Setup and Install Ionic 3 and Angular 4 Frameworks

The Ionic Framework is use for building high-quality mobile apps using the CLI and Cordova. I hope you love.

What is the Ionic CLI?
The CLI, or command line interface, is a tool that provides a number of helpful commands to Ionic + Angular developers.

-        Run your App

Step 1 - Installing Ionic Framework
The Ionic apps are created and developed by using the Ionic command line utility (the “CLI”) and use Cordova to build and deploy the native app.

Before start the developed of Ionic apps, we need to install some utilities. Ionic is built on top of Cordova, a framework that enables development for cross platforms apps with HTML, CSS and JavaScript.

MPM - npm is the package manager for node.js. It allows us to install, share, and package node modules.

Ionic CLI and Cordova - Before create the Ionic projects, we will need to install the latest version of the CLI, Cordova and latest version of Node.js.

After finished latest version of Node.js Installer, we install the Ionic CLI and Cordova for native app development using the commands to install the utilities globally.

For Windows –
-        npm install -g ionic cordova

For Mac - use “sudo” depending on your system configuration
-        sudo npm install -g cordova ionic

Step 2 - Start an App

Once installed the globally utilities, create your first Ionic app using the commands.
-        ionic start myApp sidemenu


That is the syntax for a new project in Ionic.
o   myApp - will be the directory name and the app name from your project.
o   sidemenu - ionic start myApp sidemenu. This is starter template for your project.
The myApp is any name of your choice and sidemenu is one of the Ionic supported template. The appname and template name is decided by you as per your requirements.

Ionic 3 Framework, default supported template -
1.     blank - ionic start myApp blank
2.     tabs - ionic start myApp tabs
3.     sidemenu - ionic start myApp sidemenu
4.     super - starter project with over 14 ready to use page designs
5.     tutorial - a guided starter project

Step 3 - Run your App
For viewing the app in a browser, we need to run below command
-        cd myApp
-        ionic serve

Starting Angular 4 Apps using Ionic 3 CLI Commands

For starting a new app using Ionic! Use your command line and run below command-
-        ionic start myApp tutorial

start - will tell the CLI create a new app.
myApp - will be the directory name and the app name from your project.
tutorial - will be the starter template for your project.

For new guys, Ionic has a few default templates -
1.     tabs - a simple 3 tab layout
2.     sidemenu - a layout with a toggle menu on the side
3.     blank - a bare starter with a single page
4.     super - starter project with over 14 ready to use page designs
5.     tutorial - a guided starter project

o   ionic serve
Result looks like -
