Ratchet - CSS3 Transform Parser & Manipulator

Ratchet assists with the process of dissecting CSS3 transform strings into
javascript objects that you can then do something more intelligent with.


 

Example Usage

Displayed below is a simple example. First a html file with a div element
styled to look like a square box:

``html









`

And then some JS that can be used to manipulate the transform of the box (
in partnership with the feature
module):

`js
const ratchet = require('..');
const transform = require('feature/css')('transform');

const box = document.getElementById('box');
const { width: boxWidth } = box.getBoundingClientRect();
const t = transform && ratchet(transform(box));

if (t) {
let forwards = true;

// this is all a bit hacky, but you get the idea
const animate = () => {
if (forwards) {
t.translate.x.value += 2;
t.rotate.z.value += 5;
forwards = forwards && t.translate.x.value + boxWidth < window.innerWidth;
} else {
t.translate.x.value -= 2;
t.rotate.z.value -= 5;
forwards = t.translate.x.value < 0;
}

transform(box, t.toString());
window.requestAnimationFrame(animate);
};

animate();
}
`

If you want to give this a go you should be able to run the example with
bde simply type yarn example`
in the repository once cloned an dependencies have been installed.

Assuming it is working, you will see a square red box, moving
and rotating towards the right of the screen.
