This package provides a wrapper for Langfuse. The wrapper serves to initialize Langfuse appropriately if the Langfuse server is running locally and otherwise to skip applying the Langfuse observe descorators.

Note: This Langfuse integration is experimental and we don't currently have integration tests for it.

Usage

Start your local Langfuse server

Run setup_langfuse.sh to start your local Langfuse server. It requires Docker.

Read more about local Langfuse deployments here.

Exchange and Goose integration

Import from langfuse_wrapper.langfuse_wrapper import observe_wrapper and use the observe_wrapper() decorator on functions you wish to enable tracing for. observe_wrapper functions the same way as Langfuse's observe decorator.

In Goose, initialization requires certain environment variables to be present:

LANGFUSE_PUBLIC_KEY: Your Langfuse public key
LANGFUSE_SECRET_KEY: Your Langfuse secret key
LANGFUSE_BASE_URL: The base URL of your Langfuse instance

By default your local deployment and Goose will use the values in env/.env.langfuse.local.
