@sentry/react 10.49.0

on Node.js NPM

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.
