Dust Build Status

Demo & Guide

Extensive docs and a full demo are available at


Use Dust if you want these things:

  • async/streaming operation
  • browser/node compatibility
  • extended Mustache/ctemplate syntax
  • clean, low-level API
  • high performance
  • composable templates

This is the LinkedIn fork of dust.js

Details in the blog post :

We will gradually be extending this library with helper functions and bug fixes.

Current LinkedIn additions include:

  • Fix to peg.js to print the line and column number for syntax errors in dust templates
  • Fix to support > node0.4
  • Addition of jasmine test suite, BDD with dust.js
  • There are cases of rendering logic that are best done in templates. @if helper that relies entirely on the js eval for expression evaluation, The perf results are here: We intend to replace the slow js eval with a expression parser soon
  • Section index for lists of maps stored in the dust context for ease of writing simple logic in templates
  • Section size for lists of maps stored in the dust context for ease of writing simple logic in templates
  • Automated Travis CI integration, jasmine for BDD, code coverage report
  • Extend grammar to relax whitespace/eol
  • Add support for rhino in the dust core
  • improve compile times by 10X with changes to how we use peg parser
  • Extend filters for JSON.stringify and JSON.parse
  • logic helpers for select/ switch
  • Support numbers in dust inline params
  • Extend partials to support inline params
  • Support for array references, hence list elements can be accessed via the [] notation
  • Support dynamic blocks, similar to dynamic partials
  • Add pipe support for node
  • Documentation/wiki on the best practices for using dustjs


For Linkedin Dustjs

$ npm install dustjs-linkedin

To render compiled templates in the browser:

<script src="dust-core-1.0.0.min.js"></script>

To compile a template on the command line, use the dustc command. Its syntax is:

dustc [{-n|--name}=<template_name>] {inputfilename|-} [<outputfilename>]

For example, to compile a template on the command line and have it registered under the same name as the source file:

$ dustc template.html

You can customize the name under which the template is registered:

$ dustc --name=mytemplate template.html

Running Tests

To run tests:

$ make test

To generate code coverage report:

$ npm install cover -g
$ make coverage

To view HTML test coverage report:

$ open cover_html/index.html
