impact on production, how to use debug (use as devDependency?)

I first used debug as devDependency, but obviously that would not work.

What is the perf impact on a debug call in production, i.e. process.env.DEBUG not set or NODE_ENV = production?

Is it recommended to wrap debug in a separate file and use require('./debug.js'), that way it could be a devDependency.

if (!!process.env.DEBUG || process.env.NODE_ENV != 'production'){
    try {
        module.exports = require('debug');
        return;
    } catch(e){}
}

module.exports = function(){
    return function(){};
};

Would anybody recommend using or not using debug like that?

Thanks for your help

var debug = require('debug')('debug');
console.log(debug.toString());
// logs
// function disabled() {
//  }

OK without DEBUG it is actually an empty function, (if my test is correct). So no impact other than calling an empty function. If this is correct, I guess my only question is, is this correct and do people use debug as regular dependency.

The impact of calling debug without process.env.DEBUG is negligible, as if I understand it correctly, it is like calling an empty function everywhere. Closing…
