htmlcomponent

A microlib that empowers you to reference a component in HTML.
It does this by a common way to mark the components and with an interface to pass the dom and some options directly from HTML to JS.
The basic function syntax works by default with multiple instances of one component.
HTMLComponent Spec without the need to drop browser support.
So no more .js--slider-top referencing in your HTML.

Basic Usage

<div data-hc="app/main">just html</div>

<script src="htmlcomponent.min.js"></script>
<script>
	var components = {};
	components["app/main"] = function(dom, opts) {
		dom.innerHTML = "simple component";
	};
	htmlcomponent.setStaticLoader(components);
	htmlcomponent.query(document);
</script>

Result will be:

<div data-hci="app/main">simple component</div>

Usage with Options

<div data-hc="app/mainopts" data-hcd='{"name": "SuperComponent"}'>just html</div>

<script src="htmlcomponent.min.js"></script>
<script>
	var components = {};
	components["app/mainopts"] = function(dom, opts) {
		dom.innerHTML = "my name is "+opts.name;
	};
	htmlcomponent.setStaticLoader(components);
	htmlcomponent.query(document);
</script>

Result will be:

<div data-hci="app/mainopts">my name is SuperComponent</div>

Usage with options as a json script

<div data-hc="app/mainopts">
	<script type="application/json" data-hc>
		{
			"name": "SuperComponent",
			"bigdata": [
				1,
				2,
				3 //you get it
			]
		}
	</script>
	just html
</div>

<script src="htmlcomponent.min.js"></script>
<script>
	var components = {};
	components["app/mainopts"] = function(dom, opts) {
		dom.innerHTML = "my name is "+opts.name;
	};
	htmlcomponent.setStaticLoader(components);
	htmlcomponent.query(document);
</script>

Usage with SystemJS or any other promise based loader

<div data-hc="app/main">
	just html
</div>

<script src="system.js">
<script src="config.js">
<script src="htmlcomponent.min.js"></script>
<script>
	//this is the default behavior so the next line is optional
	htmlcomponent.config.promiseLoader = System.import.bind(System)
	htmlcomponent.query(document);
</script>

//main.js amdstlye
define(function() {
	return function(dom, opts) {
		dom.innerHTML = "my name is "+opts.name;
	}
});

Use in a build/integration environment

It provides a component searcher, that crawls through your template files and writes them to a grunt config variable to be used later on. There is a grunt-task that can generate you a static map of your components.
With this basic utilitys you will be able to use SystemJS builder to pack your components in a single static file where the components are protected from uglify and rollup. (yeah, the have the tendency to kick seemingly unused code over board)

Compatiblity

htmlcomponent does nothing else so you can use any library you want.

FAQ

But why not jQuery selecting in the DOM jungle?

Because WebComponents are the way to go. https://www.webcomponents.org/

But this library does only bind a specific DOM Element to a javascript function and pass options...
