Sentry JavaScript

Important Changes

• feat(browser): Add View Hierarchy integration (#14981)

  A new viewHierarchyIntegration captures the DOM structure when an error occurs, providing a snapshot of the page state for debugging. Enable it in your Sentry configuration:

  import * as Sentry from '@sentry/browser';
  
  Sentry.init({
    dsn: '__DSN__',
    integrations: [Sentry.viewHierarchyIntegration()],
  });

• feat(cloudflare): Split alarms into multiple traces and link them (#19373)

  Durable Object alarms now create separate traces for each alarm invocation, with proper linking between related alarms for better observability.

• feat(cloudflare): Enable RPC trace propagation with enableRpcTracePropagation (#19991, #20345)

  A new enableRpcTracePropagation option enables automatic trace propagation for Cloudflare RPC calls via .fetch(), ensuring distributed traces flow correctly across service bindings.

• feat(core): Add enableTruncation option to AI integrations (#20167, #20181, #20182, #20183, #20184)

  All AI integrations (OpenAI, Anthropic, Google GenAI, LangChain, LangGraph) now support an enableTruncation option to control whether large AI inputs/outputs are truncated.

• feat(opentelemetry): Vendor AsyncLocalStorageContextManager (#20243)

  The OpenTelemetry context manager is now vendored internally, reducing external dependencies and ensuring consistent behavior across environments.

Important Changes

• feat(aws-serverless): Ship Lambda extension in npm package for container image Lambdas (#20133)

  The Sentry Lambda extension is now included in the npm package, enabling container image-based Lambda functions to use it. Copy the extension files into your Docker image and set the tunnel option:

  RUN mkdir -p /opt/sentry-extension
  COPY node_modules/@sentry/aws-serverless/build/lambda-extension/sentry-extension /opt/extensions/sentry-extension
  COPY node_modules/@sentry/aws-serverless/build/lambda-extension/index.mjs /opt/sentry-extension/index.mjs
  RUN chmod +x /opt/extensions/sentry-extension /opt/sentry-extension/index.mjs
  

  Sentry.init({
    dsn: '__DSN__',
    tunnel: 'http://localhost:9000/envelope',
  });

  This works with any Sentry SDK (@sentry/aws-serverless, @sentry/sveltekit, @sentry/node, etc.).

• feat(cloudflare): Support basic WorkerEntrypoint (#19884)

  withSentry now supports instrumenting classes extending Cloudflare's WorkerEntrypoint. This instruments fetch, scheduled, queue, and tail handlers.

  import * as Sentry from '@sentry/cloudflare';
  import { WorkerEntrypoint } from 'cloudflare:workers';
  
  class MyWorker extends WorkerEntrypoint {
    async fetch(request: Request): Promise<Response> {
      return new Response('Hello World!');
    }
  }
  
  export default Sentry.withSentry(env => ({ dsn: env.SENTRY_DSN, tracesSampleRate: 1.0 }), MyWorker);

• ref(core): Unify .do* span ops to gen_ai.generate_content (#20074)

  All Vercel AI do* spans (ai.generateText.doGenerate, ai.streamText.doStream, ai.generateObject.doGenerate, ai.streamObject.doStream) now use a single unified span op gen_ai.generate_content instead of separate ops like gen_ai.generate_text, gen_ai.stream_text, gen_ai.generate_object, and gen_ai.stream_object.

• ref(core): Remove provider-specific AI span attributes in favor of gen_ai attributes in sentry conventions (#20011)

  The following provider-specific span attributes have been removed from the OpenAI and Anthropic AI integrations. Use the standardized gen_ai.* equivalents instead:

  Removed attribute	Replacement
  openai.response.id	gen_ai.response.id
  openai.response.model	gen_ai.response.model
  openai.usage.prompt_tokens	gen_ai.usage.input_tokens
  openai.usage.completion_tokens	gen_ai.usage.output_tokens
  openai.response.timestamp	(removed, no replacement)
  anthropic.response.timestamp	(removed, no replacement)

  If you reference these attributes in hooks (e.g. beforeSendTransaction), update them to the gen_ai.* equivalents.

