grunt-text-include

The best grunt plugin ever.

Include simple text resources such as HTML snippets as strings in your project. I use Handlebars and grunt-contrib-handlebars for my templates, but for parameterless templates you can use this. Read a folder of HTML files and this plugin will output a .js file which contains an object with filenames as keys and contents as values.

Getting Started

If you haven't used grunt before, be sure to check out the Getting Started guide.

From the same directory as your project's Gruntfile and package.json, install this plugin with the following command:

npm install grunt-text-include --save-dev

Once that's done, add this line to your project's Gruntfile:

grunt.loadNpmTasks('grunt-text-include');

If the plugin has been installed correctly, running grunt --help at the command line should list the newly-installed plugin's task or tasks. In addition, the plugin should be listed in package.json as a devDependency, which ensures that it will be installed whenever the npm install command is run.

You may also want to use grunt watch:

watch: {
            options: {
                atBegin: true
            },
            text_include: {
                files: ['app/templates/*.html'],
                tasks: ['text_include']
            },
            handlebars: {
                files: ['app/templates/*.hbs'],
                tasks: ['handlebars']
            }
        }

The "text_include" task

Overview

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

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

Options

options.namespace

Type: String Default value: Templates

Name of the global object which contains the strings. Assigned as this["Templates"] = {...}

options.processName

Type: Function {String -> String} Default value: identity

A function which takes the filename and returns the key this file should have.

options.processContent

Type: Function {String -> String} Default value: identity

A function which takes the file content and returns it.

options.header

Type: String Default value: ``

Text to include before the object.

options.footer

Type: String Default value: ``

Text to include after the object.

Usage Examples

Default Options

In this example, the default options are used to import two text files. So if the testing.html file has the content Testing and the 123 file had the content 1 2 3, the generated result would be the object Templates:

{
    'src/testing.html': 'Testing',
    'src/123': '1 2 3'
}
grunt.initConfig({
  text_include: {
    options: {},
    files: {
      'dest/default_templates.js': ['src/testing', 'src/123'],
    },
  },
})

Custom Options

In this example, custom options are used to make the keys friendlier and append something to the content. So if the app/templates folder contains two html files: testing.html file has the content Testing and the hello-there.html file had the content Hello\n\nthere, the generated result in this case would be the following $T object:

{
    testing: 'Testing - app/templates/testing.html',
    helloThere: 'Hello\n\nthere - app/templates/hello-there.html'
}
grunt.initConfig({
  text_include: {
    options: {
      namespace: '$T',
      processContent: function(fileContent, filePath) {
        return fileContent + ' - ' + filePath
      },
      processName: function (filePath) {
           return filePath.replace(/^app\/templates\//, '').replace(/\.html$/, '').replace(/-(\w)/g, function (match, letter) {
               return letter.toUpperCase();
           });
       }
    },
    files: {
      'dest/templates.js': ['app/templates/*.html'],
    },
  },
})

See the tests for further examples

Header And Footer Options

In this example we will wrap the object with an AMD define. For example, wrap the following object.

{
    'src/testing.html': 'Testing',
    'src/123': '1 2 3'
}

resulting roughly in the equivalent JS file

define([], function () {
    this.Templates = {
        'src/testing.html': 'Testing',
        'src/123': '1 2 3'
    };

    return this.Templates;
});

using the following config settings

grunt.initConfig({
  text_include: {
    options: {
        header: "define([], function () {\n",
        footer: "\nreturn this.Templates;\n});"
    },
    files: {
      'dest/templates.js': ['app/templates/*.html'],
    },
  },
})
