Get started

Use @anvia/langfuse when Anvia traces, evaluation scores, datasets, experiments, and managed prompts should integrate with a Langfuse project.

pnpm add @anvia/core @anvia/langfuse

LANGFUSE_PUBLIC_KEY=pk_...
LANGFUSE_SECRET_KEY=sk_...
LANGFUSE_BASE_URL=https://cloud.langfuse.com
LANGFUSE_TRACING_ENVIRONMENT=production
LANGFUSE_RELEASE=support-api@1.0.0
LANGFUSE_SERVICE_NAME=support-api

import { Agent } from '@anvia/core'
import { LangfuseClient } from '@anvia/langfuse'

const langfuse = new LangfuseClient({
  release: process.env.APP_RELEASE,
})
const tracing = langfuse.observer({ captureMode: 'safe' })

const agent = new Agent({
  id: 'support',
  model: model,
  observability: { observers: { tracing } },
})

Explicit options override environment variables. The base URL defaults to Langfuse Cloud and request timeout defaults to 30 seconds.

Call langfuse.flush() in short-lived work and langfuse.close() when the integration will no longer be used.