• feat(core): Support embeddings in LangChain (#20017)

  Adds instrumentation for LangChain embeddings (embedQuery, embedDocuments), creating gen_ai.embeddings spans. In Node.js, embedding classes from @langchain/openai, @langchain/google-genai, @langchain/mistralai, and @langchain/google-vertexai are auto-instrumented. For other runtimes, use the new instrumentLangChainEmbeddings API:

  import * as Sentry from '@sentry/cloudflare';
  import { OpenAIEmbeddings } from '@langchain/openai';
  
  const embeddings = Sentry.instrumentLangChainEmbeddings(new OpenAIEmbeddings({ model: 'text-embedding-3-small' }));
  
  await embeddings.embedQuery('Hello world');

Important Changes

• feat(node-core): Add OTLP integration for node-core/light (#19729)

  Added otlpIntegration at @sentry/node-core/light/otlp for users who manage their own OpenTelemetry setup and want to send trace data to Sentry without adopting the full @sentry/node SDK.

  import { NodeTracerProvider } from '@opentelemetry/sdk-trace-node';
  import * as Sentry from '@sentry/node-core/light';
  import { otlpIntegration } from '@sentry/node-core/light/otlp';
  
  const provider = new NodeTracerProvider();
  provider.register();
  
  Sentry.init({
    dsn: '__DSN__',
    integrations: [
      otlpIntegration({
        // Export OTel spans to Sentry via OTLP (default: true)
        setupOtlpTracesExporter: true,
      }),
    ],
  });

  The integration links Sentry errors to OTel traces and exports spans to Sentry via OTLP.

• feat(node, bun): Add runtime metrics integrations for Node.js and Bun (#19923, #19979)

  New nodeRuntimeMetricsIntegration and bunRuntimeMetricsIntegration automatically collect runtime health metrics and send them to Sentry on a configurable interval (default: 30s). Collected metrics include memory (RSS, heap used/total), CPU utilization, event loop utilization, and process uptime. Node additionally collects event loop delay percentiles (p50, p99). Extra metrics like CPU time and external memory are available as opt-in.

  // Node.js
  import * as Sentry from '@sentry/node';
  
  Sentry.init({
    dsn: '...',
    integrations: [Sentry.nodeRuntimeMetricsIntegration()],
  });
  
  // Bun
  import * as Sentry from '@sentry/bun';
  
  Sentry.init({
    dsn: '...',
    integrations: [Sentry.bunRuntimeMetricsIntegration()],
  });

• feat(core): Support embedding APIs in google-genai (#19797)

  Adds instrumentation for the Google GenAI embedContent API, creating gen_ai.embeddings spans.

• feat(browser): Add elementTimingIntegration for tracking element render and load times (#19869)

  The new elementTimingIntegration captures Element Timing API data as Sentry metrics. It emits element_timing.render_time and element_timing.load_time distribution metrics for elements annotated with the elementtiming HTML attribute.

  import * as Sentry from '@sentry/browser';
  
  Sentry.init({
    dsn: '__DSN__',
    integrations: [Sentry.browserTracingIntegration(), Sentry.elementTimingIntegration()],
  });

Important Changes

• feat(elysia): @sentry/elysia - Alpha Release (#19509)

  New Sentry SDK for the Elysia web framework, supporting both Bun and Node.js runtimes.

  Note: This is an alpha release. Please report any issues or feedback on GitHub.

  Features

  • Automatic error capturing — 5xx errors captured via global onError hook; 3xx/4xx ignored by default. Customizable with shouldHandleError.
  • Automatic tracing — Lifecycle spans for every Elysia phase (Request, Parse, Transform, BeforeHandle, Handle, AfterHandle, MapResponse, AfterResponse, Error) with parameterized route names (e.g. GET /users/:id).
  • Distributed tracing — sentry-trace and baggage headers propagated automatically on incoming/outgoing requests.

  Usage

  import * as Sentry from '@sentry/elysia';
  import { Elysia } from 'elysia';
  
  Sentry.init({ dsn: '__DSN__', tracesSampleRate: 1.0 });
  
  const app = Sentry.withElysia(new Elysia());
  app.get('/', () => 'Hello World');
  app.listen(3000);

Important Changes

• feat(effect): Add @sentry/effect SDK (Alpha) (#19644)

  This release introduces @sentry/effect, a new SDK for Effect.ts applications. The SDK provides Sentry integration via composable Effect layers for both Node.js and browser environments.

