listen.js

listen.js

Listen.js is a function that helps abstract listening functionality for your express-based apps. There's a good chance it'll work for other stuff as well, but this has not been tested.

It supports listening on either a port or a unix socket and handles left behind socket files and such by checking if they're still in use. If a socket file is still in use, the process will exit. If not, it'll delete the socket file and listen.

$ npm install --save listen.js

Usage

var app = require('express')(),
  listen = require('listen.js')

listen(app, 3000);
// or
listen(app, '/var/run/myapp.sock');
