Now let's begin with our introduction to Ionic 4 and hybrid apps.
What is Hybrid Mobile Development?
Hybrid mobile development refers to the process of developing mobile apps using a mix of web technologies, which were designed on the first place to build web apps, thanks to some clever developers who built tools used to adopt the existing web tools in order to build native-like mobile apps.
Ionic 4 (and its previous versions) is based on Apache Cordova (future versions will use Capacitor by default but will also support Cordova) so what is Cordova and what it does?
Apache Cordova is by itself a framework to build hybrid mobile apps but also a native web container or more precisely an embedded browser based on Chromium which allows you to package and present users with a web application which has a mobile like user interface, that can be downloaded from app stores, installed on the user device and more importantly have access to native device features such as Geolocation, different sensors and Camera etc.
Before answering this question, let's answer an important related question:
What is Ionic?
Ionic is a hybrid mobile framework used to build cross-platform mobile apps that can target Android, iOS and Windows with the same code base. It allows developers to build once and deploy everywhere.
Ionic is based on Cordova which means all interfacing with underlying device system features is done with Cordova. In fact the pure Ionic library is just a mobile User Interface library that offers developers common UI controls and patterns which have two main goals:
You can build your mobile application without being a mobile UI designer or a CSS guru.
You can build your mobile application without worrying about best practices and performance issues.
Ionic has two major versions which are both based on Cordova for low level features but uses different stack on top level.
Ionic 2/3 is the second major version which is based on Angular 2/4/5, a completely rewritten from scratch framework based mainly on TypeScript, with better performance and more features than AngularJS.
So now that you have a basic understanding of Ionic and hybrid mobile development. Let's learn about the first steps to get started.
Before you can build mobile apps with Ionic, you need to have a development environment with Node.js and NPM installed.
You can install Node.js with NPM following easy steps in major operating systems.
The simplest solution is to go to the official Node.js website and download the installer compatible with your operating system.
If you use Ubuntu, you can also follow How To Install Node.js on Ubuntu 16.04.
Once you have installed the requirments. You need to install the Ionic CLI--a Node utility that allows you to generate Ionic projects from the command line interface.
Installing the Ionic Command Line Interface (CLI) is easy. Simply run the following command:
$ npm install -g ionic@latest
You can then verify the installation by running:
$ ionic --version
You should get the installed version of Ionic.
You can find more information about the CLI from this page on the official docs.
How to Use Cordova
In Ionic 4, the only way you have to bring native capabilities to Ionic apps is through Cordova (for Ionic 4+, you'll have Capacitor as the default option and Cordova too). You can install Cordova using:
$ npm install -g cordova
You can use any Cordova command through the
ionic cordova command.
You can find the Cordova CLI commands from this link.
Creating your First Ionic 4 Project
After installing the required dependencies. You can now use the Ionic CLI to generate Ionic projects based on various starters: For example for to generate a blank project, simply run the following command:
ionic start myapp blank --type=angular
For detailed instructions about generating Ionic 4 project using the Ionic CLI you need check this tutorial.
