grunt-json-wrapper

Wraps JSON files in custom wrappers generating a JS file for them. For every wrapper the following placeholders are accepted: {filePath}, {fileName}, {fileExtension}, {filePrefix} and {content}.

Getting Started

This plugin requires Grunt.

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-json-wrapper --save-dev

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

grunt.loadNpmTasks('grunt-json-wrapper');

The "json_wrapper" task

Overview

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

grunt.initConfig({
    json_wrapper: {
        options: {
            // Task-specific options go here
        },
        files: {
            // Files list
        }
    }
});

Options

options.wrapper

Type: String Default value: '(function() { var json = {content}; })();'

A string to be used as a wrapper. This string can and should contain placeholders to wrap and identify specifics about the JSON file.

options.wrapperFile

Type: String Default value: null

A string with a file path containing the wrapping template. The content of this file replaces the value from options.wrapper. Keep it empty if you prefer inline wrapper.

options.extendWith

Type: String Default value: null

A string with a file path containing the a JSON object. The properties from this JSON are used to fill up the files JSON objects missing properties.

options.sort

Type: Boolean Default value: true

Whether to sort the JSON properties.

options.raw

Type: Boolean Default value: false

Whether the JSON file should be wrapped as it is.

options.minify

Type: Boolean Default value: false

Whether the JSON file should be minified by loosing spaces, tabs and new lines.

Wrapping Template Placeholders

{filePath}, {fileName}, {fileExtension}, {filePrefix} and {content}.

Wrapping Template Example

(function (App) {
    'use strict';
 
    App.CultureModel.create({ culture: '{filePrefix}', strings: {content}});
 
})(App);

Usage Examples

Default Options

The default options can be used as the example below. In this case, the 2 language files will have their content wrapped separately but they will be together in the result file.

grunt.initConfig({
    json_wrapper: {
        options: {},
        files: {
            'tmp/default_options.js': ['test/fixtures/pt-BR.json', 'test/fixtures/en-US.json']
        }
    }
});

Custom Options

In this example, custom options are used to do something else with whatever else. So if the testing file has the content Testing and the 123 file had the content 1 2 3, the generated result in this case would be Testing: 1 2 3 !!!

grunt.initConfig({
    json_wrapper: {
        options: {
            wrapper: null,
            wrapperFile: 'test/wrappers/emberApp.txt',
            sort: true, // Default value
            raw: false, // Default value
            minify: false // Default value
        },
        files: {
            'tmp/custom_options.js': ['test/fixtures/pt-BR.json', 'test/fixtures/en-US.json']
        }
    }
});
