node-semaphore

A small semaphore in vanilla JS, useful as a lock pool for something like rate limiting

Install

npm install node-semaphore

Usage

Using Sempahore is really easy, just acquire() when you want access to a lock and release() when you're done.

var Semaphore = require("node-semaphore");
var pool = Semaphore(5);
for (int i = 0; i < 250; i++) {
    pool.acquire(function() {
        console.log("Running...");
        pool.release();
    });
}

This code will run through 250 iterations, 5 clients at a time.
