This course has been updated! We now recommend you take the Angular Core course. Get a high-level overview of the major pieces of Angular 2 and learn how they fit together to create a powerful framework for building out applications.
Learn the differences between Angular 1 vs Angular 2. Use the Angular CLI to get started quickly. And compose large Angular 2 applications using services, routes, and subcomponents.
Plus, harness the awesome power of observables in your applications. This course and others like it are available as part of our Frontend Masters video subscription. Published: March 15, Lukas sets the course's first-day agenda to construct a single feature in AngularJS. Reviewing a demo application for the course, Lukas explains the importance of master—detail interface for learning coding as well as its importance for learning a new framework.
Lukas covers the features and benefits that are in Angular 2 over its previous version. Continuing to explain the various building blocks inside the Angular 2 framework, Lukas discusses Directives, Data Bindings, and Metadata. Lukas covers Services, specific tasks that can be used in Angular 2 components. In this challenge, students identify the major Angular 2 pieces in the sample application. Then create a new property to the Items component binding it to the view as well as another property to the ItemsService to be consumed by a component.
Lukas explores Angular 2 sample application, walking through the solution modern web apps with angular 2 download Challenge 1. Discussing the problems associated with the moving pieces involved in building JavaScript applications, Lukas covers how Angular CLI can streamline development.
Taking questions from students, Lukas walks through the solution to Challenge 2. Lifecycle hooks allow custom logic to be added at various component stages and are implemented as class methods.
Lukas shows lifecycle hooks on ngOnInit and ngOnDestroy, when a component is created and destroyed respectively. Lukas showcases how to create an Angular Component. In this challenge, students create a Widgets feature, modern web apps with angular 2 download. Using an ES6 class for the widgets component, import any necessary modules, decorate the component to use the widgets template, and display the widgets component in the home component.
Introducing interpolation, which is the process of binding to component properties both inside and outside of a template, Lukas discusses and demonstrates the different ways data can flow between components and templates: Property, Event, and Two-Way Bindings. Lukas reviews the Hashtag Operator that defines a local variable inside a template which is available to sibling and child elements. Lukas covers the Elvis Safe Navigation Operator that be used to guard against exceptions being thrown when a variable that does not exist is referenced.
In this challenge, students create a "widgets" template that contains a template expression via interpolation, a property binding, an event binding, and a two-way binding. Lukas walks through solution for Challenge 3 and takes questions from students.
Just like with components, services in Angular 2 are just a class. The API for a service is defined by creating methods on the class. Services are made available by adding the Injectable decorator. After they are properly decorated, they can be imported and consumed in any other component class.
In this challenge, you will create a widgets service class and a widgets collection. After introducing the challenge, Lukas spends a few minutes answering some audience questions.
Lukas walks through the solution for Challenge 4 and takes questions from students. Lukas discusses how Modern web apps with angular 2 download 2 handles routing covering the component router, navigating routes, query parameters, child routes, and named routes.
Reviewing first day's topics and taking questions from students, Lukas covers modules, routes, modern web apps with angular 2 download, components, and services in Angular 2. By making a review feature including file structure, component class, and template, students will create a project that covers concepts covered in the first day's material in this modern web apps with angular 2 download. Lukas walks through the solution for Challenge 5 and takes questions from students.
Going over a brief history of Angular, Lukas compares the architecture styles between Angular 1 and 2. Angular 2 has evolved to a component-based approach. He also describes many of the features and benefits of a component system architecture. Component contracts represent an agreement between software suppliers and consumers.
Inputs and outputs are defined and enforce how the Component will be consumed. Lukas covers on Input and Output decorators. The Output decorator also exposes an EventEmitter property that will dispatch an event to the parent component. While reviewing Input and Output decorators, Lukas takes questions from students. Lukas codes an example using an Output decorator and a custom EventEmitter. In this challenge, students create widgets-list and widget-details components using Input and Output, modern web apps with angular 2 download.
Lukas breaks down the solution into two parts. In this first part, he creates the widgets-list component, modern web apps with angular 2 download. Abstracting the templates, Lukas continues demonstrating the solution to Challenge 6 by creating the widget-details component. Before moving onto integrating forms, Lukas reviews data binding and component and answers students questions.
Lukas introduces the FormsModule, controls and validate styles in order to create and manage forms in Angular 2. Lukas demonstrates how to group and validate FormControls within a FormGroup. Adding custom CSS rules, Lukas shows how to modify the visual appearance of form controls when they are valid or not. To handle mutable operations, Lukas covers the concept of creating a local copy of an object that can update without letting the shared object be overwritten until the local copy is ready to be emitted.
In this challenge, students make a form for the widget-details component, bind the form to a widget object, and submit the modern web apps with angular 2 download to the parent component. Lukas covers the solution for Challenge 7 as well as demonstrates a couple of debugging techniques. Lucas takes a look at some the methods available in the API. An Observable is a lazy event stream which can emit events. A subject performs some logic and notifies the observer at the appropriate times.
After introducing Observables, Lukas compares modern web apps with angular 2 download to Promises. Then he talks briefly about the Headers object. Lukas creates a service that loads JSON. He then demonstrates that observables do not load any data from their endpoint until the subscribe method has been called. He also compares the behavior of observables to the promise-based fetch API.
Wrapping up the course, Lukas takes questions from students about his preference for Observable over Promise; how to keep a portion of a page from displaying until data comes from a service; potential memory concerns for Subscribe methods; and more.
