Following the recent announcement of their Rust SDK, Pydantic Logfire has launched its official JavaScript/TypeScript SDK, designed to enhance platform monitoring and troubleshooting. While not yet fully featured compared to its Python counterpart, the SDK aims to achieve feature parity promptly, prioritizing user-needed capabilities. It offers first-class support for JavaScript with TypeScript and aligns closely with the Python SDK API. Key integrations include the @pydantic/logfire-cf-workers package for Cloudflare workers and compatibility with Vercel's observability platform, alongside easy setup for Vanilla Node.js/Express backends. Built on existing @opentelemetry NPM packages, it seamlessly integrates with current instrumentations, and user feedback is encouraged for further improvements.
