Merge Handlebars templates to one file.

Inspiried by grunt-contrib-handlebars and grunt-handlebars-min

Getting Started

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-handlebars-merge --save-dev

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

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

Handlebars task

Run this task with the grunt hbsmerge command.

Task targets, files and options may be specified according to the grunt Configuring tasks guide.

Options

namespace

Type: String or false or function
Default: 'Templates'

The namespace in which templates will be assigned.

Example:

options: {
  namespace: 'Templates'
}

processContent

Type: Function

This option accepts a function which takes two arguments (the template file content, and the filepath) and returns a string which will be used as the source for the precompiled template object. The example below removes leading and trailing spaces to shorten templates.

options: {
  processContent: function(content, filepath) {
    content = content.replace(/^[\x20\t]+/mg, '').replace(/[\x20\t]+$/mg, '');
    content = content.replace(/^[\r\n]+/, '').replace(/[\r\n]*$/, '\n');
    return content;
  }
}

processName

Type: Function

This option accepts a function which takes one argument (the template filepath) and returns a string which will be used as the key for the precompiled template object. The example below stores all templates on the default JST namespace in capital letters.

options: {
  processName: function(filePath) {
    return filePath.toUpperCase();
  }
}

processPartialName

Type: Function

This option accepts a function which takes one argument (the partial filepath) and returns a string which will be used as the key for the precompiled partial object when it is registered in Handlebars.partials. The example below stores all partials using only the actual filename instead of the full path.

options: {
  processPartialName: function(filePath) {  // input: templates/_header.hbs
    var pieces = filePath.split("/");
    return pieces[pieces.length - 1];       // output: _header.hbs
  }
}

Note: If processPartialName is not provided as an option the default assumes that partials will be stored by stripping trailing underscore characters and filename extensions. For example, the path templates/_header.hbs will become header and can be referenced in other templates as {{> header}}.

partialRegex

Type: Regexp
Default: /^_/

This option accepts a regex that defines the prefix character that is used to identify Handlebars partial files.

// assumes partial files would be prefixed with "par_" ie: "par_header.hbs"
options: {
  partialRegex: /^par_/
}

partialsPathRegex

Type: Regexp
Default: /./

This option accepts a regex that defines the path to a directory of Handlebars partials files. The example below shows how to mark every file in a specific directory as a partial.

options: {
  partialRegex: /.*/,
  partialsPathRegex: /\/partials\//
}

partialsPathRegex

Type: Regexp
Default: /./

This option accepts a regex that defines the path to a directory of Handlebars partials files. The example below shows how to mark every file in a specific directory as a partial.

options: {
  partialRegex: /.*/,
  partialsPathRegex: /\/partials\//
}

minify

Type: Bool
Default: false

This option turns on template minification.

options: {
  minify: true
}

clearHtmlComments

Type: Bool
Default: true

Remove HTML comments () from templates.

options: {
  clearHtmlComments: false
}

clearHandlebarsComments

Type: Bool
Default: true

Remove Handlebars comments ({{!-- --}}) from templates.

options: {
  clearHandlebarsComments: false
}

templateQuotes

Type: Number
Default: 2

Convert quotes inside templates:

1 - Convert double quotes to single

2 - Convert single quoters to double

options: {
  templateQuotes: 1
}

Usage Examples

hbsmerge: {
  compile: {
    options: {
      minify: true,
      templateQuotes: 1
    },
    files: {
      "path/to/result.js": "path/to/source.hbs",
      "path/to/another.js": ["path/to/sources/*.hbs", "path/to/more/*.hbs"]
    }
  }
}

hbsmerge: {
  compile: {
    options: {
      minify: true,
      templateQuotes: 1
    },
	src: ["path/to/templates/**/*.hbs"],
	dest: "path/to/templates/mergedTemplates.js",
  }
