Node.js: Crypto Correctness Sweep, Faster Web Streams, VFS Maturity
Web Crypto dominates with FIPS-aware availability and spec fixes headed for backport, while web streams get back-to-back performance trims and the virtual file system gains recursive listings and layered mounts.

Good morning, it's Wednesday, September 23rd, 2026, and this is your Node.js briefing.
The lead signal is correctness at the platform edge: a coordinated audit of Web Crypto and Web IDL, alongside steady speedups to web streams and real progress on the virtual file system.
First, crypto. Pull request 66-160, now merged, makes algorithm availability follow the current FIPS state instead of a cached value, refreshing registration on changes and tightening parameter checks. Around it, pull request 66-217 fixes raw key export to throw invalid access instead of not supported when the key…
Second, web streams performance. Pull request 66-154, round 18 and merged, replaces rebuilt read-request objects with a shared class, skips pull bookkeeping for push-only sources, and removes extra promises on tee and byte-reader paths. Pull request 66-230, round 19, keeps shared idle write markers in fast mode so…
Third, virtual files are growing up. Pull request 66-127 adds recursive directory listing to the zip provider, pull request 65-829 rejects creating entries under non-directory parents, and pull request 66-235 proposes a composable provider for layered mounts with copy-up writes.
