How to use routing in Angular
Routing is an important part of any web application. It allows users to navigate between different pages and view different content. Angular is a popular JavaScript framework for creating web applications. It has a powerful routing system that makes it easy to create complex routing scenarios. In this tutorial, we will learn how to use routing in Angular.
Install the Angular Router
The first step in using routing in Angular is to install the Angular Router. This can be done using the npm package manager. To install the Angular Router, open a terminal window and run the following command:
npm install @angular/routerOnce the installation is complete, you can import the RouterModule into your application.
Import the Router Module
The RouterModule is the main module for routing in Angular. To import it into your application, open the app.module.ts file and add the following line:
import { RouterModule } from '@angular/router';Once the RouterModule is imported, you can configure the routes for your application.
Configure the Routes
The next step is to configure the routes for your application. This is done by creating an array of route objects. Each route object contains a path and a component. The path is the URL that the route will respond to, and the component is the component that will be rendered when the route is activated.For example, if you wanted to create a route for the home page of your application, you could create a route object like this:
const routes: Routes = [ { path: '', component: HomeComponent }];Once you have created the array of route objects, you can pass it to the RouterModule.forRoot() method. This method will configure the routes for your application.
Add the Router Outlet
The next step is to add the Router Outlet to your application. The Router Outlet is an Angular component that is used to render the components for the active route. To add the Router Outlet, open the app.component.html file and add the following line:
<router-outlet></router-outlet>This will render the component for the active route.
Add the Router Links
The last step is to add the Router Links to your application. The Router Links are used to navigate between the different routes in your application. To add the Router Links, open the app.component.html file and add the following line:
<a routerLink="/home">Home</a>This will create a link to the home page of your application. You can add as many Router Links as you need for your application.
Conclusion
In this tutorial, we have learned how to use routing in Angular. We have installed the Angular Router, imported the RouterModule, configured the routes, added the Router Outlet, and added the Router Links. With these steps, you can create complex routing scenarios in your Angular applications.
