Usage

// in the firebase cloud functions

import * as admin from 'firebase-admin';
import * as functions from 'firebase-functions';
import { FirestoreCloudService, QueryBuilder } from 'simplyfire';

const fsService = FirestoreCloudService.getInstance(admin);

export const purgeUnusedUsers = functions.pubsub.schedule('every 24 hours').onRun(async () => {
  const qb = new QueryBuilder();
  qb.where('isEmailVerified', '==', false);
  qb.where('lastSignInTime', '<', new Date(Date.now() - 60 * 24 * 60 * 60 * 1000));

  return fsService.bulkDelete('users', qb);
});


// in the client (with Angular)

import { QueryBuilder } from 'simplyfire';
import { FirebaseService } from 'simplyfire/ngx';

@Injectable({
  providedIn: 'root'
})
export class UserService {

    constructor(private firebaseService: FirebaseService) {}

    async getUsers() {
        const qb = new QueryBuilder();
        qb.where('isEmailVerified', '==', true);
        qb.limit(20);

        qb.leftJoin('companyId', 'companies', 'company');
        qb.leftJoin('lastPostId', 'posts', 'post');

        return await this.firebaseService.collection(`users`, qb);
    }
}
