10.43.0 — Sentry JavaScript

Important Changes

feat(nextjs): Add Turbopack support for React component name annotation (#19604)

We added experimental support for React component name annotation in Turbopack builds. When enabled, JSX elements are annotated with data-sentry-component, data-sentry-element, and data-sentry-source-file attributes at build time. This enables searching Replays by component name, seeing component names in breadcrumbs, and performance monitoring — previously only available with webpack builds.

This feature requires Next.js 16+ and is currently behind an experimental flag:
```
// next.config.ts
import { withSentryConfig } from '@sentry/nextjs';

export default withSentryConfig(nextConfig, {
  _experimental: {
    turbopackReactComponentAnnotation: {
      enabled: true,
      ignoredComponents: ['Header', 'Footer'], // optional
    },
  },
});
```
feat(hono): Instrument middlewares app.use() (#19611)

Hono middleware registered via app.use() is now automatically instrumented, creating spans for each middleware invocation.
