Firebase

The Firebase plugin provides three key capabilities:

• Firestore Vector Store — Native vector similarity search for RAG applications.
• Cloud Functions Deployment — Deploy Genkit flows as scalable Cloud Functions with auth and streaming.
• Telemetry — Export traces and metrics to Google Cloud observability.

Installation

<dependency>
    <groupId>com.google.genkit</groupId>
    <artifactId>genkit-plugin-firebase</artifactId>

Telemetry

Export traces and metrics to Google Cloud observability (Cloud Trace, Monitoring, Logging):

FirebasePlugin.builder()
    .projectId("my-project")
    .enableTelemetry(true)
    .forceDevExport(true)  // Also export in dev mode
    .build()

Required GCP APIs

Enable these APIs in your Google Cloud project:

• Cloud Trace API
• Cloud Monitoring API

Requirements

• Firebase project on the Blaze (pay-as-you-go) plan
• Application Default Credentials or a service account JSON
• GCLOUD_PROJECT or GOOGLE_CLOUD_PROJECT environment variable (auto-detected)

Sample

See the firebase sample for a complete RAG pipeline with Firestore vector search and a Cloud Functions deployment example.
