About

This task renders Dust templates against a context to produce HTML.

Getting Started

Install this plugin with the command:

npm install grunt-dust-html

Next, add this line to your project's grunt file:

grunt.loadNpmTasks("grunt-dust-html");

Lastly, add the configuration settings (see below) to your grunt file.

Documentation

This task has two required properties, src and dest. src is the path to your source file and dest is the file this task will write to (relative to the grunt.js file). If this file already exists it will be overwritten.

An example configuration looks like this:

grunt.initConfig({
  dusthtml: {
    dist: {
      src: "src/home.dust",
      dest: "dist/home.html",

      options: {
        // see below for options. this is optional.
      }
    }
  }
});

Optional Configuration Properties

This plugin can be customized by specifying the following options:

  • whitespace: Whether or not to preserve whitespace. false by default.
  • basePath: The base location to all your templates so that includes/partials can be resolved correctly.
  • defaultExt: The default template extension. Defaults to .dust.
  • module: The name of the Dust module to use. Defaults to dustjs-linkedin but can also be dust for plain ol' dust, or dustjs-helpers for the LinkedIn Dust build with helpers. If this option is anything other than the default, make sure you have installed the module via npm install.
  • context: A JavaScript object to render the template against. This option supports a few different types:

String: the location to a file containing valid JSON:

context: "/path/to/file.json"

Object: a regular ol' JavaScript object:

context: {
  pageTitle: "My Awesome Website"
}

Array: an array of contexts, either string (files to parse) or JavaScript objects, or both. Each item in the array will be merged into a single context and rendered against the template:

context: [
  "path/to/context.json",
  "path/to/another/context.json",
  { more: "data" }
]

FAQ

  1. Why does the output say undefined?
    Most likely dust is trying to include a file but it can't resove the path properly. Make sure you're setting a basePath option.
