@sentry/node

Important Changes

• tanstackstart-react: Auto-instrument server function middleware

  The sentryTanstackStart Vite plugin now automatically instruments middleware in createServerFn().middleware([...]) calls. This captures performance data without requiring manual wrapping with wrapMiddlewaresWithSentry().

• nextjs: New experimental automatic vercel cron monitoring

  Setting _experimental.vercelCronMonitoring to true in your Sentry configuration will automatically create Sentry cron monitors for your Vercel Cron Jobs.

  Please note that this is an experimental unstable feature and subject to change.

  // next.config.ts
  export default withSentryConfig(nextConfig, {
    _experimental: {
      vercelCronMonitoring: true,
    },
  });

• node-core: Add node-core/light

  This release adds a new light-weight @sentry/node-core/light export to @sentry/node-core. The export acts as a light-weight SDK that does not depend on OpenTelemetry and emits no spans.

  Use this SDK when:

  • You only need error tracking, logs or metrics without tracing data (no spans)

  • You want to minimize bundle size and runtime overhead

  • You don't need spans emitted by OpenTelemetry instrumentation

  It supports error tracking and reporting, logs, metrics, automatic request isolation (requires Node.js 22+) and basic tracing via our Sentry.startSpan* APIs.

  Install the SDK by running

  npm install @sentry/node-core

  and add Sentry at the top of your application's entry file:

  import * as Sentry from '@sentry/node-core/light';
  
  Sentry.init({
    dsn: '__DSN__',
  });
