Render templates from text, files and URLs with TEMPLATE

TEMPLATE(source, model, [$]) renders a Tangular template and returns a promise with the text. The source can be:

a text that contains {{ ... }}: it is the template itself
the name of a file of the templates folder: TEMPLATE('invoice', model) reads templates/invoice.html (a ~ at the start makes the name an absolute path)
an http:// or https:// address, which the source of total5 downloads (not checked on this page)

Ta is another name of Tangular. Unlike Tangular.render(), the model is available as value: write {{ value.name }}. A template file can also carry two blocks that TEMPLATE reads and removes from the output: a <script> that adds helpers to Thelpers and a <script type="text/json"> with the default model, which is used when no model is passed.

templates/invoice.html

<script>
	Thelpers.money = function(value) {
		return (value || 0).toFixed(2) + ' EUR';
	};
</script>
<script type="text/json">{ "customer": "Anonymous", "total": 0 }</script>
<h1>Invoice for {{ value.customer }}</h1>
<p>Total: {{ value.total | money() }}</p>