  Compose the effectLayer with optional tracing, logging, and metrics layers to instrument your Effect application:

  import * as Sentry from '@sentry/effect';
  import * as Layer from 'effect/Layer';
  import * as Logger from 'effect/Logger';
  
  const SentryLive = Layer.mergeAll(
    Sentry.effectLayer({ dsn: '__DSN__', tracesSampleRate: 1.0, enableLogs: true }),
    Layer.setTracer(Sentry.SentryEffectTracer),
    Logger.replace(Logger.defaultLogger, Sentry.SentryEffectLogger),
    Sentry.SentryEffectMetricsLayer,
  );

  Alpha features are still in progress, may have bugs and might include breaking changes. Please reach out on GitHub if you have any feedback or concerns.

• feat(astro): Add Astro 6 support (#19745)

  This release enables full support for Astro v6 by adjusting our Astro SDK's middleware to some Astro-internal changes. We cannot yet guarantee full support for server-islands, due to a bug in Astro v6 but we'll follow up on this once the bug is fixed.

• feat(hono): Add basic instrumentation for Node runtime (#19817)

  Adds a new package @sentry/hono/node (alpha) with basic instrumentation for Hono applications running in Node.js. The Hono middleware for Cloudflare (@sentry/hono/cloudflare - alpha) comes with fixes, and it's now possible to access the Cloudflare Worker Bindings (env) from the options' callback.

  Start using the new Hono middlewares by installing @sentry/hono and importing the respective middleware for your runtime. More instructions can be found in the Hono readme.

  Alpha features are still in progress, may have bugs and might include breaking changes. Please reach out on GitHub if you have any feedback or concerns.

• feat(nestjs): Instrument @nestjs/bullmq @Processor decorator (#19759)

  Automatically capture exceptions and create transactions for BullMQ queue processors in NestJS applications.

  When using the @Processor decorator from @nestjs/bullmq, the SDK now automatically wraps the process() method to create queue.process transactions with proper isolation scopes, preventing breadcrumb and scope leakage between jobs and HTTP requests. Errors thrown in processors are captured with the auto.queue.nestjs.bullmq mechanism type.

  Requires @nestjs/bullmq v10.0.0 or later.

• feat(nestjs): Instrument @nestjs/schedule decorators (#19735)

  Automatically capture exceptions thrown in @Cron, @Interval, and @Timeout decorated methods.

  Previously, exceptions in @Cron methods were only captured if you used the SentryCron decorator. Now they are captured automatically. The exception mechanism type changed from auto.cron.nestjs.async to auto.function.nestjs.cron. If you have Sentry queries or alerts that filter on the old mechanism type, update them accordingly.

• feat(node): Expose headersToSpanAttributes option on nativeNodeFetchIntegration() (#19770)

  Response headers like http.response.header.content-length were previously captured automatically on outgoing fetch spans but are now opt-in since @opentelemetry/instrumentation-undici@0.22.0. You can now configure which headers to capture via the headersToSpanAttributes option.

  Sentry.init({
    integrations: [
      Sentry.nativeNodeFetchIntegration({
        headersToSpanAttributes: {
          requestHeaders: ['x-custom-header'],
          responseHeaders: ['content-length', 'content-type'],
        },
      }),
    ],
  });

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)

Important Changes

• feat(core,cloudflare,deno): Add instrumentPostgresJsSql instrumentation (#19566)

  Added a new instrumentation helper for the postgres (postgres.js) library, designed for SDKs that are not based on OpenTelemetry (e.g. Cloudflare, Deno). This wraps a postgres.js sql tagged template instance so that all queries automatically create Sentry spans.

  import postgres from 'postgres';
  import * as Sentry from '@sentry/cloudflare'; // or '@sentry/deno'
  
  export default Sentry.withSentry(env => ({ dsn: '__DSN__' }), {
    async fetch(request, env, ctx) {
      const sql = Sentry.instrumentPostgresJsSql(postgres(env.DATABASE_URL));
  
      // All queries now create Sentry spans
      const users = await sql`SELECT * FROM users WHERE id = ${userId}`;
      return Response.json(users);
    },
  });

  The instrumentation is available in @sentry/core, @sentry/cloudflare, and @sentry/deno.

