## What Removes the `@sentry/node-core` package and folds its functionality back into `@sentry/node`. - Moves all node-core source into `@sentry/node`; the composite HTTP and node-fetch integrations become the canonical implementations. - Drops light mode and the optional OTel peer-dependency model. `@sentry/node` keeps only the OpenTelemetry dependencies it actually uses (`@opentelemetry/core` promoted to a direct dependency; `exporter-trace-otlp-http` dropped). - Migrates consumers (`effect`, `aws-serverless`, `bun`, `google-cloud-serverless`, `nuxt`) off `@sentry/node-core`. - Merges the node-core unit and integration tests that add coverage into `@sentry/node` and `node-integration-tests`; discards the redundant ones. Removes the `node-core-integration-tests` package and the node-core e2e apps. - Removes `@sentry/node-core` from workspaces, `.craft.yml`, `.size-limit.js`, CODEOWNERS, and CI. The public API surface of `@sentry/node` is unchanged. ### `@sentry/effect` `@sentry/effect` server now runs on full `@sentry/node` (previously `@sentry/node-core/light`) and disables node's default integrations, since it provides its own tracing, logging and error capture. Its server transaction e2e tests are marked `test.fixme`: light mode set an AsyncLocalStorage async context strategy that matched Effect's fiber model, whereas full node installs the OpenTelemetry context strategy, so the Effect tracer's spans are no longer emitted as transactions. Adapting Effect's server tracing to the full-node context model is follow-up work. ## Why `@sentry/node-core` was split out to offer the Node client without bundled OpenTelemetry instrumentation and with widened OTel peer ranges. The story around node without OpenTelemetry will change in v11 and we will no longer need this distinctive SDKs. The so-called light mode will be achievable with our regular node SDK in follow up PRs. <hr> For reviewers: 1. Move `@sentry/node-core` source into `@sentry/node`: [db7ec22](db7ec22) 2. Migrate consumer SDKs off `@sentry/node-core`: [cd41021](cd41021) 3. Merge node-core tests into `@sentry/node` and `node-integration-tests`: [17665c0](17665c0) 4. Remove `@sentry/node-core` package and its test/CI infrastructure: [226cdfc](226cdfc) Closes #21469 --------- Co-authored-by: Claude Opus 4.8 <noreply@anthropic.com>
