NODE STREAM ABORT HANDLING FIXED, DOC-KIT TOOLCHAIN BUMPED ACROSS THE BOARD

By RepoJournal · Filed · About Node.js

Stream consumers now reject immediately when abort signals fire instead of hanging on pending reads, closing a critical gap in Node's async iterator cleanup.

The stream/iter module got two critical fixes overnight [1] [2]. First, `bytes()`, `text()`, `arrayBuffer()`, and `array()` now reject promptly when their abort signal fires while an async iterator read is pending - previously they'd hang if the source was stuck in a `next()` call. Second, `merge()` no longer hangs when abort fires during multi-source merge loops. Both changes reuse abort-aware iterator wrappers to ensure consistent signal handling across the API. On the tooling side, doc-kit pushed a sweep of dependency updates: shiki bumped to 4.3.0 [3], the compiling group (@swc/html-wasm and rolldown) refreshed [4], and six lint tools updated including ESLint to 10.6.0 [5]. ERR_REQUIRE_ASYNC_MODULE got improved diagnostics with non-enumerable requireStack properties [6], and workflows cleaned up by removing envinfo [7].
