Migrating AngularJS App to Angular App

We all know Angular has had loads of improvements and has been designed from scratch. So, one of the most bugging questions among the Angular developers is how can we migrate existing AngularJS applications into Angular. In this chapter, we are going to discuss best practices, approaches, and tools recommended to successfully migrate existing AngularJS applications.

In this chapter, we will cover the following topics:

  • Migration process
  • Syntax difference
  • Benefits of upgrading to Angular
  • Rules for incremental upgrade to Angular
  • Incremental upgrading using UpgradeAdapter
  • Components migration
  • Roadmap from AngularJS to Angular

Migration process

AngularJS and Angular differ syntactically and conceptually. So the migration process involves code change not only on a syntactical level but also in implementation. The Angular team made the life of the developers easier by providing built-in tools in Angular for migrating AngularJS applications to Angular. There is some preliminary process to do in our existing AngularJS applications before starting up the migration process.

The preliminary process involves decoupling the existing code and making the existing code maintainable. This preliminary process not only prepares the code for upgradation, but will also improve the performance of the existing AngularJS applications.

We can follow an incremental approach by running both AngularJS and Angular in the same application and initiate the migration process one by one starting from the components. This approach...

Syntax difference between Angular and AngularJS

Angular has different syntax compared to AngularJS in many ways. Let us see few of them here.

Local variables and bindings in templates

A template is a view that deals with the UI part of an application that is written in HTML. First we will see the syntax differences for One-way Data Binding.

AngularJS:

<h1>Book Details:</h1> 
<p>{{vm.bookName}}</p> 
<p>{{vm.authorName}}</p> 

Angular:

<h1>Book Details:</h1> 
<p>{{bookName}}</p> 
<p>{{authorName}}</p> 

Both the code snippets show the One-way Data Binding that binds the book and author name to the UI using the double-curly braces. However, the AngularJS...

Benefits of upgrading to Angular

Let us see some of the benefits of upgrading to Angular:

  • Better performance: Angular supports faster change detection, faster bootstrap time, view caching, template pre-compilation, and so on.
  • Server-side rendering: Angular has been split up into an application layer and a render layer. This enables us to run Angular in web workers or even servers other than browsers.
  • More powerful templating: Angular introduces new template syntax that removes many directives and integrates better with web components and other elements.
  • Better ecosystem: The Angular ecosystem will eventually get better and more interesting in the future.

Strategies to upgrade to Angular

There are different upgrade strategies...

Rules for incremental upgrade to Angular

It will be easier to do an incremental upgrade if we adhere to the following set of rules:

  • Implement one component per file; it helps to isolate the components and migrate them one by one.
  • Apply modular programming and arrange the folder by features; this will enable the developers to concentrate on migrating one feature at a time.
  • Use a module loader; following the preceding rules, you will end up with a large number of files in a project. This creates the hassle of organizing the files and referring them in the correct order in the HTML pages. When you use a module loader such as SystemJS, Webpack, or Browserify, it enables us to use TypeScript built-in module systems. This enables the developers to import or export features explicitly and share them between various parts of the application in the code.
  • Install TypeScript first; it is...

Incremental upgrading using UpgradeAdapter

Incremental upgrading can be done seamlessly using UpgradeAdapter. UpgradeAdapter is a service that can bootstrap and manage hybrid applications that support both Angular and AngularJS code. UpgradeAdapter enables you to run both AngularJS and Angular code simultaneously. UpgradeAdapter facilitates interoperability between components and services from one framework to another framework. The interoperability in Dependency Injection, the DOM, and change detection will be taken care of by UpgradeAdapter.

Injecting AngularJS dependencies to Angular

We may come across a scenario where the business logic on AngularJS services or any built-in services, such as $location or $timeout, is to...

Components migration

Designing AngularJS applications by component centric is good practice rather than designing them by controller centric. If you had developed your application following this practice, then it will be easier for you to migrate. Component Directives in AngularJS will have their template, controller, and binding similar to Angular components. But make sure your AngularJS application Component Directives did not use the attributes such as compile, replace, priority, and terminal. If your application implemented Component Directives with these attributes then it is not liaising with Angular architecture. If your AngularJS application was developed using AngularJS 1.5 and the components are implemented using the component API, then you might have noticed the similarities in Angular components.

Roadmap from AngularJS to Angular

It is good to follow this roadmap in migrating AngularJS to Angular:

  • JavaScript to TypeScript
  • Installing Angular packages
  • Creating the AppModule
  • Bootstrapping your application
  • Upgrading your application service
  • Upgrading your application component
  • Adding the Angular router

Let us discuss them in detail in the following sections.

JavaScript to TypeScript

Start your migration process by introducing TypeScript, as you will be writing your code using TypeScript in Angular. Installing TypeScript into your Angular application is quite easy. Run the following command to install TypeScript from npm into your application and save the package information to package.json:

npm i typescript --save-dev...

Summary

Way to go! Loads of stuffs, isn't it?! We started learning about migration in Angular.

Then we have seen various approaches and best practices in migrating AngularJS to Angular applications.

Next we discussed incremental upgrading using the upgrade adapter.

Finally, we learned in detail about the roadmap in migrating from AngularJS to Angular.

In the next chapter, we will discuss Angular CLI, which is the command line interface for Angular.

Description

Got some experience of Angular under your belt? Want to learn everything about using advanced features for developing websites? This book is everything you need for the deep understanding of Angular that will set you apart from the developer crowd. Angular has introduced a new way to build applications. Creating complex and rich web applications, with a lighter resource footprint, has never been easier or faster. Angular is now at release 4, with significant changes through previous versions. This book has been written and tested for Angular release 4. Angular is a mature technology, and you'll likely have applications built with earlier versions. This book starts by showing you best practices and approaches to migrating your existing Angular applications so that you can be immediately up-to-date. You will take an in-depth look at components and see how to control the user journey in your applications by implementing routing and navigation. You will learn how to work with asynchronous programming by using Observables. To easily build applications that look great, you will learn all about template syntax and how to beautify applications with Material Design. Mastering forms and data binding will further speed up your application development time. Learning about managing services and animations will help you to progressively enhance your applications. Next you’ll use native directives to integrate Bootstrap with Angular. You will see the best ways to test your application with the leading options such as Jasmine and Protractor. At the end of the book, you’ll learn how to apply design patterns in Angular, and see the benefits they will bring to your development.

Who is this book for?

This book is for JavaScript developers with some prior exposure to Angular, at least through basic examples. We assume that you’ve got working knowledge of HTML, CSS, and JavaScript.

What you will learn

  • • Implement asynchronous programming using Angular
  • • Beautify your application with the UI components built to the material design specification
  • • Secure your web application from unauthorized users
  • • Create complex forms, taking full advantage of 2-way data binding
  • • Test your Angular applications using the Jasmine and Protractor frameworks for better efficiency
  • • Learn how to integrate Angular with Bootstrap to create compelling web applications
  • • Use Angular built-in classes to apply animation in your app

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.
