Tiny Javascript tweening engine.
Step 1:
npm install --save weeee.js
Step 2:
import Weeee from 'weeee.js';
const example = new Weeee({
// <time in ms>
// Infinity
duration: 1000,
// <time in ms>
delay: 0,
// Weeee.easeLinear
// Weeee.easeInCubic
// Weeee.easeOutCubic
// Weeee.easeInExpo
// Weeee.easeOutExpo
// Weeee.easeInElastic
// Weeee.easeOutElastic
// <any other f(x), which returns values from 0 to 1>
easing: Weeee.easeLinear,
// Weeee.normal
// Weeee.reverse
// Weeee.alternate
direction: Weeee.normal,
// true
// false
autoplay: true,
// false
// <number of iterations>
// Infinity
loop: false,
// <time in ms>
loopDelay: 0,
// <number from 1 to 60>
fps: 60,
// <function(progress, details)>
//
// Weeee doesn't force us to manipulate with specific CSS, SVG,
// Canvas or WebGL objects. Just do whatever you want here.
//
// Progress will be from 0 to 1.
//
// Additional details include:
// - startTime (when animation has been started, in ms)
// - currentTime (current time, may bee needed in infinite animations, in ms)
// - delta (time from the start, "currentTime - startTime", in ms)
// - isFinished (becomes true in the last frame of the finite animation)
func: (progress, details) => {
myElement.style.transform = `scale(${progress})`;
},
// Optional callback. It will be executed after the last frame of the animation.
callback: () => {
console.log('weeee!');
}
});
// Also it's possible to start/stop/restart it manually. Callback will NOT be executed.
//
// example.start();
// example.stop();
// example.restart();
It's possible to import Weeee right from the unpkg:
import Weeee from 'https://unpkg.com/weeee.js/weeee.js';
