node js - request - How to emitter setMaxListeners

Question

When I do a GET on a certain URI using the node js  request  module   var options    uri  aURI   headers headerData   request get options  function  error  response  body        The error message is    Error  Exceeded maxRedirects  Probably stuck in a redirect loop     and there is also the following message     node  warning  possible EventEmitter memory leak detected  11 listeners added  Use emitter setMaxListeners   to increase limit     How do I setMaxListeners

Although adding something to nodejs module is possible, it seems to be not the best way (if you try to run your code on other computer, the program will crash with the same error, obviously).

I would rather set max listeners number in your own code:

var options = {uri:headingUri, headers:headerData, maxRedirects:100};
request.setMaxListeners(0);
request.get(options, function (error, response, body) {
}

I strongly advice NOT to use the code   process setMaxListeners 0     The warning is not there without reason  Most of the time  it is because there is an error hidden in your code  Removing the limit removes the warning  but not its cause  and prevents you from being warned of a source of resource leakage   If you hit the limit for a legitimate reason  put a reasonable value in the function  the default is 10    Also  to change the default  it is not necessary to mess with the EventEmitter prototype  you can set the value of defaultMaxListeners attribute like so   require  events   EventEmitter defaultMaxListeners   15

This is how I solved the problem   In main js of the  request  module I added one line   Request prototype request   function        var self   this   self setMaxListeners 0      Added line   This defines unlimited listeners http   nodejs org docs v0 4 7 api events html emitter setMaxListeners  In my code I set the  maxRedirects  value explicitly   var options    uri headingUri  headers headerData  maxRedirects 100
