Creating routes and navigating between routes



Routing in Angular: A Comprehensive Guide to Creating Routes and Navigating Between Routes



Angular is a popular open-source web application framework used for developing dynamic single-page applications. Routing is one of the most important features of Angular and is used to create navigation paths between the different components of an application. In this guide, we will go over how to create routes and navigate between them in Angular.



Prerequisites



Before you can get started, you will need to have a basic understanding of TypeScript and ES6. Additionally, you will need to have an Angular project setup. If you need help setting up an Angular project, you can follow the instructions here.



Creating Routes



In order to create routes in Angular, we will need to use the RouterModule in our project. First, we need to import the RouterModule from the @angular/router package. We can do this by adding the following line to the top of the file where we want to use the RouterModule:



import { RouterModule } from '@angular/router';


Next, we will need to create an array of route configuration objects. This array will contain information about the different routes we want to create. Each object in the array will have the following properties:




  • path: The path of the route that will be used to access the route.

  • component: The component that will be used for the route.

  • data: (Optional) Any data that needs to be passed to the component when the route is accessed.



Once we have our array of route configuration objects, we can pass it to the forRoot() method of the RouterModule. This will create the routes in our application. We can do this by adding the following line to our file:



@NgModule({
  imports: [
    RouterModule.forRoot(routes)
  ],
  ...
});


Where routes is the array of route configuration objects we created earlier.



Navigating Between Routes



Once we have our routes setup, we can use the Router service to navigate between them. We can do this by injecting the Router service into our component and calling the navigate() method. This method takes an array of route paths as an argument. For example, if we wanted to navigate to the /home route, we could do so by calling the navigate() method like this:



this.router.navigate(['/home']);


Tips




  • It is best practice to create a separate file for your routes so they are easy to maintain.

  • You can use the RouterLink directive to create links between routes in your template.

  • You can use the queryParams property to pass data to a route.

  • You can use the fragment property to navigate to a specific section of a route.



Conclusion



In this guide, we have gone over how to create routes and navigate between them in Angular. We discussed how to use the RouterModule to create routes and how to use the Router service to navigate between them. Additionally, we included some tips to help you get the most out of routing in Angular.
