React (coming soon)
Overview

React

⚠️

Not available yet. TracePath does not publish a React package. There is nothing to install, and the @tracepath scope on npm belongs to an unrelated third party — do not run an install command against it. This page describes the planned integration. Email [email protected] to hear when it ships.

The planned React package will wrap the browser SDK in the idioms a React app expects: one provider at the root of the tree, a hook for capturing inside components, and a declarative way to keep user context attached to every event.

What it will give you

PieceRole
ProviderInitializes the SDK once, and doubles as an error boundary for the whole tree
HooksCapture exceptions and messages from event handlers and async code
Error boundaryOpt-in component for replacing a crashed subtree with a custom fallback

Render-time exceptions thrown anywhere below the provider will be captured and then re-thrown, so the app behaves exactly as it would without TracePath installed. Session recording will be on by default, shipping the last ~30 s of DOM events with each captured exception.

One React-specific wrinkle worth knowing in advance: StrictMode double-invokes constructors in development, which creates two SDK clients and reports every uncaught error twice. Production builds are unaffected. See A note on StrictMode.

What to do today

If your React app has a server half — Next.js, Remix, or any Node backend — instrument it now with OpenTelemetry. That half is fully supported:

The browser half and the server half are two separate TracePath projects with two separate tokens either way; see Project Structure for why.

If it is a pure client-side app, synthetic monitors can watch it from the outside today with no code in the page at all.

Distributed tracing

The backend side of frontend-to-backend correlation is already implemented and is worth adding now: your server reads a tracepath-trace-id header and puts it on its span. See Distributed Tracing for the middleware, which is a few lines and runs today.
