Answer 1

Using the firebase_admin python module, follow the standard setup documented in the Cloud Firestore Docs This will involve calling initialize_app with a credentials context and then creating a traditional Firestore Client with firestore.client() For example: from firebase_admin import credentials, firestore, initialize_app firebase_credentials_file_path = ... cred = credentials.Certificate(firebase_credentials_file_path) initialize_app(cred) db = firestore.client() Next, you will need to install and run the Firestore Emulator, which will host the a local Firestore instance over localhost:8080. npx firebase setup:emulators:firestore npx firebase --token $FIREBASE_TOKEN emulators:start --only firestore --project $PROJECT_KEY Finally, inject a redirect in the already instantiated firestore.client instance to interact with the local emulator host/port using an insecure GRPC channel: import grpc from google.cloud.firestore_v1.gapic import firestore_client from google.cloud.firestore_v1.gapic.transports import firestore_grpc_transport channel = grpc.insecure_channel("localhost:8080") transport = firestore_grpc_transport.FirestoreGrpcTransport(channel=channel) db._firestore_api_internal = firestore_client.FirestoreClient(transport=transport) Now, your db object will interact with the local emulator without any problems.
