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

There's one more route we're going to add. Currently, the user can navigate around with the links. What if they navigate to a page that doesn't exist? Try to input a random path in the address bar.

If they attempt to navigate to a page that doesn't exist, the application will throw an error. It's telling us that the path doesn't match any of the routes registered in the application. Typically, most applications and sites will display a 404 not found page if we visit a resource that doesn't exist. We'll want to do the same.

# Wildcards

Wildcard routes are routes that can capture any route. This is useful for capturing routes that don't exist in our application. A wildcard route can be added using two asterisks (`**`). 

# Creating a new component

We'll create a component to handle the 404 page. In the command line, run the following command:

```bash
ng generate component PageNotFound
```

We're not tying the component to any specific module. It will be registered to the `app` module. It's not necessary to have an entire module for a 404 page because they tend to be simple. 

# Defining the route

When we scaffolded the project with the router, a routing module accompanied the `app` module. In the `src` directory, there should be an `app-routing.module.ts` file. Open it and update it to the following:

In this lesson, we'll learn how to set up wildcard routes to capture routes that don't exist.
