`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.

```html 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>
```

```js controllers/documents.js
exports.install = function() {
	ROUTE('GET /text/', text);
	ROUTE('GET /file/', file);
	ROUTE('GET /default/', withdefault);
	ROUTE('GET /absolute/', absolute);
	ROUTE('GET /alias/', alias);
};

async function text($) {
	$.plain(await TEMPLATE('Hello {{ value.name }}!', { name: $.query.name || 'world' }));
}

async function file($) {
	$.plain(await TEMPLATE('invoice', { customer: 'Ana', total: 12.5 }));
}

function alias($) {
	$.json({ same: Ta === Tangular, rendered: Ta.render('{{ name }}', { name: 'x' }) });
}

async function absolute($) {
	const file = require('path').join(__dirname, '..', 'templates', 'invoice.html');
	$.plain(await TEMPLATE('~' + file, { customer: 'Eva', total: 1 }));
}

async function withdefault($) {
	$.plain(await TEMPLATE('invoice'));
}
