nbufpool

Note: for experimental implementation based on FinalizationGroup API see this branch.

An unsafe Buffer pool for Node.js: a port of Buffer.allocUnsafe. See this issue to understand why and when it might be helpful.

Usage

Using this library as easy as the following two steps.

Step 1. Install it:

npm install --save nbufpool

Step 2. Write some code:

const Pool = require('nbufpool');
// create pool
const pool = new Pool(2048); // 2MB
// allocate buffers, where necessary
const buf = pool.allocUnsafe(128); // 128B
