How to Get the Current Route (URL) in Angular

Angular is a popular JavaScript framework used for building dynamic web applications. One common functionality that developers often need is to get the current route or URL in Angular. In this tutorial, we’ll explore different methods for getting the current route in Angular and how to implement them.

Using the Router Service

Angular comes with a built-in Router service that allows us to render different components based on the URL. We can use this service to get the current route or URL as well. Here’s an example:


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

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
currentUrl: string;

constructor(private router: Router) {
this.router.events.subscribe((url: any) => this.currentUrl = url.url);
}
}

In the above example, we imported the Router service and subscribed to its events every time the URL changes. We assigned the current URL to the currentUrl variable and used it in the component.

Using ActivatedRoute

Another way to get the current route or URL is by using the ActivatedRoute service. It provides access to the current route’s parameters and data. Here’s an example:


import { Component } from '@angular/core';
import { ActivatedRoute } from '@angular/router';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
currentUrl: string;

constructor(private route: ActivatedRoute) {
this.route.url.subscribe((url: any) => this.currentUrl = url[0].path);
}
}

In the above example, we imported the ActivatedRoute service and subscribed to its URL observable. We assigned the first element of the URL array to the currentUrl variable and used it in the component.

Using Location Service

We can also use the Location service to get the current route or URL. It provides information about the current browser URL. Here’s an example:


import { Component } from '@angular/core';
import { Location } from '@angular/common';

@Component({
selector: 'app-root',
templateUrl: './app.component.html',
styleUrls: ['./app.component.css']
})
export class AppComponent {
currentUrl: string;

constructor(private location: Location) {
this.currentUrl = this.location.path();
}
}

In the above example, we imported the Location service and used it to get the current path using the path() method. We assigned the path to the currentUrl variable and used it in the component.
