To share data between components in Angular using services, use the following step:

1. Create a Shared Service

Use a BehaviorSubject or Subject to store and emit data.

Provide methods to update and access the data.

Example:

import { Injectable } from '@angular/core';

import { BehaviorSubject } from 'rxjs';

@Injectable({ providedIn: 'root' })

export class DataService {

  private dataSubject = new BehaviorSubject<any>(null); // Holds the data

  data$ = this.dataSubject.asObservable(); // Observable to subscribe to


  updateData(data: any) {

    this.dataSubject.next(data); // Update the data

  }

}
