In this Tutorial We are going to see the How we can start the Development with FireFox OS and then we Build a Sample Application.
Firfox O.S. completely focus on the Web Applications,so you need not to learn anything new if you are a Web geek .
PreRequsite :
Firfox O.S. completely focus on the Web Applications,so you need not to learn anything new if you are a Web geek .if you are familar with the following term you can jump start .otherwise you can just follow the steps and when you feel free try to learn something about these terms.
Lets Start by setting upp the environment for our Tutorial.
- if you are familer with Git and git hub you can skip these step , otherwise go to the Git and Github download Git and create a free account at Github . After this just follow the instruction for Setup - Git
- There are few Templates already available for developemnt so we are going to start with a basic template. you can get it from Mozila-app-stub or you can clone it directly to your system using the following command (in command myweatherapp is the app name you can give it any name).
$ git clone git@github.com:mozilla/mortar-app-stub.git myweatherapp - Download and Install Node.js. After the installation just open command prompt(windows)or shell(gitor any other terminal) and type following command
.This will install volo utility, which is required to complete this Tutorial.
npm install -g volo - Download Bootstrap . we can do this by using volo add command . the command is shown below .it download the bootstrap from git and add it to your project make sure you run this command from project directory as shown in image . for dependency and global name just hit enter.
volo add bootstrap
- Download and add Underscore.js its the Javascript libarary. you can do it using volo command just like we did in above step
volo add underscore - download modernizr.js and copy it into js/lib folder
- Download Bootstrap zip extract it and copy css/bootstrap.css into to our www/css directory
- Download and Install the Firefox simulator
Lets Begin to Code
you can find the source files under myweatherapp/www directory.Edit Index.html
open the Index.html in any text Editor and copy paste the following script<html> <head> <meta charset="utf-8"> <title>My Weather App</title> <meta name="description" content=""> <!-- Mobile viewport optimized: h5bp.com/viewport --> <meta name="viewport" content="width=device-width"> <!-- Place favicon.ico and apple-touch-icon.png in the root directory: mathiasbynens.be/notes/touch-icons --> <!-- Do not add any other CSS here, instead @import it in app.css. It will be inlined when building. That way it will automatically be minified. --> <link rel="stylesheet" href="css/app.css"> <!-- All JavaScript at the bottom, except this Modernizr build. Modernizr enables HTML5 elements & feature detects for optimal performance. Create your own custom Modernizr build: www.modernizr.com/download/ --> <script src="js/lib/modernizr-2.5.3.min.js"></script> </head> <body> <div class="content"> <ul class="nav nav-tabs"> <li class="active"><a href="#forecast">Forecast</a></li> <li><a href="#settings">Settings</a></li> </ul> <div class="tab-content"> <div class="tab-pane active" id="forecast"> <h1>What's the Forecast?</h1> <h2 class="name"></h2> <section class="day1"> <h3>Today:</h3> <p class="low">Low: <span></span></p> <p class="high">High: <span></span></p> </section> <section class="day2"> <h3>Tomorrow:</h3> <p class="low">Low: <span></span></p> <p class="high">High: <span></span></p> </section> </div> <div class="tab-pane" id="settings"> City, zip code, or place: <input type="text" name="place" /> <div> <button class="btn save">Save</button> </div> </div> </div> </div> <!-- JavaScript at the bottom for fast page loading: http://developer.yahoo.com/performance/rules.html#js_bottom --> <!-- Using require.js, a module system for javascript, include the js files. This loads "main.js", which in turn can load other files, all handled by require.js: http://requirejs.org/docs/api.html#jsfiles --> <script type="text/javascript" data-main="js/app.js" src="js/lib/require.js"></script> </body> </html>Edit js/app.js
