Node.js basic usage

// ======================== app.js ========================

    var  util    = require('util'),
         http    = require('http'),
         nsmarty = require('nsmarty');

	// IMPORTANT! Templates path	
    nsmarty.tpl_path = __dirname + '';
	
	var $arr = {
		// simple {$title}
		title: 'Hi, I am nsmarty template engine!',

		// loop {foreach} ... {/foreach}
		books: [
			{

				price  : '29.54'
			}
		]
	}

	http.createServer(function (req, res) {

	// assign - parse the template.
	var	stream = nsmarty.assign('test.tpl', $arr);
		util.pump(stream, res); // instead of _display() from PHP Smarty.

	}).listen(8000);
	console.log("Server started: http://127.0.0.1:8000/");



// ======================== test.tpl ========================
// create a file called "test.tpl"

	{* NSMARTY TEMPLATE TEST *}

	<h1>{$title}</h1>

	{foreach $books as $i => $book}
		<div style="background-color: {cycle values='cyan,yellow'};">
			[{$i+1}] {$book.title|upper} by {$book.author}

			{if $book.price}                                
				Price: <span style="color:red">€{$book.price}</span>
			{/if}
		</div>
	{else}
		No books
	{/foreach}
	
	{include file="include.tpl"}



// ======================== footer.tpl ========================
// create a file called "footer.tpl"
	I am footer.tpl , the file included from test.tpl



// ======================== Node.js TESTING  ========================
// type in your console

Iterate over arrays and objects

// FOREACH
{$colors = [red=>'#f00', green=>'#0f0', blue=>'#00f']}

{foreach $colors as $name => $code}
    <div style='color:{$code}'>{$code@index}: {$name}</div>
{else}
   no colors
{/foreach}


// SECTION
{$colorNames = [red,green,blue]}

   <div style='color:{$colorCodes[color]}'>{$smarty.section.color.index}: {$colorNames[color]}</div>
{sectionelse}
   no colors
{/section}


// FOR
{for $i=0 to $colorNames|count-1}
   <div style='color:{$colorCodes[$i]}'>{$i}: {$colorNames[$i]}</div>
{/for}


// WHILE
{$j = $colorNames|count}
{while --$j>=0}
