JST minifed template

produce JST file with minified html

Getting Started

This plugin requires Grunt ~0.4.2

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 jstminifiedtpl --save-dev

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

grunt.loadNpmTasks('grunt-jstminifiedtpl');

The "JST minifed template" task

Overview

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

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

Options

options.removeComments

Type: Boolean Default value: true

Remove comments in HTML

options.collapseWhitespace

Type: Boolean Default value: true

Remove white space in HTML

options.removeEmptyAttributes

Type: Boolean Default value: true

Remove empty attributes from HTML tags

options.prefix

Type: String Default value: window.JST=

The global scope var to be used to set the minified templates in the jst file

options.wrapfunction

Type: String Default value: ``

Wrap the minified template into a function, not wrapped by default

options.wrapfunctionresult

Type: String Default value: ``

Wrap the entire minified template json object into a function, not wrapped by default

options.removekeyprefix

Type: String Default value: ``

Basically the relative path of each file minified into JST will be used as key in the resulting object, here you can define what part of the key to remove. If your files are located at templates/foo/bar/main.html then your key in the resulting object will be templates/foo/bar/main. But lets say you want to get rid of the templates/foo/ so your key results in bar/main, then set the option to templates/foo/

options.appendJSCode

Type: String Default value: ``

You can append some js code after the resulting object. If you have window.JST={"foo":"

Usage Examples

Default Options

In this example, the default options are used to do something with whatever. Resulting file will have window.JST having both HTML file minified. So test.js can be used to load HTML with only one js file (JST).

grunt.initConfig({
  jstminifiedtpl: {
    options: {},
    files: {
      'dest/test.js': ['src/a.html', 'src/b.html'],
    },
  },
});

Custom Options

In this example, custom options are used to do something else. We prefix the result with window.JST as usual, comments are removed, white space and empty attr too. HTML files in src/ and src/a will be minified and put into result object (window.JST)

grunt.initConfig({
  jstminifiedtpl: {
    options: {
      prefix: 'window.JST',
      wrapfunction: '',
      removeComments: true,
      collapseWhitespace: true,
      removeEmptyAttributes: true
    },
    files: {
      'dest/tpl.js': ['src/*.html', 'src/a/*.html'],
    },
  },
});

Here we use wrapfunction and appendJSCode: Each minified template/HTML will be wrapped within function myfunction, so we can do something before they are assigned to window.JST. Then we append some additional code after the window.JST object, for example to do something with the resulting window.JST.

grunt.initConfig({
  jstminifiedtpl: {
    options: {
      prefix: 'window.JST',
      wrapfunction: 'myfunction',
      appendJSCode: 'doSomething(window.JST);',
      removeComments: true,
      collapseWhitespace: true,
      removeEmptyAttributes: true
    },
    files: {
      'dest/tpl.js': ['src/*.html', 'src/a/*.html'],
    },
  },
});

Here we use wrapfunction and appendJSCode: Each minified template/HTML will be wrapped within function myfunction, so we can do something before they are assigned to window.JST. Then we append some additional code after the window.JST object, for example to do something with the resulting window.JST. Additionally we remove src/ from the keys so our resulting object will only contain html filenames as keys.

grunt.initConfig({
  jstminifiedtpl: {
    options: {
      prefix: 'window.JST',
      wrapfunction: 'myfunction',
      appendJSCode: 'doSomething(window.JST);',
      removekeyprefix: 'src/'
      removeComments: true,
      collapseWhitespace: true,
      removeEmptyAttributes: true
    },
    files: {
      'dest/tpl.js': ['src/*.html', 'src/a/*.html'],
    },
  },
});

Here we use wrapfunctionresult and appendJSCode: Each minified template/HTML will be wrapped within function myfunction, so we can do something before they are assigned to window.JST. Then we append some additional code after the window.JST object, for example to do something with the resulting window.JST. Additionally we remove src/ from the keys so our resulting object will only contain html filenames as keys.

grunt.initConfig({
  jstminifiedtpl: {
    options: {
      prefix: '',
      wrapfunctionresult: 'myfunction',
      appendJSCode: 'doSomething();',
      removekeyprefix: 'src/'
      removeComments: true,
      collapseWhitespace: true,
      removeEmptyAttributes: true
    },
    files: {
      'dest/tpl.js': ['src/*.html', 'src/a/*.html'],
    },
  },
});
