4 Days
Become immediately productive in the TypeScript-driven front-end framework, Angular. Recently updated for Angular 11+.
Prerequisites: Some familiarity with JavaScript and HTML programming required, as well as an understanding of Ajax, JSON and web services.
Topics
Key Topic Areas
In this four-day course, you will build an Angular application from the ground up.
01
Introducing ECMAScript and TypeScript
You’ll begin with a tutorial on ECMAScript and TypeScript, use the Angular CLI, and take a tour of some key features of the platform, including Angular’s module system.
02
Using Components
Learn the ins and outs of developing component templates, handle events, integrate with services, share data and events between components in the same component tree via inputs and outputs, and create directives to decorate components and other HTML elements to manipulate the DOM.
03
Showing Views with the Angular Router
Learn how to use the Router to separate applications into different navigable component trees, and how to create router elements across different application modules.
04
Reactive and Template Forms
Forms are a key part of Angular, and set it apart from React and other technologies. You’ll implement forms using both the ngModel template-driven API as well as the Reactive Forms API, and learn the benefits of each type. You’ll implement validations and handle error reporting in your forms.
05
The Benefits of Services
Learn to leverage Angular services to gather shared data and business logic. You’ll use the HttpClient service to fetch data and handle content updates, using the providedIn setting to automatically inject services without extra configuration, and use service tokens to inject various implementations of the same service.
06
Reactive Angular with RXJS
You’ll use the RxJS Observable API for handling user inputs, network responses, routing events, and other streams of active content. A firm grasp of RxJS is essential to getting the most out of Angular.
07
Learn How to Test Angular
You’ll learn how to test components, services, pipes, directives and other features using Jasmine and Karma, and the Angular testing APIs.
