Node.js unhandled 'error' event

Question

I have written a simple code and save it in file try.js .

var http = require('http'); var makeRequest = function(message) {   var options = {     host: 'localhost', port: 8080, path: '/', method: 'POST'   }   var request = http.request(options, function(response){     response.on('data', function(data){       console.log(data);     });   });    request.write(message);   request.end(); } makeRequest("Here's looking at you, kid."); 

When I run it through terminal it give an error

throw er; // Unhandled 'error' event, Error: connect ECONNREFUSED at errnoException (net.js:884:11) at Object.afterConnect [as oncomplete] (net.js:875:19)error' event 

Answer 1

For me, the problem was another instance was running. Search for other node instance running and kill it. It should resume properly after.

Answer 2

This is happening because nothing is listening on localhost:8080. Here are the examples how to handle request errors How to catch http client request exceptions in node.js
