JavaScript SDK 7.78.0 Bundle Size Decrease

AUTHOR: Sentry

As always we are very sensitive to bundle size conerns of our users. The latest SDK version 7.78.0 caps off a series of bundle size improvements we made to Session Replay, leading to a 20 KB (~40% of Replay, ~25% of the full SDK) reduction.

Still while decreasing bundle we have shipped some new features:

  • Adds a new beforeErrorSampling() config callback to Replay

  • Adds improvements to our Astro SDK

  • Improves Replay performance by moving expensive truncation tasks out of the SDK

  • Improves our support for Next.js App Router

Check our changelog to see the full details of this release.
