Nub 0.2.3

A localStorage compatibility fix, two compat-floor polyfill families, a prebuilt Nix flake, and a startup-path speedup.

A patch release: a localStorage compatibility fix, two compat-floor runtime polyfill families, a prebuilt Nix flake, and a startup-path speedup.

Runtime fixes

localStorage matches vanilla Node on the 22.4–24 web-storage band. When web storage is unconfigured, Nub previously left localStorage present-but-undefined; it is now absent, exactly as on plain Node. This fixes test setups (vitest with happy-dom) and isomorphic libraries that feature-detect via an in check on the global. sessionStorage is unaffected. (#170, closes #166)

Runtime polyfills

Two TC39 feature families are now polyfilled where the running Node lacks them natively, complementing Nub's existing down-leveling. (#174)

FeatureWhat changedAvailability
Uint8Array base64/hexThe base64 and hex conversion methods are polyfilledabsent on Node 24 and below, native 25+
Explicit Resource ManagementDisposableStack, AsyncDisposableStack, and SuppressedError are polyfilledabsent on Node 23 and below, native 24+

Distribution

A prebuilt-binary Nix flake ships: install via nix run github:nubjs/nub or nix profile install github:nubjs/nub. (#169, closes #167)

Performance

Redundant work was removed from the startup path. (#160)
