Angular with Relaunch

This course will teach you step-by-step how to design and architect large Angular applications. 

You’ll start with the basics: components, pipes, and directives. These are the building blocks of any Angular application, so you will get plenty of hands-on practice with this material. Next, you’ll ramp things up by stepping into modules, routing, and RXJS, where you’ll learn how to declaratively manage data and dive deep into observables.

In the latter half of the course, you’ll cover reactive and template forms (crucial for handling user data), as well as custom validators and setting up authentication with Firebase.

By the end of this course, you'll be able to design large, scalable applications, be able to develop rich interactive components, and you’ll really understand how Angular works under the hood.

Angular: Designing and Architecting Web Applications

It's time to handle the errors when the registration fails. According to the documentation for the `createUserWithEmailAndPassword` method, Firebase will provide error codes as to why the registration failed. We're going to keep things simple by creating one message to handle all errors from the request.

First, we need to tell Angular that there's an error in our form. This was something taken care of for us when we used validators. There will be times where we'll want to throw errors outside of a validator. We can throw errors using the `setErrors` method on form controls or form groups. 

This will add an error object to the `errors` object on the control or group on which we're calling it. Let's try using it in the `register` method. Update the `register.component.ts` component class file to the following:

In this lesson, we'll learn how to generate custom errors.
