Cordova, Grunt and Coffee

You may reference to below if you deside to work with coffee instead of Javascript in Cordova project.

Prepare Cordova Helloworld Project

This guide is based on Hello World project which is generated by the following commands.

$ cordova create hello com.example.hello HelloWorld$ cd hello$ cordova platform add android

InstallInstall coffee Command

$ npm install -g coffee

Install grunt-contrib-coffee Grunt Plugin

$ npm install grunt-contrib-coffee --save-dev

Generate Working Tree

Transform www/js/index.js to src/www/js/index.coffee in example project. Because, we are gotta remote all the javascript file in folderwww/js/.

File src/www/js/index.coffee:

app =     initialize: () -> this.bindEvents()    bindEvents: () ->        document.addEventListener ‘deviceready‘, this.onDeviceReady, false    onDeviceReady: () ->        app.receivedEvent ‘deviceready‘    receivedEvent: (id) ->        parentElement = document.getElementById id        listeningElement = parentElement.querySelector ‘.listening‘        receivedElement = parentElement.querySelector ‘.received‘        listeningElement.setAttribute ‘style‘, ‘display:none;‘        receivedElement.setAttribute ‘style‘, ‘display:block;‘        console.log ‘Received Event: ‘ + id

Update Gruntfile.coffee

module.exports = (grunt) ->    grunt.initConfig        pkg: grunt.file.readJSON ‘package.json‘        coffee:            options:                bare: true            build:                expand: true                cwd: ‘src/www‘                src: [‘**/*.coffee‘]                dest: ‘www‘                ext: ‘.js‘                extDot: ‘first‘    grunt.loadNpmTasks ‘grunt-contrib-coffee‘

Now We Have

• src/ folder as coffee scripts location
• src/www/js/index.coffee file that tranformed from www/js/index.js which is removed already.
• Gruntfile.coffee build with coffee tasks
• package.json which is updated with module grunt-contrib-coffee

Testing

$ grunt coffee$ cordova install android
