Course Description

In recent years a lot of effort has gone into making HTML and JavaScript a better place for web apps rather than just web content. With Angular, you can exploit these new and modern concepts to take it to the next level. By using a componentized approach, Angular is better equipped than ever to build performant data-driven web-apps. While Angular takes care of data binding, navigation and server communication; TypeScript allows you to use the most advanced features JavaScript has to offer on any browser. Features like strong typing make your application more maintainable, better structured and flexible. This course is constantly being updated to the latest version of Angular, currently Angular 6. Enjoy this beautiful synergy between Google's Angular and Microsoft's TypeScript.

Target Student

This course targets professional web developers who are looking for a kick-start into the world of Angular and TypeScript. Participants of this course need to have a good understanding of JavaScript, HTML and CSS and a notion of node.js and npm.

Performance-Based Objectives

Set up and write application with TypeScript.
Create and manage Angular applications.
Use data binding to update your screen.
Split up complex interfaces into components.
Write their own directives and pipes.
Create complex forms with validation.
Communicate with a REST backend.
Write an Single Page Application with client-side routing.

Pre-requisites

Before attending this course, students must have:

A good understanding of JavaScript.
Basic understanding of HTML and CSS.
At least a notion of node.js and npm. An IDE for web development like Visual Studio Code or WebStorm.

Course Content

Module 1: Introduction to Angular

In this module you'll see what Angular is all about and why it is so important in modern web development.

Lessons

Evolution in Web App Development
Angular Core and Modules
TypeScript, Dart, Plain Old JavaScript

After completing this module, students will be able to:

Have an understanding of modern web UI technologies and the role they play in modern development.

Module 2: 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. And many of the new cool JS features are not implemented in current browsers. TypeScript is the solution to both problems; allowing you to write modern, application-scale JavaScript.

Lessons

Writing Application-Scale JavaScript
Type-Safe JavaScript Development with TypeScript
Implementing Types, Classes and Inheritance
Namespaces and Modules

Lab : Toy Store

Getting started with a TypeScript project
Making the models: Product, Category, Order
Creating the ShoppingCart
Using an external library
Adding the code to the HTML page

After completing this module, students will be able to:

Have an understanding of the benefits of TypeScript
Use core features of TypeScript
Set up a new TypeScript project
Compile and run TypeScript project

Module 3: Core Concepts

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

Lessons

Components
Modules
Services
Tools

Lab : Inspecting a First Project

Opening an running the project
Elements of an applications
Loading Modules
tsconfig.json

After completing this module, students will be able to:

Understand the goal of Components and Services.
Group Components and Services into Modules. Work with Angular Tools.

Module 4: 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.

Lessons

The Importance of Binding
Component to View
Structural Directives
Local Template Variables
Value Conversion
View to Component

Lab : TaskManager with Data Binding

Modules
Displaying a list of tasks
Style
Adding a Task

After completing this module, students will be able to:

Create and update a view using data binding.
Handle user interactions in a component.
Refer to elements with local template variables.
Use pipes for value conversion.

Module 5: 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.

Lessons

Using Multiple Components
Input and Output
ViewChild and ContentChild
EventEmitter
Directive Life Cycle

Lab : TaskManager: Using Multiple Components

Adding some style
TaskCreator component
TaskCard component
TaskList component
App component
Registering components

After completing this module, students will be able to:

Split up complex components into multiple components
Set up parent-child communication
Work with various life cycle hooks

Module 6: Attribute Directives

What if you want to add custom behavior to an existing element? In this module you'll explore existing directives like NgClasses and NgStyle; and learn how to build your own.

Lessons

What are Attribute Directives?
Built-in Attribute Directives
Custom Attribute Directives

After completing this module, students will be able to:

Understand the role of attribute directives.
Use built-in attribute directives.
Create your own attribute directives.

Module 7: Structural Directives

With structural directives you can change the flow in your HTML. For example, how do you generate HTML dynamically based upon your data without having to write HTML in your JavaScript?

Lessons

What are Structural Directives?
Built-in Structural Directives
Templates
Custom Structural Directives

After completing this module, students will be able to:

Understand the role of structural directives.
Use built-in structural directives.
Create your own structural directives.

Module 8: 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.

Lessons

Terminology
Dependency Injection Basics
Services
Providers
Factories
Injection Tokens

Lab : Creating a Task Service

Implementing the Service
Providing the service
Updating the AppComponent
Replacing the mock service with a real service

After completing this module, students will be able to:

Create their own services.
Work with the various providers in Angular.
Inject services into components and other services.

Module 9: 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.

Lessons

Using a Pipe
Built-in Pipes
Custom Pipes
Pure versus Impure

Lab : Temperature Pipe

Create a pipe for displaying temperatures in Kelvin, Celsius and Farenheit
Use your newly created pipe

After completing this module, students will be able to:

Use built-in pipes.
Create their own pipes.
Understand the importance of pure pipes.

Module 10: 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.

Lessons

What's in a Form
Responding to Changes
FormBuilder
Data Validation

Lab : Task Editor Form

The TaskEditor component
Basic Validation
Multiple validators
Custom validators

After completing this module, students will be able to:

Choose between template-driven and model-driven forms.
Create a form and submit the information.
Add validation and visual feeback.

Module 11: 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's Observables to get the job done.

Lessons

Sending and Receiving Data
HTTPClient Module
HTTP Interceptors
Observables versus Promises

Lab : Working with Observables

Update Components wot work with observables

Lab : Talking to the Server

Providing the HttpClient Module
Implementing the HTTP service

After completing this module, students will be able to:

Work with HttpClient to make rest calls.
Process the result with observables.

Module 12: 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.
