10.39.0-alpha.0

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',
})
