server-starter

A simple tool for starting node servers on a port and optionally hostname or a unix socket.

This tool starts a server. If a unix socket is specified, and the file already exists, it is detected, tested to see if it is alive, and removed if it is indeed dead. It also allows setting a file mode and owner for the socket after creation.

Install

yarn add server-starter

npm install server-starter --save

Usage

server-starter works on any "server" that has a ".listen(..)" method that takes a first argument that is a port number or socket file and an optional second argument, which is only valid if a port number was specified as the first argument, that is the network device to listen on.

const ServerStarter = require('server-starter');

const server = new require('net').Server();

const socketOptions = {
  listen: 'path/to/socket',
  socketMode: 0770,
  socketOwner: {
    user: 1000,
    group: 1000,
  }
}
const ipOptions = {
  listen: 9001,
  hostname: '127.0.0.1',
}

const options = socketOptions || ipOptions;

ServerStarter(server, options, (err, info, extra) => {
  if (err) {
    console.log(err, info, extra);
  } else {
    console.log('Listening:', info);
  }
});

You can use strings for socketOwner user or group.
