Ionic 2 Cookbook

Chapter 2. Adding Ionic 2 Components

In this chapter, we will cover the following tasks related to using Ionic 2 components:

  • Adding multiple pages using tabs
  • Adding left and right menu navigation
  • Navigating multiple pages with state parameters

Introduction

It's possible to write a simple app with a handful of pages. Ionic provides a lot of out-of-the-box components that allow simple plug-n-play operations. When the app grows, managing different views and their custom data at a specific time or triggered event could be very complex. Ionic 2 comes with some changes in handling state and navigation. In Ionic 1, you could use UI-Router for advanced routing management mechanism. In Ionic 2, NavController will enable the push/pop implementation of the navigation.

Since Ionic 2 introduces many new components, you have to understand how these components impact your app state hierarchy and when each state is triggered.

Adding multiple pages using tabs

This section will explain how to work with the Ionic tab interface and expand it for other cases. The example used is very basic with three tabs and some sample Ionic components in each tab. This is a very common structure that you will find in many apps. You will learn how Ionic 2 structures the tab interface and how it translates to individual folders and files.

In this example, you will build three tabs, as follows:

  • Showing a simple text-only page to explain where to fit the components
  • Showing a sign up form
  • Showing a horizontal slider box

Although the app is very straightforward, it will teach you a lot of key concepts in Angular 2 and Ionic 2. Some of them are the component decorators, theme and the TypeScript compiler process.

Here is a screenshot of the app where the middle tab is selected:

Adding multiple pages using tabs

Getting ready

Since this is your first app being built from scratch, you need to ensure that you have followed through Chapter 1, Creating Our First App with Ionic 2,...

Adding left and right menu navigation

Menu navigation is a very common component in many mobile apps. You can use menu to allow users to change to different pages in the app, including login and logout. The menu could be placed on the left or right of the app. Ionic 2 also lets you detect events and customize the menu's look and feel further.

This is a screenshot of the app you will develop:

Adding left and right menu navigation

The app will have two pages and two menus. You can toggle either the left or right menu (but not both at the same time). In reality, it is much less likely that you will have both menus, but for the purposes of demonstration, this app will include both menus as the app will show the different properties of the menus that you can set. The left menu will change the page and the right menu will allow you to capture the exact item that is clicked on.

Getting ready

This app can run on your web browser, so there is no need to have a physical device available. Again, you only need to have Ionic 2 available...

Navigating multiple pages with state parameters

App navigation is an important topic because it's the core of a user's experience. You want to manage the user's expectation on what would happen after they submit a form or after they go to a new tab. In addition, you may want to ensure that the user data is available on the correct page or in the correct state. This could also get more complicated when the requirement of a back navigation is involved.

This section will teach you how to work with NavController and NavParams, which are the two important base classes to manage all navigation for the app. This is a screenshot of the app you will develop:

Navigating multiple pages with state parameters

This app has three different examples of how to navigate to a different page and how to pass the parameters. When you click on any button, it will show the second page, which is as follows:

Navigating multiple pages with state parameters

The second page, basically, captures the parameters and displays them on the screen. It also gives you three different options to navigate back...

Key benefits

  • Leverage Ionic 2 and its exciting new features to create cutting edge real-time apps
  • Work through simple recipes to address your problems directly and solve them effectively
  • Get examples at each step to guide you on your learning curve

Description

Developing real-time apps is the need of the hour, and apps that deal with humongous amounts of user data and real-time information that needs to be updated frequently are in high demand. Currently, one of the most popular frameworks for this task is Ionic Framework, which is undergoing a major makeover. This book will get you started with Ionic and help you create Angular 2 components that interact with templates. From there, you’ll work with Ionic components and find out how to share data efficiently between them. You’ll discover how to make the best use of the REST API to handle back-end services and then move on to animating the application to make it look pretty. You’ll learn to add in a local push notification in order to test the app. You’ll work with Cordova to support native functionalities on both iOS and Android. From there, you’ll get to grips with using the default themes for each platform as well as customizing your own. Finally, you’ll see how best to deploy your app to different platforms. This book will solve all your Ionic-related issues through dedicated recipes that will help you get the best out of Ionic.

Who is this book for?

This book is for front end JavaScript developers who know the basics of JavaScript programming. No prior knowledge of Ionic is required to get the most of this book.

What you will learn

  • Create custom UIs using Angular 2 directives
  • Make the best use of REST APIs to submit forms
  • Create beautiful animations and graphics in the application
  • Embed videos and other media into the app
  • Access native device functionalities such as a camera and maps using ngCordova
  • Theme the application based on the various platform styles available
  • Publish your application to a variety of platforms
  • Leverage Angular 2 events and Ionic-specific events to communicate

This book is definitely not for beginner. But the author made it so simple to understand the concepts in cookbook format. First you must be already familiar with JavaScript and Angular 1 already. Otherwise you will not understand some reference back to Ng-click or Ng-hide but again the author gave you a history and differences. It was not hard to follow at all if you spend time properly. Second I also found it is hard to get the initial setup right especially getting the app to be deployed to your phone. But Chapter 1 and 9 were so awesome to bring the level of details.

I am very familiar with Ionic 1 and the entire Cordova ecosystem. Frankly I didn't like the approach much due to some performance issues. However, Ionic 2 is amazingly fast to tell the least. A lot of screen hiccups during transitions are gone. Also now with Crosswalk for Android, you can eliminate a lot of "weird" bugs due to animation errors. I wrote a lot of large Enterprise-level applications and my take is that the author did a good job to explain basic simple concepts but also carry it to larger and more scalable scenarios. Using Angular 2 and TypeScript definitely put a lot of pressure on the developers to write code for larger team in the first place. Yes, newbies will see this as an entry barrier due to large amount of boilerplate. The author did a very fine job to continue from the previous version of this book to help the readers grasp new concepts quickly with new awesome examples. 5 stars!!

'm learning about Ionic for the second time as I have read the first version of this book. To be honest, it's almost full a re-written of the previous Edition. This is because I am so unfamiliar with Angular 2 and the new way to write code (using TypeScript now). So this book is so valuable for me as a learning resource to gain both knowledge about Angular 2 and Ionic 2. Once I understand the concept, I could get moving a lot faster with easy to follow examples from the author. Two thumbs up!!

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.
