durable-streaming-firestore

Overview ¶

This sample demonstrates durable streaming with Firestore backend. Unlike in-memory streaming, Firestore-backed streams survive server restarts and can be accessed across multiple server instances.

Prerequisites:

• Firebase/GCP project with Firestore enabled
• Run: gcloud auth application-default login
• Set: export FIREBASE_PROJECT_ID=your-project-id

To run:

go run .

In another terminal, start a streaming request:

curl -N -i -H "Accept: text/event-stream" \
  -d '{"data": 5}' \
  http://localhost:8088/countdown

Note the X-Genkit-Stream-Id header. To reconnect to the same stream:

curl -N -H "Accept: text/event-stream" \
  -H "X-Genkit-Stream-Id: <stream-id>" \
  -d '{"data": 5}' \
  http://localhost:8088/countdown
