Building web apps with Angular and TypeScript

Introduction to Angular

In this module you'll see what Angular is all about, and why it's one of the most popular platforms for modern web development.

• Evolution in Web App Development
• Basic Node.js and Angular project structure
• Angular Core and Modules
• TypeScript, Dart, Plain Old JavaScript

Strongly Typed JavaScript with TypeScript

Let's face it: JavaScript was never designed for big applications. Many constructs to tame complex code like interfaces and strong typing are completely absent. TypeScript brings these features to the developer; allowing you to write modern, application-scale JavaScript.

• Type-Safe JavaScript Development with TypeScript
• Typescript configuration
• Implementing Types, Classes and Inheritance

Core Concepts

In this module you'll get acquainted with the most important building blocks for any Angular application. This builds the foundation for all following chapters.

• Components
• Modules and Standalone Components
• Services
• Angular CLI and other Tools
• LAB - Creating an Angular Application

Data Binding

Data binding allows you to forget about the HTML while writing JavaScript code. It allows you to inject data into a view without creating a strong dependency between the two. This results into more flexible, testable and maintainable code.

• The Importance of Binding
• Component to View
• Structural Directives
• Local Template Variables
• Value Conversion
• View to Component
• LAB - Data Binding

Components

In this module we'll dive a bit deeper into Components. You'll learn how to create a hierarchy of components and how to communicate between them. You'll also take a look at some component libraries like Angular Material and how they can make you more productive.

• Using Multiple Components
• Input and Output
• ViewChild and ContentChild
• EventEmitter
• Directive Life Cycle
• Component Libraries
• LAB - Building components

Attribute Directives

A component always has a view. But what if you just want to add custom behavior to an existing element? In this module you'll explore some existing directives, and learn how to build your own.

• Attribute Directives
• Built-in Directives
• Building Custom Attribute Directives

Control Flow and Structural Directives

Templates need a form of control flow. You want to be able to dynamically add, remove or repeat elements in your template. Angular now has a built-in control flow syntax for this, with a fallback to structural directives for older versions. In this module you'll learn about the ins and outs of both methods.

• Built-in Control Flow: @if, @for, @switch
• Structural Directives: ngIf, ngFor, ngSwitch
• Tracking Items in for Loops
• Conditional Variables
• Deferrable Views
• Advanced Usage

Dependency Injection and Providers

Dependency Injection (DI) is the art of taking two strongly coupled objects and tearing them apart. This helps you write understandable, maintainable and testable code. It's not really a choice in Angular either: you have to do it. Angular has an entire mechanism based on Providers to support DI which you will explore in this module.

• Terminology
• Dependency Injection Basics
• Services
• Providers
• Factories
• Injection Tokens
• LAB - Building Services and using Dependency Injection

Pipes

Pipes are a convenient way to make little changes to values in a view. This includes formatting and filtering of data. It's easy to use and to extend the possibilities of pipes.

• Using a Pipe
• Built-in Pipes
• Custom Pipes
• Pure versus Impure
• LAB - Build your own Conversion Pipe

Working with Forms

Forms are essential to any app that allows you to manage data. You need to do more than just data binding. You need validation, automatic formatting, respond to data changes a so on. Angular provides two different approaches to dealing with this: Template-driven forms and Model-driven forms. This module will explore both.

• What's in a Form
• Responding to Changes
• FormBuilder
• Data Validation
• LAB - Capturing and Validating Input with Forms

Talking to the Server

This module will teach you how to retrieve and send data to your backend. We will focus on REST and use RxJS Observables to get the job done.

• Sending and Receiving Data
• HTTPClient Module
• HTTP Interceptors
• Observables versus Promises
• LAB - Communication with REST Web Services

Building a Single Page Application

Instead of hopping from one page to the next, you can design your website as a Single Page Application. This makes your website feel and perform more like an application. SPAs have many advantages, but are usually difficult to implement. This module will teach about the constructs available in Angular to build a SPA.

• What is a SPA
• Router Module
• Route Configuration
• Parent-Child Navigation
• Router Guards
• LAB - RECAP - Setting up a Complete Single Page Application with Routing