• feat(nextjs): Add Turbopack support for thirdPartyErrorFilterIntegration (#19542)

  We added experimental support for the thirdPartyErrorFilterIntegration with Turbopack 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: {
      turbopackApplicationKey: 'my-app-key',
    },
  });

  Then configure the integration in your client instrumentation file with a matching key:

  // instrumentation-client.ts
  import * as Sentry from '@sentry/nextjs';
  
  Sentry.init({
    integrations: [
      Sentry.thirdPartyErrorFilterIntegration({
        filterKeys: ['my-app-key'],
        behaviour: 'apply-tag-if-exclusively-contains-third-party-frames',
      }),
    ],
  });

Important Changes

• feat(tanstackstart-react): Add global sentry exception middlewares (#19330)

  The sentryGlobalRequestMiddleware and sentryGlobalFunctionMiddleware global middlewares capture unhandled exceptions thrown in TanStack Start API routes and server functions. Add them as the first entries in the requestMiddleware and functionMiddleware arrays of createStart():

  import { createStart } from '@tanstack/react-start/server';
  import { sentryGlobalRequestMiddleware, sentryGlobalFunctionMiddleware } from '@sentry/tanstackstart-react';
  
  export default createStart({
    requestMiddleware: [sentryGlobalRequestMiddleware, myRequestMiddleware],
    functionMiddleware: [sentryGlobalFunctionMiddleware, myFunctionMiddleware],
  });

• feat(tanstackstart-react)!: Export Vite plugin from @sentry/tanstackstart-react/vite subpath (#19182)

  The sentryTanstackStart Vite plugin is now exported from a dedicated subpath. Update your import:

  - import { sentryTanstackStart } from '@sentry/tanstackstart-react';
  + import { sentryTanstackStart } from '@sentry/tanstackstart-react/vite';
  

• fix(node-core): Reduce bundle size by removing apm-js-collab and requiring pino >= 9.10 (#18631)

  In order to keep receiving pino logs, you need to update your pino version to >= 9.10, the reason for the support bump is to reduce the bundle size of the node-core SDK in frameworks that cannot tree-shake the apm-js-collab dependency.

• fix(browser): Ensure user id is consistently added to sessions (#19341)

  Previously, the SDK inconsistently set the user id on sessions, meaning sessions were often lacking proper coupling to the user set for example via Sentry.setUser(). Additionally, the SDK incorrectly skipped starting a new session for the first soft navigation after the pageload. This patch fixes these issues. As a result, metrics around sessions, like "Crash Free Sessions" or "Crash Free Users" might change. This could also trigger alerts, depending on your set thresholds and conditions. We apologize for any inconvenience caused!

  While we're at it, if you're using Sentry in a Single Page App or meta framework, you might want to give the new 'page' session lifecycle a try! This new mode no longer creates a session per soft navigation but continues the initial session until the next hard page refresh. Check out the docs to learn more!

• ref!(gatsby): Drop Gatsby v2 support (#19467)

Important Changes

• feat(tanstackstart-react): Auto-instrument server function middleware (#19001)

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

• feat(nextjs): New experimental automatic vercel cron monitoring (#19192)

  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,
    },
  });

• feat(node-core): Add node-core/light (#18502)

  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__',
  });

Bundle size 📦

This preview release includes updates to our Span Streaming PoC implementation. Use at your own risk.

New:

• Browser: SDKs now also use a span buffer, flushing periodically, on span amount limit and on segment span end
• Browser: It's now enough to only register spanStreamingIntegration in Sentry.init.() to opt into span streaming
• Browser: sentry.replay_id attribute is attached to spans started during an active replay
• Browser: sentry.profiler_id attribute is attached to spans started while the continuous profiler is running
• Browser: Web vital spans are sent as v2 spans
• Browser: spanStreamingIntegration is now exported from CDN bundles supporting tracing

Known issues:

• Missing data from various integrations and framework SDKs
• ignoreSpans is not yet applied

Untested:

• Meta frameworks or framework SDKs building on top of @sentry/browser or @sentry/node. Likely, data is missing, noisy spans are not filtered, etc.

