grunt-handlebars-static

Created at iCrossing 12.1.2012 by Arne Strout Generate static HTML from handlebars templates as a part of the build process with this highly configurable plugin for Grunt.

Getting Started

Install this grunt plugin next to your project's grunt.js gruntfile with: npm install grunt-handlebars-static

Then add this line to your project's grunt.js gruntfile:

grunt.loadNpmTasks('grunt-handlebars-static');

Important note

This package makes some assumptions about the way you are using handlebars templates, it is intended only for backend use, and is not intended for situations in which the same template files are being shared between the front end and the back-end. I may include support for that in the future however, we shall see. Also this plugin is built around Grunt ~0.3.18 and will require updating before it will be compatible with 0.4a when it becomes stable.

Project configuration

The below example configuration is the scenario that has so far been developed for. It assumes there is a folder structure under 'app/' which contains many .HBT (partials) and .HBR (templates). The .HBR files will be compiled into HTML files in the same folder structure but under the 'dist/' folder. By default a folder named 'hbr-context' containing a .json file with the same name as the .HBR file will be used as the context. A custom handlebars directive has been added to include your context inline, or to specify it in the .HBR file.

Note: The .HBR and .HBT extensions are my personal preference, you can use whatever extensions you like by just changing the wildcards.

// Project configuration
grunt.initConfig({
    // configuration options
    'handlebars-static':{
        dev:{
            partials:'app/**/*.hbt', // Wildcard for partials to compile
            files:'app/**/*.hbt', // Wildcard for templates to compile into HTML
            data:'hbr-context/*.json', // Wildcard for default context JSON, will be ignored if inlined
            replaceDir:'app/', // The directory you are reading templates from
            withDir:'dist/' // The directory you are publishing to
        }
    }
});

Usage examples

Once you have installed the NPM module, there will be an "examples" folder under the root. This folder contains a complete example project, including a helpful watch task, which demonstrates the use of the task.

Inline context

You can specify the context for your .HBR template by using a custom comment directive which the module will read as a JSON object. It will also execute inline directives within that JSON object to allow you to specify external .json files to use as portions of the context for the given template. This allows for much greater sharing of data between templates, such as the way that the aforementioned example project includes the topnav data.

{{! *** Handlebars Context Inline Configuration **** }}
{{! 
    context:{
        "page":"<context:hbr-json/index.json>",
        "topnav":"<context:common/hbr-json/topnav.json>"
    }
!}}

The important part is this directive:

{{! context: {JSON DATA GOES HERE} }}

However also note the use of the context directive:

context:{
    property:<context:path/to/my.file>
}

This will load that file inline and process it as a JSON file, then assign that object to the property.

Referencing partials

Your partials will be given the name of the partial file, prefixed by the path delimited by _ rather than /, in a future build I plan to add a preprocessor so that you can use / instead since it is much more natural, using it without a preprocessor will crash handlebars.

{{> common_topnav}}

This references the file app/common/topnav.hbt if using the configuration outlined above. You can specify a context for the partial per usual Handlebars syntax:

{{> path_to_my_partial context}}
