Requirements
  • Some understanding of web development is very helpful and a basic knowledge of JavaScript is highly recommended to follow the course.
  • This is a fast-paced, example-based video course packed with information from the basics of TypeScript and Angular 2 to writing code on the go. We start with TypeScript core concepts, move on to Angular building blocks, and finish up with a running application that can serve as a blueprint for further studying or production development. Although briskly paced, it covers all the key concepts of the technologies involved.
Description

Angular 2 is a web development framework focused on writing component-based applications. TypeScript allows us to develop applications in a higher language than JavaScript, avoiding common mistakes and leveraging the future features of JavaScript. The two make a great combination, helping us write maintainable, clean web applications’ code using the tools of our choice.

This course will get your well on your way to learning Angular 2 and TypeScript together. You will study and practice how to create Angular 2 components in TypeScript. When we are done, you will be able to set up the environment and create a full-fledged application that can consume and publish server data and allow users to interact with it.

We start out by setting up an environment to develop a TypeScript-based Angular application. You will study the object-oriented features of TypeScript and then jump straight into the key concepts of Angular 2. We will create a new project setup in Visual Studio 2015 using the ASP.NET vNext web project. Next,we’ll cover the creation of database and web API controllers that handle data operations using Entity Framework and SQL Server. Finally, we will create components, communicate with web services, and learn how to guide users through our application with menus and forms.

This course will take your web development skills to a new level, enabling you to author Angular 2 applications from scratch.

Introducing TypeScript
3 Lectures 20:09

This video provides an overview of the entire course.

Preview 05:22

We could continue using JavaScript to build web applications, but TypeScript offers many advantages while having few, if any, drawbacks. We will go over the uses, features, and benefits of the TypeScript language.

Features and Benefits of TypeScript
06:43

Although we could write TypeScript in Notepad and setup command-line tooling, this approach is far from productive. Although there are many editors available that support TypeScript, we will use Visual Studio 2015 to write TypeScript code.

Setting Up Our Environment

TypeScript Concepts
5 Lectures 52:00

Type safety is an important programming feature that JavaScript lacks. TypeScript brings type safety into web development.

Preview 12:31

We need to have an ability to break our application code into discrete units of work. This video will help us get started with the basic building block of the TypeScript web application, which is a class. We will create a class with properties and methods.

Your First Class
06:50

The need to write complex code and implement extensive logic in our methods is quite common. If the use cases for what methods should do and what parameters they take aren't clear, it may cause problems. We will take a closer look at the class' methods in this video.

Creating Advanced Methods
11:37

Sometimes, you want to share some specific functionality across many different classes. Inheritance helps us solve this problem by adding functions to base classes. At times, we want to rely on abstractions instead of concretions, and the interface is the feature in TypeScript that solves the problem.

Inheritances and Interfaces
14:33

Any time we write some code, we need an ability to debug it. We are talking about examining variables, setting breakpoints, and so on. Let's take a look at how we can use the browser tools to debug TypeScript.

Debugging TypeScript

Advanced TypeScript Concepts
5 Lectures 48:58

In order to increase the readability of our code, we want to use language constructs to name discrete values. We also want to have an ability to reuse variable names when appropriate.

Preview 08:24

Sometimes, creating an instance of a class is not necessary to call a method, but classes provide a nice way to encapsulate code. In this video, we will discuss how static methods and properties can help us write such code.

Working with Statics
09:08

Sometimes, we find ourselves writing duplicate code when defining properties and constructors. We also find ourselves with an inability to run additional code when a property is set. At times, we want to expose read-only properties. Let's look at how we can tackle this.

Advanced Properties
08:52

Arrays, the only collection objects in JavaScript, cannot be typed. This opens our code to a potential type safety problem. It would also be nice if we could reuse functions and classes without losing type safety in TypeScript.

Generics
12:02

Dealing with a pointer to "this" variable is an issue that has been present in JavaScript since the beginning. TypeScript has features that help us solve this problem.

Solving "this" Problem

Starting Angular 2 Application
5 Lectures 59:43

It is usually quite hard to get started with a new technology. Angular 2 is no exception. We will go through an overview of the Angular framework with a brief detour into version 1 but mostly covering the features of Angular 2.

Preview 07:43

One of the hardest things in learning a new technology is getting started and setting up the environment.

Setting Up the New Project
13:05

It is important to have a good understanding of the key classes we are going to write when creating an Angular application. We need to know the key parts of the Angular framework.

Overview of Key Angular 2 Concepts
09:45

A single Angular 2 application is a heavy client-side web application, and we need to create a starting page for it.

Creating the Shell Page
07:10

As the Angular 2 application consists of components, it is time for us to create our first component. It will have a property and a method so that we can look at data bindings in action.

Creating the First Component
22:00
+
Creating Web API Web Services
5 Lectures 42:14

Our Angular application needs to communicate with the server in order to get or persist data. We need to understand how to use a Web API for this purpose.

Preview 06:59

Our applications need to persist data as well as retrieve it. One of the most common storage options are relational databases. We need a technology to enable us to easily talk to databases. We need to learn Entity Framework to achieve this goal.

Brief Overview of the Entity Framework
05:05

We need to model our database in order to retrieve and persist the data. Entity framework allows us to create classes and configuration in order to do so.

Creating Entity Framework Classes and Configuration
12:20

Now that we know what the Web API is about, we need to create a controller, a web service that operates on our data. We should think about separating the concerns between controllers and data.

