grunt-build-html

Build HTML templates recursively.

Getting Started

This plugin requires Grunt ~0.4.1

If you haven't used Grunt before, be sure to check out the Getting Started guide, as it explains how to create a Gruntfile as well as install and use Grunt plugins. Once you're familiar with that process, you may install this plugin with this command:

npm install grunt-build-html --save-dev

Once the plugin has been installed, it may be enabled inside your Gruntfile with this line of JavaScript:

grunt.loadNpmTasks('grunt-build-html');

The "buildHtml" task

Overview

In your project's Gruntfile, add a section named buildHtml to the data object passed into grunt.initConfig().

grunt.initConfig({
  buildHtml: {
    options: {
      // Task-specific options go here.
    },
    your_target: {
      // Target-specific file lists and/or options go here.
    },
  },
})

Options

option.data

Type: String|Object Default: {}

An object containing data that will be available in all templates (files and partials). You may also pass a JSON filepath as a string.

options: {
  data: 'data.json'
}

options.templates

Type: String|Array Default: []

Lets you specify which files you want to be available as partials you can include in files or in other partials (avoid infinite loops). Globbing supported.

options: {
   templates: 'dev/fragments/**/*.html'
}

templateSettings

Type: Object Default: null

The settings passed to underscore when compiling templates.

options: {
  templateSettings: {
    interpolate : /\{\{(.+?)\}\}/g
  }
}

options.templateNamespaceRoot

Type: String Default: null

If empty, templates will simply be loaded with their filename as template key (without extension and regardless of the templates folder structure). If you set the templates root folder, it will serve as the key origin :

• template : test/fragments/subfolder/my-content.html

• templateNamespaceRoot : test/fragments

• template key : subfolder/my-content

options.remoteCacheFolder

Type: String Default: .tmp/remote-cache

If null or empty, an error is thrown.

options: {
  remoteCacheFolder: '<%= config.tmp %>/.cache'
}

options.remoteUrl

Type: Object Default: empty

If empty, each URL will be called without transformation. If you set prefix and/or suffix, they will be appended to all URL.

options: {
  remoteUrl: {     
    prefix: 'http://www.domain.com',
    suffix: '.html'
  }
}

Usage Examples

grunt.initConfig({
  buildHtml: {
    dev: {
      options: {
        templates: 'dev/fragments/**/*.html'
      },
      expand: true,
      cwd: 'dev/',
      src: ['*.html'],
      dest: 'staging/',
      ext: '.html'
    }
  }
})

Basic example

In all templates (files and partials) you can use the include special method to include a partials :

<%= include('my-content') %>

Example with parameters

You can also set extra parameters that will be available in the included template.

dev/my-page.html :

<%= include('head', {title: 'My page'}) %>

dev/fragments/head.html :

<meta charset="utf-8"/>
<title><%- title %></title>

Recursive example

In this example we will define a list of templates that will be processed using a list template that will simply iterate over the parameter to include and concatenate all templates.

dev/my-page.html :

<%= include('list', {params: ['header', 'my-page-content', 'footer']}) %>

dev/fragments/list.html :

<%= _.map(params, function(key){return include(key);}).join('\n')  %>

Ignore sub fragment processing

By default, included fragment will be recursively processed. If you want to prevent the plugin to parse and evaluate your fragment, just add 'true' to the include function :

<%= include('my-fragment', true) %>
<%= include('my-fragment', {params: ['header', 'my-page-content', 'footer']}, true) %>

This is quite handy when dealing with fragment containing code that should not be processed at build time but only run time.

Troubleshooting

You can launch your task with the --debug option to get more debug informations.

In lieu of a formal styleguide, take care to maintain the existing coding style. Add unit tests for any new or changed functionality. Lint and test your code using Grunt.
