Allow to pass data with router.navigate

Explanation of the problem

The submission is a feature request to address a current limitation in Angular. The issue at hand is the absence of a built-in mechanism in Angular to pass additional data when using the router.navigate method. Several related issues have been raised in the Angular repository, but unfortunately, they were closed without being resolved. These issues, such as #5217, #8515, #9804, and #10248, highlight the need for the ability to pass data along with navigation.

The expected behavior, as proposed in #5217, suggests extending the router.navigateByUrl method to accept an additional parameter for data:

this.router.navigateByUrl('/path', { data: { entity: 'entity' } });

With this enhancement, the provided data should be accessible across various parts of the application where route.data is available, including the target component and any associated resolvers.

The issue affects Angular versions 2 and above. While a workaround in the form of a library called Angular2-navigate-with-data has been suggested by user @Hipparch, it would be beneficial to have a native solution integrated into Angular to address this limitation effectively.

Problem solution for: Allow to pass data with router.navigate

To address the issue of passing additional data with router.navigate in Angular, one possible solution is to leverage query parameters to carry the required information. This approach allows us to append data to the URL and extract it in the target component or resolver.

Here’s an example of how you can implement this solution:

1. When navigating, encode the additional data as query parameters:

const data = { entity: 'entity' };
const queryParams = new URLSearchParams(data).toString();
this.router.navigate(['/path'], { queryParams });

2. In the target component, extract the data from the query parameters:

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

constructor(private route: ActivatedRoute) {}

ngOnInit() {
  this.route.queryParams.subscribe(params => {
    const data = params as any; // Cast the params to the desired data type
    // Use the extracted data as needed
    console.log(data.entity);
  });
}

By encoding the data as query parameters and extracting them in the target component, you can achieve the desired functionality of passing additional information during navigation in Angular.

It’s important to note that this solution requires appropriate encoding and decoding of data to handle special characters or complex objects. Additionally, consider the security implications when passing sensitive information via query parameters and ensure proper validation and sanitization.

private dataSubject = new BehaviorSubject<any[]>([]);
data$ = this.dataSubject.asObservable();

<ng-container *ngIf="data$ | async as data">
  <div *ngIf="data.length > 0">
    // Display data here
  </div>
</ng-container>

import 'zone.js/testing';

beforeEach(() => {
  (window as any)['Promise'] = Promise;
});

@Injectable({ providedIn: 'root' })
export class SharedService {
  // Shared logic here
}

@Component({...})
export class ComponentA {
  constructor(private sharedService: SharedService) {}
  // Use the shared service here
}

@Component({...})
export class ComponentB {
  constructor(private sharedService: SharedService) {}
  // Use the shared service here
}

import { Component, Input } from '@angular/core';

@Component({
  selector: 'app-button',
  template: `
    <button [class]="classes">
      {{label}}
    </button>
  `
})
export class ButtonComponent {
  @Input() label: string;
  @Input() classes: string;
}
