Sentry
Sentry JavaScript
The JavaScript SDK expanded support for emerging frameworks and runtimes while deepening observability into application layers. New SDKs shipped for Elysia and Effect.ts, each bringing framework-specific instrumentation; @sentry/effect exposed Effect layers for composable error handling and tracing, while @sentry/elysia added automatic lifecycle span capture across request phases and parameterized route names. Existing frameworks gained smarter instrumentation—Remix now propagates traces via Server-Timing headers, Next.js added Turbopack support for React component annotations, and TanStack Start's Vite plugin began auto-instrumenting middleware and request handlers without manual wrapping. For backend environments, the Lambda extension moved into the npm package for container images, postgres.js queries gained automatic span wrapping, and a lightweight node-core/light variant emerged for teams managing their own OpenTelemetry setup. Browser-side error debugging improved with a View Hierarchy integration that captures DOM snapshots on error, while conversation tracking arrived via setConversationId() to link multi-turn AI API calls within a single trace.
The SDK expanded framework coverage and OpenTelemetry support throughout March. New SDKs shipped for Elysia (with automatic error capturing and lifecycle tracing across request phases) and Effect.ts (via composable layers), while the Node.js core gained an OTLP integration for users managing their own OpenTelemetry setup. Existing frameworks saw targeted improvements: Next.js added experimental Turbopack support for React component annotation, Remix enabled trace propagation via Server-Timing headers, and postgres.js instrumentation rolled out across Cloudflare and Deno SDKs.
Span streaming infrastructure drove the month forward. The team shipped automatic middleware instrumentation for TanStack Start that captures performance data without manual wrapping, added global exception middlewares to catch unhandled errors in API routes and server functions, and launched experimental Vercel Cron monitoring for Next.js. Browser SDKs now buffer and periodically flush spans while attaching replay and profiler IDs to trace context.
