Worker Kit

0.3.1

2026-10-21

Fixed: chunks is also notified in a hidden tab — a 50 ms timer replaces requestAnimationFrame, which does not fire in a background tab.
Changed (behaviour fix): after pool.terminate(), run() / call() / map() reject with WorkerError code: 'POOL_TERMINATED' instead of silently creating new workers; tasks waiting or running at that moment reject with the same error.
Added: pool.restart() re-opens a terminated pool.
Added: npm run test:browser — a Playwright run of the cancel-yield.html demo stand in Chromium, Firefox and WebKit.
Verified: with about 4 ms of work between ctx.yield() calls, a loop stops after at most 2 further yield() calls in 100 of 100 attempts in all three browsers; one yield() costs about 20 µs (Chromium, Firefox) and 0.3–0.4 ms (WebKit). The implementation is unchanged.
Docs: affinity rules, "how often to call yield()", terminate() of a single worker versus a pool; README, site and AI reference synchronised with the code.

Fixed: chunks of useWorker() / useSharedWorker() is now reactive.
Fixed: a worker pool recovers from a crashed worker — the dead slot is removed and the queue continues on new slots.
Added: cancelling queued pool tasks and hardCancelOnAbort (pool option, RunOptions, WorkerMapOptions).
Added: ctx.yield() and ctx.throwIfAborted() for cooperative cancellation in long loops.
Added: per-call onProgress / onChunk in run().
Added: concurrency: 'parallel' | 'latest' | 'serial', isSupersededError().
Added: defineWorkerOperations() and typed call(name, input).
Added: WorkerHandlerError with code / details / cause.
Added: unwrap: 'shallow' | 'deep' with a dev hint for reactive proxies.
Added: useWorkerComputed() options worker, immediate and refresh().
Added: pool idleTimeout and affinity / affinityMode.
