jst

Node JavaScript Template

Node-jst is a pretty high performance template engine and implemented with JavaScript for Node.js

Installation

via npm:

npm install jst

Features

• Automatically caching of intermediate JavaScript
• Unbuffered code for embed codes etc {% code %} or {{ variable }}

Example

{% if (user) { %}
  <h2>{{ user.name }}</h2>
{% } %}

Usage

var jst = require('jst');

// Render a string
jst.render('Hello {{ name }}', {name: 'jst'});

// Render a file
jst.renderFile('path/to/some.html', {name: 'jst'}, function(err, ctx) {
  // second arg are optional,
  // the callback can be the second arg
});

// Compile a function
var fn = jst.compile('Hello {{ name }}');
fn({name: 'jst'});

// Use `it.` as prefix of variables so that you can run it more than 30 times faster
jst.render('Hello {{ it.name }}', {name: 'jst'});

// Filters
jst.render('Hello {{ it.name|e }}', {name: '<strong>jst</strong>'});
jst.render('{{ it.entry|e|linebreaks }}', {entry: '...'});
jst.render('{{ it.value|add(123) }}', {value: 123});

// Custom filters
jst.addFilter('filterName', function(src) { ... });
jst.addFilters({anotherFilter: function(src) { ... }});
jst.render('{{ it.value|filterName }}', {value: 123});
jst.render('{{ it.value|anotherFilter }}', {value: 123});
// or
jst.addFilter('filterName', function(arg1, arg2, arg3) { return function(src) { ... }});
jst.render('{{ it.value|filterName(1, 2, 3) }}', {value: 123});

// i18n
jst.render('{{ _("Hello {it.name}")|e }}', {name: '<strong>jst</strong>'});

// Client side
<script src="jst.js"></script>
<script>
  jst.render('Hello {{ it.name }}', {name: 'jst'});
</script>

Benchmarks

A brief comparison of some JavaScript templating engines on a short template: 7 DOM nodes ... 7 interpolated values.
