    on-net-listen

    Observe when something in your node app starts listening on a TCP port.

    npm install on-net-listen
    

    build status

    Uses async_hooks behind the scenes and requires Node >=9

    Usage

    var onnetlisten = require('on-net-listen')
     
    onnetlisten(function (addr) {
      // addr is the same object as server.address()
      // for the port do addr.port
      console.log('Someone started listening:', addr)
    })
     
    var http = require('http')
     
    var server = http.createServer(function () {
      // ...
    })
     
    server.listen(0) // will trigger the above listener

    API

    var emitter = onnetlisten(onlistening)

    Start listening for when TCP servers start listening.

    The returned event emitter emits listening when that happens with the address object for the tcp server that started listening.

    To stop the listener do emitter.destroy()
