##Goals:
- templates are valid html
- updates only the parts of the dom that change
- async built in. filters and tags can be async without adding complexity
##install:
npm install altr
#Ussage:
this is still a work in progress so for now it needs to be used with browserify
js:
var altr = require('altr')
var el = document.getElementById('root')
, template = alter(el)
template.write({
name: "world"
, list: [1,2,3]
})
//later
template.write(new_state)
html:
<div id="root">
<h1>hello, {{ name }}!</h1>
<ul altr-for="item in list">
<li altr-value="item"></li>
</ul>
</div>
##Tags:
altr currently supports these tags: if, for, value, html, attr and more will be added soon
and can be used by adding an altr attribute to an element eg. <div altr-html="obj.my_html">
that element will now update its contents every time you write to the template.
##Values:
You can also insert values into text nodes or non altr-* attrubutes ussing the following syntax
{{ dot.path.to.value }}
##Filters:
I have only written and add filter so far, but the api is functional. {{ num|add(5) }}
Filters are through streams, so they can be used to do async stuff, or update values over time (eg. a countdown or transition)
