Navigate & NavigateByUrl: A Brief Overview on Navigating Routes in Angular

Introduction

In Angular, routing is a fundamental concept for building single-page applications. Angular provides several tools to help navigate between pages or components, including the Navigate and NavigateByUrl methods. In this article, we will go through what these methods are, how they work and how they can be used in your Angular app.

Navigate Method

The Navigate method is a built-in method of the Angular router that allows you to handle navigation to a specified route programmatically. It takes a route path as a string value or an array of segments with parameters.

For instance, if we want to navigate to the ‘home’ route programmatically, we can use the following code:


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

constructor(private router: Router) {}

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

In the above code, we first import the Router from the ‘@angular/router’ module. Then, we inject it into the constructor and use it to navigate to the ‘home’ route programmatically on the ‘onNavigateHome’ method call.

NavigateByUrl Method

The NavigateByUrl method is also a built-in method of the Angular router that allows you to navigate to a specified URL programmatically. It takes a URL as a string value in the form of ‘/path?query=string#fragment’.

For instance, if we want to navigate to the ‘home’ route with a query parameter in the URL programmatically, we can use the following code:


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

constructor(private router: Router) {}

onNavigateHome() {
this.router.navigateByUrl('/home?from=page1');
}

In the above code, we use the Router to navigate to the ‘home’ route with a query parameter ‘from=page1’ in the URL programmatically.

Navigate Routes with Parameters

Angular allows us to navigate to routes with parameters in a query string or route parameter. We can use the Navigate method or NavigateByUrl method to navigate to these routes programmatically.

For instance, if we have a ‘user’ component that displays user details, we can navigate to this component with a route parameter ‘userId’ like below:


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

constructor(private router: Router) {}

onNavigateUser(userId: number) {
this.router.navigate(['/user', userId]);
}

In the above code, we pass the ‘userId’ parameter as an argument to the ‘onNavigateUser’ method to navigate to the ‘user’ component with the ‘userId’ parameter.

FAQs

What is an Angular route?

An Angular route is a URL path that can be used to navigate between different views or components in a single-page application.

What is the difference between Navigate and NavigateByUrl methods?

The Navigate method is used to navigate to a specified route path programmatically, while the NavigateByUrl method is used to navigate to a specified URL path programmatically.

Can we navigate to a route with parameters in Angular?

Yes, we can navigate to routes with parameters in Angular using either the Navigate method or NavigateByUrl method.

How can we pass parameters to a route in Angular?

We can pass parameters to a route in Angular using either a query string or route parameter. We can access these parameters in the component using the ActivatedRoute service.

What is the significance of parameters in an Angular route?

Parameters in an Angular route can be used to pass data between different views or components. It allows us to create dynamic and interactive user interfaces in single-page applications.
