Comprehensive overview of adding book transitions.

transition.js

enyo.Book.transition({
	//Name of the transition:
	name: "everything",
	//Using this will set up the step function, automatically transitioning between values.
	//If you don't set this as true, you're expected to provide your own step function.
	auto: true,
	//Set it up to use next/back animations.
	directional: true,
	//Set the easing function. The default is enyo.easing.quadInOut. You can also define your own easing function here.
	easing: enyo.easing.quadInOut,
	//Set up properties about the transition itself:
	transition: {
		//The duration, in ms, of the transition:
		duration: 500,
		next: {
			//Some animations use different in/out transitions, so you can define them here.
			//The book will automagically transition numerical values.
			from: {
				opacity: 0,
				transform: {

			visible: {

				transform: {
					scale: 1
				}
			},
			out: {
				opacity: 0,
				transform: {

			//NOTE: If your "from" and "out" are the same, you can just give the property "hidden" the values.

		back: {
			//You get the idea.
