Failed to connect to a new db under same project other than default

[chriskimgts]

Hi, do you support connecting to multiple dbs under same project? it doesn't look like it at the latest version. google forestore supports multiple dbs under a same project now.

If planned to support it in future, when would that be happening? If I am wrong, please let me know.
Thanks,

Chris

How to reproduce these conditions

put a new database name into datbaseURL:

Failing test unit, Stackblitz demonstrating the problem

Provide a failing test unit, or create a minimal, complete, and
verifiable example (http://stackoverflow.com/help/mcve) using
StackBlitz (https://stackblitz.com/edit/angular-fire-start).

Steps to set up and reproduce
enter a new database name into datbaseURL: Ex) databaseURL: 'https://test.firebaseio.com' (test is name of db)

Sample data and security rules

Expected behavior

What is the expected behavior?
If dabaseURL is put such as databaseURL: 'https://test.firebaseio.com', it should connect to the test database.

Actual behavior

What is the actual behavior?
it connects to default db currently.

Hey @chriskimgts! Can you please provide a reproducible example in StackBlitz? That would make it much easier for me to debug.

[chriskimgts]

Sorry I can't provide my app id and project id to StackBlitz. But I can explain since it is simple code.

I have two databases; default and test for an example under same project id called test-project. And I want to access test database.
So I defined angularFireConfig such as below

angularFireConfig: {
    apiKey: 'yourapikey',
    projectId: 'test-project',
    databaseURL: 'https://test.firebaseio.com',
},

And added AngularFireModule.initializeApp(environment.angularFireConfig), to @NgModule({
imports: ....
But when in my component I try to

     this.firestore
        .doc<{ version: string }>('settings/version')
        .valueChanges()
        .subscribe({
            next: ({ version }) => {
                console.log(version);
            },
            error: error => {
                console.error('Error fetching version data:', error);
            },
        });

It failed to access the test db. btw I was able to access default db with angularFireConfig: {
apiKey: 'yourapikey',
projectId: 'test-project',
},

Please let us know if something is missing

It seems that what you're trying to achieve would not be possible using angularFire. You see, It happens that I have the same issue: I want to create a dev database environment for my team's development. We're running a Blaze (paid plan) firebase project for this and I happened to find that article.

That article refers to create multiple Firestore databases in Google Cloud. Google Cloud project is not actually the same as the firebase Project. Yes, when you create a firebase project, it creates a google cloud project, but Firebase only knows about the default database:

Firebase	Google Cloud
Default FS DB	Default FS DB
	Second FS DB

I'm not really sure if this is 100% true. So, please: Anyone with the knowledge of angularfire's code help us to clarify this!

If angularfire can only connect to firebase (and not google cloud), then you need to find a way to connect the angular project to the google cloud's firestore database natively

Hi, @_davideast would you confirm if we can not access different dbs other than default db under same project yet? Thank you.

Here's how I managed to connect to a non-default database in the same project:

I rewrote all queries I have to use the modular syntax, and refactored away from all things compat.

import { getApp, initializeApp, provideFirebaseApp } from "@angular/fire/app";
import { initializeFirestore, provideFirestore } from "@angular/fire/firestore";

@NgModule({
  imports: [
    provideFirebaseApp(() => initializeApp(config)),
    provideFirestore(() => {
      const app = getApp();
      const dbName = "db-name";
      const providedFirestore = initializeFirestore(app, {}, dbName);
      return providedFirestore;
    }),
  ]
})

Then in your services:

import { inject } from "@angular/core";
import { Firestore, getDocs } from "@angular/fire/firestore";
import {
  collection,
  query,
  where,
  orderBy,
} from "@angular/fire/firestore";

@Injectable({
  providedIn: "root",
})
export class MyService {
  private firestore: Firestore = inject(Firestore);

  getUsers() {
    return getDocs(
      query(
        collection(this.firestore, "Users"),
        where("some_id", "==", "id"),
        orderBy("created_at", "asc")
      )
    );
  }
}

You can also initialize more databases, and inject them as needed.
