Pydantic Logfire JavaScript SDK Announcement

Following our Rust SDK announcement from last week, We are announcing our official Logfire JavaScript/TypeScript SDK. We've been using parts of the SDK internally to monitor and troubleshoot our own platform for a while now (yes, we ourselves are happy users of Logfire!)

This is an initial release, so not all the options in our Python SDK are yet supported, however we're keen to reach feature parity and will prioritize the capabilities you need.

In short:

• First-class SDK for JavaScript, with TypeScript support. The SDK conforms to the Python SDK API as much as possible.
• @pydantic/logfire-cf-workers package for streamlining cloudflare workers instrumentation (example).

• Compatibility with Vercel's observability platform (example)

• Convenient setup for Vanilla Node.js/Express backend (example).
• Built on top of the existing @opentelemetry NPM packages, works out of the box with your existing instrumentations.

Please let us know what you think.
