Getting Started with Ionic

Chapter 2. Setting up the Environment the Right Way

In this chapter we will learn how to set up our development environment and build a dummy app to verify the correct setup. This chapter also defines the possible and popular issues faced during setup so that you do not face any bottlenecks during the process. The instructions are separated for Windows OS, generic Linux OS, and Mac OS.

As we have discussed, Ionic has evolved into an ecosystem from a basic framework. It is very important that we set up our development tools the right way to leverage the full potential of this ecosystem.

We will be setting up a lot of software just for developing Mobile Apps, but if we want to use the power of developing for multiple platform apps using a single codebase, we have to do this. Any Native App is always built using the Native Development tools and hence we have to install and set up a Native Mobile development environment for all the platforms.

Apart from the build tools of native environments...

Setting up Native Mobile development environments

Native Mobile development environments are specific to your operating system and hence there will be separate instructions for installing on Windows/Mac/Linux. The native environment SDKs are heavy so would require fast Internet speed to download. You need to be on a good network to be able to download it.

For iOS

These days iOS Apps are built for iPhone, iPad and iWatch devices. Objective-C is the primary language used to develop iOS Native Apps. Xcode is Apple's IDE (integrated development environment), which includes a graphical user interface and many other features. iOS SDK is required along with Xcode as it provides additional tools, compilers, and frameworks to build iOS Apps for phones, tablets, and smartwear devices (iWatch).

Note

For developing or building iOS Apps, a Macintosh machine is strictly required so if you do not have a Mac, please skip this section. Mac machines should have OS X 10.9.4 or later.

In order to download...

Ionic development environment

Ionic Framework is based on Apache Cordova, which takes care of build and plugin management. Apache Cordova CLI uses the NodeJS package manager called NPM for dependency management.

Installing NodeJS

NodeJS is a JavaScript-based server-side environment to build backend systems. NodeJS has an efficient package manager that takes care of installing and maintaining a central repository of packages, version management, and dependency management. NPM has become the default dependency manager for a lot of other frameworks apart from NodeJS. Ionic Framework also leveraged this successful package manager so we have to install it for Hybrid App development.

In order to install NodeJS, download the binary for the respective OS—Windows, Linux, or Mac OS from https://nodejs.org/download/.

On a Mac or Linux, you can use a package manager such as brew to install NodeJS:

$ brew install node

After the node installation is complete, please type in the following commands to...

Basic Ionic CLI commands

Ionic commands help you smoothly create a new project and test it easily while you are developing it. The first command you should learn to execute is the ionic info command. This would help you to know all about your system environment that you have set up so far. If there are any errors, you can debug and resolve them before beginning the development.

The command and a sample output is given here:

$ ionic info
Your system information:
OS: Mac OS X Yosemite
Node Version: v0.12.4
Cordova CLI: 5.1.1
Ionic CLI Version: 1.6.2
Xcode version: Xcode 6.4 Build version 6E35b
ios-sim version: 3.1.1
ios-deploy version: 1.7.0

Another quick utility command is to go to the Ionic docs for a specific topic:

$ ionic docs <TOPIC>

Please go through the commands in this section in order to understand the steps required to build a dummy app to test the environment.

The next command to learn is to start a new project. Ionic has multiple flags/options along with this command to set...

Building a dummy app

After successfully setting up the environment correctly, you must be excited to build your first app. In this section of the chapter, we will use the commands to learn how to create a sample Ionic-based Hybrid App and build it to run on an actual device or emulator:

  1. We will create the initial project using the Ionic start command and name our project MyFirstApp. The output will be as illustrated in the following screenshot:
    Building a dummy app
  2. After the successful creation of your project with the default Ionic template, go to your project folder using the command $ cd MyFirstApp.

    Now, as we are in an Ionic project folder, we can run Ionic project-specific CLI commands. Any platform can be added to the project to build the specific app:

    $ ionic platform add android
    

    We will add an Android platform as it will work on all machines, such as Windows, Linux, or Mac. Ionic will download Android-specific default resources such as icons and splash screens, and also add some important plugins by default...

Popular issues faced and solutions

The development environment set up for Ionic Hybrid App development is a lengthy and cumbersome process. It is evident that you may face some issues in installing and setting up all these systems. This section mentions the most common and popular issues faced along with their solutions so that you do not get stuck somewhere:

  • Permission issue [Mac or Linux]: A lot of the time, the user you are logged in as does not have permission to alter files and directories while creating projects. This problem can occur in npm install commands and Ionic start commands.
    • Solution: Use a sudo keyword before any command to run in privileged mode.
  • Unable to find npm global modules: If you have installed a global npm package using -g flag but are unable to use it, you may need to add the npm directory to your path in order to invoke globally installed modules.
    • Solution: Add the npm directory location to your path. On Windows, npm can usually be found at C:\Users\username\AppData...

What is custom duty/charge? Chevron down icon Chevron up icon

Customs duty are charges levied on goods when they cross international borders. It is a tax that is imposed on imported goods. These duties are charged by special authorities and bodies created by local governments and are meant to protect local industries, economies, and businesses.

Do I have to pay customs charges for the print book order? Chevron down icon Chevron up icon

The orders shipped to the countries that are listed under EU27 will not bear custom charges. They are paid by Packt as part of the order.

List of EU27 countries: www.gov.uk/eu-eea:

A custom duty or localized taxes may be applicable on the shipment and would be charged by the recipient country outside of the EU27 which should be paid by the customer and these duties are not included in the shipping charges been charged on the order.

How do I know my custom duty charges? Chevron down icon Chevron up icon

The amount of duty payable varies greatly depending on the imported goods, the country of origin and several other factors like the total invoice amount or dimensions like weight, and other such criteria applicable in your country.

For example:

  • If you live in Mexico, and the declared value of your ordered items is over $ 50, for you to receive a package, you will have to pay additional import tax of 19% which will be $ 9.50 to the courier service.
  • Whereas if you live in Turkey, and the declared value of your ordered items is over € 22, for you to receive a package, you will have to pay additional import tax of 18% which will be € 3.96 to the courier service.
