Ensure Port

Makes sure you get an available port.

Installation

npm i ensure-port

yarn add ensure-port

Usage

import { Ports } from 'ensure-port';

const ports = new Ports({
  startPort: 8000,
  endPort: 9000,
});

const port = await ports.ensure(); // This would be a random port between 8000 and 9000 that is not used (validated again file-system and http server)

// When you finish - remove watcher
await ports.dispose();

How does it work?

It saves inside your node_modules a directory that contain all the ports that are in use. This is why it works in parallel.
