Async concurrency primitives for cooperating tasks in one JavaScript runtime.

Installation

pnpm add @richie696/react-framework-concurrency

Public capabilities

• AsyncMutex and SingleFlight for serialization and shared in-flight work.
• ReentrantLock with explicit LockOwner tokens, fairness, cancellation and Condition support.
• ReadWriteLock for shared readers and an exclusive reentrant writer.
• StampedLock for optimistic-read validation.
• Condition, LockError, LockErrorCode and createLockOwner.

Example

import { ReentrantLock, createLockOwner } from '@richie696/react-framework-concurrency';

const lock = new ReentrantLock();
const owner = createLockOwner('cache-update');

await lock.runExclusiveWith(owner, async () => {
  // One cooperating async task at a time.
});

Locks are not cross-tab, cross-worker or cross-process synchronization. Always release explicit lock holds, preferably through runExclusive, runRead or runWrite.
