animore

Animore makes DOM state transitions easier It uses internally the MutationObserver API to determinate whether a DOM node should be transitioned to a different state. It was inspired by riot-animore and works thanks to the flip technique by Paul Lewis

Demos

• the box
• the list
• textarea

Installation

Via npm

$ npm i animore -S

Script import

Via <script>

<script src="path/to/animore.js"></script>

Via ES2015 modules

import animore from 'animore'

Via commonjs

const animore = require('animore')

Usage

Simple automatic transitions

You can pass a query or a DOM node to animore and it will start watching its changes through a MutationObserver to trigger automatically the transitions.

const anima = animore('.my-div')[0] // animore returns always an array!

anima.el.style.marginTop = '300px'
// animore will autimatically detect this change and transition the y position of the `div`

Manual transitions

You can temporary freeze the watcher to trigger manually multiple transitions at same time:

const anima = animore('.my-div')[0]

anima.freeze()
anima.el.style.marginTop = '300px'
anima.el.style.marginLeft = '500px'
anima.unfreze().apply()
// animore will autimatically detect this change and transition the y position of the `div`

Options

The animore factory function accepts 2 arguments animore(el, options) with the options object you can specify how your animations should behave:

animore(myDiv, {
  duration: 300, // animation duration in ms
  easing: 'ease-in-out', // this should be a valid css easing function
  delay: 20, // animation delay
  onStart: function() { console.log('new animation started ')},
  onCancel: function() { console.log('animation canceled ')},
  onEnd: function() { console.log('animation ended ')}
})

API

Any animore function will return an object with the following properties

animore.destroy

Remove the DOM events disconnecting the MutationObserver internally created

@returns self

animore.apply

Apply manually an animation comparing the current DOM node state with its previous state

@returns self

animore.freeze

Freeze temporarily all the MutationObserver automatic updates

@returns self

animore.unfreeze

Re enable again the automatic transitions updates

@returns self

animore.el

Reference to the DOM node observed

@returns HTMLElement