Creating API Controller to Handle CRUD Operations
09:49

Now that we have written the web service layer, we need to configure our application entry point, the start-up class. We need to configure the dependency injection for all the components of our app so that we can test what we have accomplished.

Configuring Application Start-up
08:01
+
Authoring Angular Components
4 Lectures 57:59

We need to get the data from the service to show in our application. We want to isolate the server communications at the same time. Let's create an injectable component responsible for exposing the server data to the rest of the application.

Preview 14:13

Now that we can get the data from the server, we need to present it to the user. We will create two components that do this.

Creating the Nested Components Which Use Services
17:03

Components in Angular 2 are designed to represent large portions of the user interface. They are not designed to manipulate DOM. If you need to adjust HTML, you should use directives to achieve this goal.

Creating a Directive
16:57

Sometimes, we want to format the data from our JSON objects differently than just displaying them as is in the UI. Pipes serve this exact purpose. As a part of data binding, we can transform the data on the way to the HTML.

Creating a Pipe
09:46
+
Navigation
4 Lectures 40:17

In a client-side application, we must still navigate between screens. In an Angular 2 application, navigation components handle menu-related features and general navigation tasks. We need to setup the necessary scripts and shell page as well as bootstrap client-side navigation. We must also setup a server to handle deep linking into client-side URLs.

Preview 06:11

Now that we know we need to define a structure of URLs that represents the views and components that our user will navigate to, we need to define these as routes.

Configuring Routes
12:45

Sometimes, we want to pass information to our components when navigating to them. We also want to have a way to organize routes logically into areas instead of putting all of them on the starting component. You will learn how to use route parameters to pass data to our components. We will also group our routes.

Nested Routes, Parameters, and Query Strings
08:02

Now that we have defined the routes, you need to learn how we can navigate to components that implement routes and where the data is displayed. You will learn how router outlets are placeholders for components and how we navigate via directives and in code. We will also take a look at how to handle missing routes.

Navigating with Directives and Code
13:19
+
Working with Forms
5 Lectures 01:02:24

How do we create forms that collect user input and provide validation? Angular forms make this process easy, while providing tools to control user input and dynamic validation with proper error messages and submission handling.

Preview 08:17

When we used jQuery in the past, we often found ourselves writing code to move data between HTML and models in JavaScript. Angular's data binding feature solves this problem. You will learn how we can create TypeScript models and bind them to the user interface

Form Data Binding
12:15

We need to ensure that the information we submit and persist based on user input is valid. When a user enters invalid information, we want to present the user with information pertinent to correcting the mistake made. We also want to keep the user from submitting invalid information to the server.

Simple Validation
09:16

Although we saw that we could make forms work without configuration using forms and the ngControl directive, we need to handle more complex use cases with custom validation. Forms based on control groups could be constructed in code, giving developers a lot more control over the forms and validation.

Reactive Forms
19:08

Sometimes we need to be notified that data changes in our model are based on user input. On the other hand, we want to notify the user when the system performs server calls. We will need to add listeners to monitor user changes. We will add visual feedback for the user when we persist data on the server.

Monitoring Changes and Using Notifications
13:28
+
Built-in Angular Building Blocks
5 Lectures 52:53

Quite often, we want to apply a different look to our application's pages based on the data that our application has. Angular 2 comes with two main components, NgClass and NgStyle, which allow us to easily change the user interface.

Preview 13:29

We often need to generate the same HTML element for items contained within a list, such as the TypeScript generic array. Angular 2 comes to our rescue by providing us with the ability to loop over an array specified in the HTML element to be used for each item.

Displaying Lists of Data
11:19

Sometimes, we want to suppress certain parts of the view based on the conditions contained in the component. We have a few tools at our disposal in order to hide or show items based on true/false conditions or even a specific value.

Conditionally Displaying Data
08:42

At times, we know that our data is static, and we want to optimize performance based on this fact. On the other hand, we may need to query components inside and outside the current component instead of resorting to direct HTML DOM manipulation. Angular 2 allows us to set a change detection strategy to optimize performance. It also gives us the ability to look around the current component for its children and parents in an abstract way.

Change Detection and Component Queries
09:21

So far, we have known the component to be instantiated when we design our app. At times, we need to decide which component we want to insert into a visual tree at runtime based on the state of our application. Angular 1 had the ngInclude directive for this purpose. Angular 2 comes with a component loader that is designed for this exact use case.

Dynamic Component Loading
10:02
+
Working with Server Data and Next Steps
4 Lectures 35:14

Promises have been used in Angular 1 to handle HTTP calls. Angular 2 relies on Rx or the Reactive Extensions framework to expose HTTP calls to the rest of the application. You will learn more about Rx and the key features it has.

Preview 07:27

We need to know how to make typical HTTP calls to update, insert, and delete data in our Web API controllers. We also need to be able to handle errors better. We will add the calls to add, update, and delete data following the HTTP REST standards.

Performing Insert, Update, and Delete Calls
11:05

As we make server calls, we want to indicate to the user that communication is taking place. We also want to add communication between components to coordinate the completion of HTTP calls. We will create a busy indicator control to use with our components. We will also add an output event to our child component to communicate with the parent when an HTTP call is complete.

Communicating Events between Components
07:25

Now that we know the key concepts of Angular 2 and the features of TypeScript as well as writing web services with .NET Core, we want to know what to concentrate on next. We will go over the additional functionality that exists in the frameworks. We will discuss the other steps we might follow to advance and solidify our learning.
