Node.js http.createServer how to get error

Question

I am new to node.js and am trying to experiment with basic stuff.

My code is this

var http = require(\"http\");
http.createServer(function(request,          


        

Answer 1

You can use

process.on('uncaughtException', function(e){
    console.log(e);
});

To handle uncaught exceptions. Any unhandled exception from the web server could be caught like this.

Answer 2

You can do this by handling the error event on the server you are creating. First, get the result of .createServer().

var server = http.createServer(function(request, response) {

Then, you can easily handle errors:

server.on('error', function (e) {
  // Handle your error here
  console.log(e);
});

Answer 3

The error is emitted in the listen() method. The API documentation includes an example just for your situtation.

Answer 4

Print stacktrace of uncaught exceptions using following code.

process.on('uncaughtException', function( err ) {
            console.error(err.stack);
 });
