Use virtual-dom with abstract-state-router!
example
index.js
var StateRouter = require('abstract-state-router')
var virtualdomRenderer = require('virtualdom-state-renderer')
var domready = require('domready')
var stateRouter = StateRouter(virtualdomRenderer, 'body')
// add whatever states to the state router
stateRouter.addState({
name: 'app',
route: '/',
template: require('./template.js')
})
domready(function() {
stateRouter.evaluateCurrentRoute('app')
})
template.js
module.exports = function template(h, resolveContent, helpers) {
return (
h('div', [
h('p', 'Pretty sweet, isn\'t it?'),
h('p', 'Here, let me give some examples or something.')
])
)
}
api
var virtualdomRenderer = require('virtualdom-state-renderer')
virtualdomRenderer
Pass this object into the StateRouter
.
var Router = require('abstract-state-router')
var renderer = require('virtualdom-state-renderer')
Router(renderer, 'body')
templates
A template is a function that returns a virtual-dom
object. If you wanted, you could use the virtual-html
library to generate a virtual-dom
object.
The function is supplied with these arguments:
h
is a function that returns avirtual-dom
node. View API here.resolveContent
is the resolve content, which is the set in the resolve callback. See theresolve()
function docs.helpers
is an object with the following properties:var active = isActive(stateName, parameters)
is a reference tostateRouter.stateIsActive(stateName, parameters)
. Returnstrue
orfalse
.var class = active(stateName, parameters)
is an abstraction tostateRouter.stateisActive(stateName, parameters)
. Returns'active'
or''
.var url = makePath(stateName, parameters)
is a reference tostateRouter.makePath(stateName, parameters)
. This function returns a URL for the given state and parameters.killEvent(ev)
is a function that doesev.preventDefault()
andev.stopPropagation()
.emitter
is the event emitter that is on thedomApi
. This allows a bit of communication between the template's DOM events (e.g. a mouse-click), and theactivate()
function.
template.js
var virtualHtml = require('virtual-html')
module.exports = function template(h, resolveContent, helpers) {
var html = (
'<div>' +
'<p>Pretty sweet, isn\'t it?</p>' +
'<p>Here, let me give some examples or something.</p>' +
'<a href="' + helpers.makePath('app') + '">' +
'Click to go to the "app" state.' +
'</a>' +
'</div>'
)
return virtualHtml(html)
}
domApi
This object is exposed by the state router in the activate()
function. The object has the following properties:
el
is the DOM element that is created/updated.emitter
is the event emitter onhelpers
. This allows the template to request an update, or something.sharedState
is the object that comes from the resolve content, which is the set in the resolve callback. See theresolve()
function docs.update()
is a function that will render the template, and update the DOM if necessary.
