Add the module in app imports with project settings

@Module({
  imports: [
    FirebaseModule.forRoot({
      apiKey: "API_KEY",
      authDomain: "PROJECT_ID.firebaseapp.com",
      projectId: "PROJECT_ID",
      storageBucket: "PROJECT_ID.appspot.com",
      // Optional name of the app to initialize. Custom name for the Firebase App. The default value is "[DEFAULT]"
      // appName: "APP_NAME",

This module is a simple wrapper on Firebase API and export 3 services.

Cloud Firestore
Storage
Authentication

Cloud Firestore

Exposes most of Firebase firestore web api in the service.

// Add document example

it("should addDoc", async () => {
  const users =
    firestoreService.collection("users").withConverter < User > userConverter;

  const doc = (await firestoreService.addDoc) < User > (users, u1);

  const snapshot = await firestoreService.getDoc(doc);
  expect(snapshot.data()).toMatchInlineSnapshot(`
    User {
      "age": 1,
      "firstName": "fn1",
      "lastName": "ln1",
    }
  `);
});

See firestore.service.spec.ts for detailed usage.

Storage

Exposes most of Firebase storage web api in the service.

// Upload string and get download url example
it(`should upload string`, async () => {
  const fileName = "file.txt";
  await storageService
    .uploadString(fileName, "text content", "raw", {
      contentType: "text/plain",
    })
    .then((snapshot) => {
      expect(snapshot.metadata.contentType).toMatchInlineSnapshot(
        `"text/plain"`
      );
    });

  const downloadUrl = await storageService.getDownloadURL(fileName);
  expect(downloadUrl).toMatchInlineSnapshot(
    `"http://localhost:9199/v0/b/default-bucket/o/file.txt?alt=media&token=86739ce5-a96e-41ad-b807-e05b12e36516"`
  );
});

See storage.service.spec.ts for detailed usage.
