How do I disable console.log when I am not debugging? [duplicate]

Answer 1

One more way to disable console.log in production and keep it in development.

// overriding console.log in production
if(window.location.host.indexOf('localhost:9000') < 0) {
    console.log = function(){};
}

You can change your development settings like localhost and port.

Answer 2

// In Development:
var debugMode = true

// In Prod:
var debugMode = false

// This function logs console messages when debugMode is true .
function debugLog(logMessage) {
    if (debugMode) {
        console.log(logMessage);
    }
}

// Use the function instead of console.log
debugLog("This is a debug message");

Answer 3

Simple.

Add a little bash script that finds all references to console.log and deletes them.

Make sure that this batch script runs as part of your deployment to production.

Don't shim out console.log as an empty function, that's a waste of computation and space.

Answer 4

This code works for me:

if(console=='undefined' || !console || console==null) {
  var console = {
    log : function (string) {
        // nothing to do here!!
    }
  }
}

Answer 5

Since 2014, I simply use GULP (and recommend everyone to, it's an amazing tool), and I have a package installed which is called stripDebug which does that for you.

(I also use uglify and closureCompiler in production)

There's a Babel Macro that automatically removes all console statements:
