Chances are you are struggling with the node js dying whenever the server you are calling refuses to connect   Try this   process on  uncaughtException   function  err        console log err          This keeps your server running and also give you a place to attach the debugger and look for a deeper problem

Had a similar issue  it turned out the listening port printed was different from what it actually was  Typos in the request string or listening function might make the target server appear to not exist

You need to have a server running on port 8080 when you run the code above that simply returns the request back through the response   Copy the code below to a separate file  say  server js   and start this server using the node command  node server js   You can then separately run your code above  node app js  from a separate command line   var http   require  http     http createServer function request  response          The following code will print out the incoming request text     request pipe response       listen 8080   127 0 0 1     console log  Listening on port 8080

The Unhandled  error  event is referring not providing a function to the request to pass errors   Without this event the node process ends with the error instead of failing gracefully and providing actual feedback   You can set the event just before the request write line to catch any issues   request on  error   function err        console log err         More examples below   https   nodejs org api http html http http request options callback

You re trying to connect to localhost 8080     is any service running on your localhost and on this port  If not  the connection is refused which cause this error  I would suggest to check if there is anything running on localhost 8080 first

Run server js from a different command line and client js from a different command line

People run into this error when the Node js process is still running and they are attempting to start the server again  Try this   ps aux   grep node  This will print something along the lines of   user    7668  4 3  1 0  42060 10708 pts 1    Sl   20 36   0 00 node server user    7749  0 0  0 0   4384   832 pts 8    S    20 37   0 00 grep --color auto node   In this case  the process will be the one with the pid 7668  To kill it and restart the server  run kill -9 7668

Sometimes it may occur  if there is any database connection in your code but you did not start the database server yet   Im my case i have some piece of code to connect with mongodb  mongoose connect  mongodb   localhost 27017 demoDb     after i started the mongodb server with the command mongod this error is gone
