async-listen

The server.listen in Node.js is based on an event emitter, meaning the event should be waited before interacting with the server.

async-listen is the missing interface for consuming server.listen as promise.

Install

$ npm install async-listen --save

Usage

const listen = require('async-listen')
const { createServer } = require('http')

const server = createServer((req, res) => {
  res.end('hello world!')
})

const url = await listen(server)

console.log(`Listening at ${url.toString()}`)

After passing server as first argument, the rest of parameters are the same than server.listen:

/* IPv6 with random port (default) */
await listen(server)

/* IPv6 with port */
await listen(server, 3001)

/* IPv4 with random port */
await listen(server, { host: '127.0.0.1', port: 0 })
