API

This modules exports an object where every own property is an animation, except by the playAllfunction, and every animation is a function that returns a WebAnimation instance. Every animation has its own arguments, the only common argument is the element to which to apply the animation (always the first argument).

playAll(...animations, cb)

This function take some animations, play them all simultaneously, and when all of them has finished, runs a callback. For example,

var { playAll, moveDown, fadeOut } = require('animation-toolbox')
 
playAll(
  moveDown(el),
  fadeOut(el),
  () => {
    alert('animation finished')
  }
)

fade(el, from, to [, delay] [, cb])

Fade the opacity between from and to. Required arguments are el, the HtmlElement to animate, from, a value between 0 and 1, to a value between 0 and 1. Optional arguments are delay a number for the duration of the animation in miliseconds, defaults to 1000 (1s) and cb, a callback to run when the animtion finish, defaults to undefined.

fadeIn(el, [, delay] [, cb])

Runs the fade animation with from = 0 and to = 1.

fadeOut(el, [, delay] [, cb])

Runs the fade animation with from = 1 and to = 0.

move(el, axis, from, to [, delay] [, cb])

Translate el in some bidimensional axis ('x' or 'y') between from and to. Required arguments are el, the HTMLElement to animate, axis a string 'x' or 'y', from a string with the initial position to move, can be in any valid css unit for distance (eg. '100%', '20px') and to a string with the final position to move, can be in any valid css unit for distance (eg. '100%', '20px'). Optional arguments are delay a number for the duration of the animation in miliseconds, defaults to 1000 (1s) and cb, a callback to run when the animtion finish, defaults to undefined.

moveRight(el [, from] [, to] [, delay] [, cb])

Runs the move animation with axis = x. If from and to are not set, they default to '0%' and '100%' respectively.

moveDown(el [, from] [, to] [, delay] [, cb])

Runs the move animation with axis = y. If from and to are not set, they default to '0%' and '100%' respectively.

moveLeft(el [, from] [, to] [, delay] [, cb])

Runs the move animation with axis = x. If from and to are not set, they default to '0%' and '-100%' respectively, notice that whatever tovalue passed, is going to be forced to a negative value, so, for example, setting to move to = '35px' will actually move -35px in the x axis (35px to the left).

moveUp(el [, from] [, to] [, delay] [, cb])

Runs the move animation with axis = y. If from and to are not set, they default to '0%' and '-100%' respectively, notice that whatever tovalue passed, is going to be forced to a negative value, so, for example, setting to move to = '35px' will actually move -35px in the x axis (35px up).

bounce(el [, loop] [, cb])

Vertically bounce el three times. Optionally, you can pass a loop number to determine how many times should the element bounce, defaults to 3.

shake(el [, repeat] [, cb])

Horizontally shake an element. Set the repeat argument to true to shake forever.
