    Build Status

    An expressjs plugin for handling DustJS view rendering. dustjs-helpers are included by default in this module.

    var express = require('express');
    var app = express();
    var adaro = require('adaro');
    var options = {
      helpers: [
        //NOTE: function has to take dust as an argument.
        //The following function defines @myHelper helper
        function (dust) { dust.helpers.myHelper = function (a, b, c, d) {} },
        '../my-custom-helpers',   //Relative path to your custom helpers works
        'dustjs-helpers',   //So do installed modules
          name: '../my-custom-helpers/helper-to-render-data-with-args',
          // or use this signature if you need to pass in additional args
          arguments: { "debug": true }
    app.engine('dust', adaro.dust(options));
    app.set('view engine', 'dust');
    // For rendering precompiled templates:
    // app.engine('js', adaro.js({ ... ));
    // app.set('view engine', 'js');

    Make sure that if you've app.set('views', somepath) that the path separators are correct for your operating system.


    Config options can be used to specify dust helpers, enabled/disable caching, and custom file loading handlers.

    helpers (optional) String Array, helper module names

    A helper module must either:

    • Conform to the API established by dustjs-helpers provided by LinkedIn or
    • Export a function which accepts a single argument (being dust itself). Such files should generally be designed for use on both client and server.

    Client and Server Compatible

    function setupHelpers(dust) {
       // Add helpers
    if (typeof exports !== 'undefined') {
        module.exports = setupHelpers;
    } else {

    Alternate API

    module.exports = function (dust) {
        // Add helpers

    cache (optional, defaults to true) Boolean

    Set to true to enable dust template caching, or false to disable.

    app.engine('dust', dustjs.dust({ cache: false }));
    app.set('view engine', 'dust');

    helpers (optional) An array of helper modules to require and use.

    Expects helpers to be in the form of:

    module.exports = function (dust, [options]) {
        dust.helpers.something = function (chunk, context, bodies, params) {

    Breaking changes


    • Removed the layout: option to render and in configuration
    • Dust is our own private instance, not global. If you load helpers, you must do it in the configuration of adaro.
    • We outright require dust. We will not use your application's installed version.
    • Dust ~2.7.1 is required. Dust minors are breaking changes, so those affect users of this module too.
    • Paths passed to the engine that are filesystem absolute paths will be used as is, and not resolved against the view root.
    • dustjs-helpers is not loaded for you automatically. Add it to your helpers configuration if you want it. Make sure you use a version compatible with the dustjs-linkedin that adaro uses.
