier = require('bezier-js') and off you go.
Load the toplevel bezier.js the same way you would any other browser script, using a <script src="..."></script> declaration.
To test new code, use npm test.
To build the library, use npm run build.
