Web Locks API

Web Locks API implementation for Node.js based on worker_threads, Atomics, SharedArrayBuffer, asynchronous functions, and queue.

See specification: wicg.github.io/web-locks/ and documentation: developer.mozilla.org/en-US/docs/Web/API/Lock

This implementation is a part of Metarhia technology stack, needed for the first pilot project of Node.js application server based on parallel programming and workload micro-isolation. Web Locks API is intended to be merged into Node.js in future.

Features

• Simplest parallel programming primitive to solve a problem of data races and race conditions.
• Node.js and worker_threads support.
• Different optimized implementations for certain cases: single-threaded asynchronous locks, multi-threaded locks with a single unifyed API.

Installation

$ npm install web-locks

Usage

await locks.request('Resource name', async lock => {
  // use named resource and release it after return
});
