In this post, you will learn how to start any application using Ionic Framework. We will start with the downloading process of ionic and all the dependencies that are needed for developing any application.

Also we need to know the platforms that are supported with the current release of ionic: iOS 7+,  Android 4.1+

Before installing ionic, you need to install the latest version of Apache Cordova. To install cordova, you should have node.js, then run the following command:

$ sudo npm install -g cordova

To install ionic run the following command:

$ sudo npm install -g ionic

After installing ionic, you can create a project in a directory:

$ ionic start newproject blank

This will create a new project named newproject. Here is the structure of the project created after running this command:

$ cd todo && ls

 bower.json     // bower dependencies
 config.xml     // cordova configuration
 gulpfile.js    // gulp tasks
 hooks          // custom cordova hooks to execute on specific commands
 ionic.project  // ionic configuration
 package.json   // node dependencies
 platforms      // iOS/Android specific builds will reside here
 plugins        // where your cordova/ionic plugins will be installed
 scss           // scss code, which will output to www/css/
 www            // application - JS code and libs, CSS, images, etc.

Adding Platforms:
you need to add the platforms which you want to add into your project:

$ ionic platform add ios
$ ionic platform add android

After adding the platforms you can check and start your application by running the following command:

$ ionic build ios
$ ionic emulate ios
