How to use it
mithril-transition is a function factory that returns an object with an oncreate and onremove hooks to add in the vnode lifecycle (where you want animate it) of mithril.
Check our live example
Functions
createTransition(options = {}) -> {transition}
Factory function to create a new transition. The options are defined below.
transition.oncreate(vnode)
Function that you need hook up to the lifecycle of the vnode
transition.onremove(vnode)
Function that you need hook up to the lifecycle of the vnode
transition.enable()
Method to enable the animation. By default is enabled.
transition.disable()
Method to disable the animation.
Options
animation (required)
Callback function where you define the animation for the next/prev component.
The callback has an object argument {} with the next properties:
lastElm: The last DOM element that is removing.
nextElm: The new DOM element that is inserting.
direction: This option allow to you define differents animations based of next/prev direction of the lifecycle components. Is required have at least useHistory in true.
cbLast: Callback to complete the remove of the lastElm. (is required call it)
cbNext: Callback to complete the insert of the nextElm. (is required call it)
useHistory (default = true)
When is enabled the library keep the history of your components, to know if the next element in the transition is really the next element or a prev element.
persistHistoryAs ({string} default = null)
Save the history in the sessionStorage identified by a key.
classList ({object})
Before that the transition begin, the library set a list of classes for each parent|element and remove it when the transition is finished.
default = {
parent: 'm-transition-parent',
lastElem: 'm-transition-last-element',
newElem: 'm-transition-next-element',
direction: 'm-transition-<direction>'
}
On roadmap
- Add unit tests
