About
jogwheel gives you the power to take full control of your CSS keyframe animations via JavaScript.
- [x] separation of concerns: Declare animations with CSS
- [x] full control: Play, pause and scrub your animations
- [x] animation sequences: No brittle fiddling with animationEnd
- [ ] world peace
Install
jogwheel is available on npm.
npm install --save jogwheel
Usage
:warning: Please note jogwheel assumes Element.prototype.animate
is defined and returns a valid WebAnimationPlayer instance.
To achieve this you will have to include a WebAnimation polyfill, web-animations-js by Google is recommended.
The usage examples show recommended ways to include the polyfill.
CommonJS
jogwheel exposes its API as CommonJS module. Using the export and bundling your JavaScript with browserify, webpack or rollup is recommended.
// import the polyfill
import 'web-animations-js';
// import jogwheel
import jogwheel from 'jogwheel';
// Select target element
const element = document.querySelector('[data-animated]');
// Construct jogwheel instance from element
const player = jogwheel.create(element);
// Jump halfway into the animation
player.seek(0.5);
CDN
jogwheel provides prebundled downloads via wzrd.in.
Either embed or download the standalone bundle. Given you do not use a module system the standalone build will pollute window.jogwheel
. This usage is viable but not recommended.
Fast track example
# Install cross-platform opn command
npm install -g opn-cli
# Download example
curl -L https://git.io/vreEP > jogwheel-example.html
# Open example in default browser
opn jogwheel-example.html

Development
You dig jogwheel and want to submit a pull request? Awesome! Be sure to read the contribution guide and you should be good to go. Here are some notes to get you coding real quick.
# Clone repository, cd into it
git clone https://github.com/marionebl/jogwheel.git
cd jogwheel
# Install npm dependencies
npm install
# Start the default build/watch task
npm start
This will watch all files in source
and start the appropriate tasks when changes are detected.
Roadmap
jogwheel is up to a lot of good. This includes but is not limited to
- [x] super-awesome cross-browser tests
- [ ] unit-tested documentation code examples, because rust isn't the only language that can do cool dev convenience stuff
- [ ] an interactive playground and animation editor
- [ ] a plug-and-play react integration component
See Roadmap for details.
