Tiny Mutex

Lightweight and simple mutexes.

Features

• Zero dependencies. Small bundle size.
• Written in TypeScript.
• Simple to use. Modeled after Golang's sync.Mutex
• Modern ESModules support.
• Thread-safe. Works perfectly with multithreading libraries like Nanolith.

Usage

It's dead simple. There are only three functions to know.

import { newMutex, lock, unlock } from 'tiny-mutex'

// Create a mutex
const mutex = newMutex();

async function doWorkflow(shared: Uint8Array) {
    // Wait until the mutex is unlocked, then lock it.
    await lock(mutex);

    // Modify a resource normally without worrying about
    // other threads modifying it at the same time.
    shared.set([1, 2, 3])

    // Unlock the mutex once finished with modifying the
    // resource, unblocking other agents.
    unlock(mutex);
}
