fui

This is an experimental library to experiment whether handling of events can neatly be abstracted away from the actual event handling code itself.

NPM

experimental

Example Code

Here is some example code:

var fui = require('fui');

fui()
  .up(function(context, target, x, y) {
    this.state.down = false;
  })
  .filter('canvas')
  .relative()
  .each(function(target) {
     this.args.unshift(target.getContext('2d'));
  })
  .down(function(context, target, x, y) {
    this.state.down = true;
    
    context.beginPath();
    context.moveTo(x, y);
  })
  .move(function(context, target, x, y) {
    if (this.lastTarget && target !== this.lastTarget) {
      context.moveTo(x, y);
    }
    else if (this.state.down) {
      context.lineTo(x, y);
      context.stroke();
    }
  });
