    A utility panel to make working with Greensock Animation Platform timeline animations easier.


    AnimPanel simplifies the process of building complex timeline-based animations using the Greensock Animation Platform by adding a handful of extremely useful debugging tools, including:

    • Play, Pause, and Restart buttons
    • A visual playback scrubber
    • Buttons to dynamically change the playback speed (1x, 0.5x, 0.2x, etc)
    • A display of the current timeline time
    • For TimelineMax timelines, automatically-added buttons to jump to each label in the timeline
    • The ability to easily set custom loop in and out ranges for focusing on a specific span of the overall timeline, including making these in/out points persistent between page refreshes
    • Keyboard shortcuts for common actions

    You can install AnimPanel via npm:

    npm install anim-panel --save

    or simply include it in your HTML:

    <script src="anim_panel.js"></script>


    // Require the module if you're using something like browserify or webpack
    var AnimPanel = require('anim-panel')
    // Create your Greensock timeline using TimelineLite or TimelineMax
    // (using TimelineMax gets you extra goodies like label buttons)
    var tl = new TimelineMax({});
    // Add some stuff to your timeline (see the gsap docs if you don't know how to do this)
    // Create the AnimPanel, passing it your Timeline instance
    new AnimPanel(tl);

    Customizing Shortcuts

    new AnimPanel(tl, {
      shortcuts: {
        togglePlay: 'tab',
        setRangeStart: 'i',
        setRangeEnd: 'o'