Usage (At your own risk)

Browser

Sentry.init({
  dsn: '...',
  integrations: [
    Sentry.browserTracingIntegration(),
    Sentry.spanStreamingIntegration(),
  ]
})

Server (Node)

Sentry.init({
  dsn: '...',
  traceLifecycle: 'stream',
})

  import * as Sentry from '@sentry/node';
  
  // Set conversation ID for all subsequent spans
  Sentry.setConversationId('conv_abc123');
  
  // All AI spans will now include the gen_ai.conversation.id attribute
  await openai.chat.completions.create({...});

  This is particularly useful for tracking multiple AI API calls that are part of the same conversation, allowing you to analyze entire conversation flows in Sentry. The conversation ID is stored on the isolation scope and automatically applied to spans via the new conversationIdIntegration.

• feat(tanstackstart-react): Auto-instrument global middleware in sentryTanstackStart Vite plugin (#18844)

  The sentryTanstackStart Vite plugin now automatically instruments requestMiddleware and functionMiddleware arrays in createStart(). This captures performance data without requiring manual wrapping.

  Auto-instrumentation is enabled by default. To disable it:

  // vite.config.ts
  sentryTanstackStart({
    authToken: process.env.SENTRY_AUTH_TOKEN,
    org: 'your-org',
    project: 'your-project',
    autoInstrumentMiddleware: false,
  });

Important Changes

• feat(core): Add option to enhance the fetch error message (#18466)

  You can now enable enhanced fetch error messages by setting the enhancedFetchErrorMessage option. When enabled, the SDK will include additional context in fetch error messages to help with debugging.

  A new routeManifestInjection option allows you to exclude sensitive routes from being injected into the client bundle.

• feat(tanstackstart-react): Add wrapMiddlewaresWithSentry for manual middleware instrumentation (#18680)

  You can now wrap your middlewares using wrapMiddlewaresWithSentry, allowing you to trace middleware execution in your TanStack Start application.

  import { createMiddleware } from '@tanstack/react-start';
  import { wrapMiddlewaresWithSentry } from '@sentry/tanstackstart-react';
  
  const loggingMiddleware = createMiddleware({ type: 'function' }).server(async ({ next }) => {
    console.log('Request started');
    return next();
  });
  
  export const [wrappedLoggingMiddleware] = wrapMiddlewaresWithSentry({ loggingMiddleware });

Important Changes

• feat(core): Apply scope attributes to metrics (#18738)

  You can now set attributes on the SDK's scopes which will be applied to all metrics as long as the respective scopes are active. For the time being, only string, number and boolean attribute values are supported.

  Sentry.getGlobalScope().setAttributes({ is_admin: true, auth_provider: 'google' });
  
  Sentry.withScope(scope => {
    scope.setAttribute('step', 'authentication');
  
    // scope attributes `is_admin`, `auth_provider` and `step` are added
    Sentry.metrics.count('clicks', 1, { attributes: { activeSince: 100 } });
    Sentry.metrics.gauge('timeSinceRefresh', 4, { unit: 'hour' });
  });
  
  // scope attributes `is_admin` and `auth_provider` are added
  Sentry.metrics.count('response_time', 283.33, { unit: 'millisecond' });

• feat(tracing): Add Vercel AI SDK v6 support (#18741)

  The Sentry SDK now supports the Vercel AI SDK v6. Tracing and error monitoring will work automatically with the new version.

• feat(wasm): Add applicationKey option for third-party error filtering (#18762)

  Adds support for applying an application key to WASM stack frames that can be then used in the thirdPartyErrorFilterIntegration for detection of first-party code.

  Usage:

  Sentry.init({
    integrations: [
      // Integration order matters: wasmIntegration needs to be before thirdPartyErrorFilterIntegration
      wasmIntegration({ applicationKey: 'your-custom-application-key' }), ←───┐
      thirdPartyErrorFilterIntegration({                                      │
        behaviour: 'drop-error-if-exclusively-contains-third-party-frames',   ├─ matching keys
        filterKeys: ['your-custom-application-key'] ←─────────────────────────┘
      }),
    ],
  });