To add any javascript libarary to our code we Define the require.js using the folloing statementand put our code insde it. to use any javascript libaray we use the require function function. if you remeber we downloded the underscore.js in setup steps now we add the library by following commanddefine(function(require) { }Now we open the app.js and replace the code with the following code.var _ = require('underscore');
//simillary we add the bootsrap-tab libaray
require('bootstrap/js/bootstrap-tab');require.config({ baseUrl: 'js/lib', paths: {'jquery': ['//ajax.googleapis.com/ajax/libs/jquery/1.7.2/jquery.min', 'jquery']}, }); // When you write javascript in separate files, list them as // dependencies along with jquery define("app", function(require) { var $ = require('jquery'); var _ = require('underscore'); require('bootstrap/js/bootstrap-tab'); function fetchForecast(woeid) { var query = escape('select item from weather.forecast where woeid="' + woeid + '"'); var url = ("http://query.yahooapis.com/v1/public/yql?q=" + query + "&format=json&callback=?"); $.getJSON(url, function(data) { var item = data.query.results.channel.item; var forecast = item.forecast; $('h2.name').text(item.title); for(var i=0; i<forecast.length; i++) { var el = $('.day' + (i+1)); el.find('.high span').text(forecast[i].high); el.find('.low span').text(forecast[i].low); } $('.nav-tabs a:first').tab('show'); }); } fetchForecast(localStorage.placeWoeid || '2480894'); $('.nav-tabs a').click(function(e) { $(this).tab('show'); }); $('#settings button.save').click(function(e) { var place = $('#settings input[name=place]').val(); var query = "places.q('" + escape(place) + "')"; var url = ('http://where.yahooapis.com/v1/' + query + "?appid=Zz.TvXLV34Go6RzyHMnH6scOSn_DdLYdyuJVbd6l2MLvuTAAEFIylCIj7Koo_pth7BHeGmNV5m0zdAkAY_CspQ9eKlJRlmM-&format=json&callback=?"); $.getJSON(url, function(data) { if(data.count !== 0) { var p = data.places.place[0]; localStorage.placeWoeid = p.woeid; fetchForecast(p.woeid); } }); }); });- Now we add some CSS to our code .so open css/app.css folder and replace the code with following
/* Tip: Use "@import" to add styles instead of adding 's in your HTML, and volo will inline it when building for production */ /* Styles for the installation button */ @import "install-button.css"; /* Your styles here */ @import "bootstrap.css"; /* @import "bootstrap-responsive.css"; */ body { background-color: #d3dde5; } .day1 { margin-top: 1em; } #forecast p { margin: 1em; } .nav-tabs { margin: 0; } .content { padding-top: 1em; background: #ffffff; /* Old browsers */ background: -moz-linear-gradient(top, #ffffff 0%, #d3dde5 100%); /* FF3.6+ */ background: -webkit-gradient(linear, left top, left bottom, color-stop(0%,#ffffff), color-stop(100%,#d3dde5)); /* Chrome,Safari4+ */ background: -webkit-linear-gradient(top, #ffffff 0%,#d3dde5 100%); /* Chrome10+,Safari5.1+ */ background: -o-linear-gradient(top, #ffffff 0%,#d3dde5 100%); /* Opera 11.10+ */ background: -ms-linear-gradient(top, #ffffff 0%,#d3dde5 100%); /* IE10+ */ background: linear-gradient(to bottom, #ffffff 0%,#d3dde5 100%); /* W3C */ filter: progid:DXImageTransform.Microsoft.gradient( startColorstr='#ffffff', endColorstr='#d3dde5',GradientType=0 ); /* IE6-9 */ } .content h1 { margin: .25em 0; } section p, #settings { font-size: 1.25em; } .tab-content { padding: 1em; }
Debug, Build and Deploy
Debug:
to dubeg our app we launch server through volo command . as shown belowvolo serve
http://localhost:8008/
Time to Build The App
To build the Application use the volo command as show belowvolo build$ volo serve base=www-built
Lets Deploy :)
Now we are done with built and we tested it so now we can deploy our app to Github its free so if you don't have account get one for you and follow the command given belowvolo ghdeploy
