Get current route without parameters

I need to get my current route without params in Angular 2, I found a way to get the current route with params as follows:

 this.router.url

and then split it:

 this.router.url.split(';')[0]

But this looks as workaround, I think there should be better way?

To get current route without query parameters, you can use below mentioned single line:

this.router.url.split('?')[0] 

parseTree from Router helps fetching the segments without any knowledge about url structure.

import { Router } from '@angular/router';
...
constructor(private router: Router) {}
...
const urlTree = this.router.parseUrl(url);
const urlWithoutParams = urlTree.root.children['primary'].segments.map(it => it.path).join('/');

Start from here. If you have secondary outlets adjust as required.

For me, this is the cleanest solution I managed to do. I hope it helps

import { Router } from '@angular/router';
    
constructor(private router: Router){}

getUrlWithoutParams(){
   let urlTree = this.router.parseUrl(this.router.url);
   urlTree.queryParams = {}; 
   urlTree.fragment = null; // optional
   return urlTree.toString();
}

Short and simple pure js.

location.pathname

Native javascript will work to split the url into logical parts. Check out the "location" (or window.location) object. For example, using location at the url https://example.com/pathname1/pathname2?queryParam1=1&queryParam2=2 yields

location.origin === 'https://example.com/pathname1/pathname2'
location.href === 'https://example.com/pathname1/pathname2?queryParam1=1&queryParam2=2'
location.pathname === '/pathname1/pathname2'
location.search === '?queryParam1=1&queryParam2=2'

If you are using webpack, you can use the url polyfill module which comes bundled, along with the Angular Router module.

import { Component, OnInit } from '@angular/core';
import { Router } from '@angular/router';
import * as url from 'url'

@Component({
  selector: 'app-component',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.scss']
})
export class AppComponent implements OnInit {

  public constructor(public readonly router: Router) {}

  public ngOnInit() {
    const urlInfo = url.parse(this.router.url)
    console.log(urlInfo.pathname)
  }
}

I had a similar requirement, depending on which route I used to get the component I wanted different outcomes.

I found that activatedRoute.routeConfig.path was a great option and made it easy for me to see which route had been used.

constructor(private activatedRoute: ActivatedRoute) {}
ngOnInit() {
  if (this.activatedRoute.routeConfig.path === 'heroes/:id')

this could help you:

1. Import Router:

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

2. Signature in the constructor:

   constructor(private _router: Router) {}
   

3. Check the _router events property:

   this._router.events
       .subscribe(
           (url:any) => {
               let _ruta = "";
               url.url.split("/").forEach(element => {
                   if(element!=="" && _ruta==="")
                       _ruta="/"+element;
                   });
               console.log("route: "+_ruta); //<<<---- Root path
               console.log("to URL:"+url.url); //<<<---- Destination URL 
               console.log("from URL:"+this._router.url);//<<<---- Current URL
           }); 
   

To get current route without query parameters, you can use below mentioned single line:

this.url = this.url.substr(0, this.url.lastIndexOf("?"));

In my case I needed to compare the previous route and the new route, when changing only the :id on the url via router.navigate. Since I wanted the path without the different ids, I got the original path of the route:

/* 
    Routes = [
        { path: 'main/details/:id', component: DetailComponent }
    ]

    previousRoute = '/main/details/1'
    newRoute      = '/main/details/2'
*/

this.routeSubscription = this.router.events.filter((event) => event instanceof ResolveStart)
                                           .pairwise() // returns previous and current events
                                           .subscribe((ev: [ResolveStart, ResolveStart]) => {
    
    let sameRoute = ev[0].state.root.firstChild.routeConfig.path == ev[1].state.root.firstChild.routeConfig.path ?
                       ev[0].state.root.firstChild.routeConfig.path : undefiend;
    if (sameRoute) {
        // Same routes, probably different ids 
        console.log(sameRoute) // gives 'main/details/:id'
    } else {
        // Different routes
    }
});

I use locationStrategy like in accept answer but with .split() method. LocationStrategy work perfect in Angular 4 & Angular 5;

import {LocationStrategy} from '@angular/common';

export class MyService {
    constructor(private locationStrategy: LocationStrategy) {
    }

    public getUrl(filters: FilterConfig[]): void {
        const url = this.locationStrategy.path();
        const urlArray = url.split('?');

        return urlArray[0];
    }
}

One more things you should carry about is to be sure that your <router-outlet> is properly initialize before you try to get locationStrategy.path(). If <router-outlet> isn't initialize any Angular services can't return URL and query params properly.

To be sure that you location strategy is initialize you can use subscribe method like:

this.router.events.subscribe((evt) => {
...
}

But in this case you trigger your function on each router change so you need to protect this case if it's unwanted.

None of these worked for me.

There are many approaches to this, but in this case a guard was in place to stop users going to specific URL's. This worked fine except when URL's had parameters as the passed URL always contained all the parameters.

E.G: myPage/param1/param2

Or: myPage?param1=1&param2=2

In this case I'd want just myPage.

I coded the below, I don't like it, I'm sure it can be improved but haven't found anything else that works so far:

    let url: string = state.url;
    let urlParams: string[];

    if (url.includes("?")) {
        url = url.substr(0, url.indexOf('?'));
    } else {
        urlParams = route.url.toString().split(';')[0].split(',');

        if (urlParams.length > 1) {
            urlParams.shift(); // Remove first element which is page name

            // Get entire splitting on each param
            let fullUrlSegments: string[] = state.url.split('/');
            // Remove number of params from full URL
            fullUrlSegments = fullUrlSegments.slice(0, fullUrlSegments.length - urlParams.length);

            url = fullUrlSegments.join('/');
        }
    }

    alert(url);

state.url comes from the implementation for CanActivate (or inject Router).

canActivate(route: ActivatedRouteSnapshot, state: RouterStateSnapshot) Observable<boolean> { ... }

You could use URL https://developer.mozilla.org/en-US/docs/Web/API/URL/URL

const url = new URL("https://example.org/route/test?test")
const path = url.origin + url.pathname

But does not work in Internet Explorer.
