Console.log in a production app using node.js, express and PM2

I'm using console.log for debugging some information in my web app using node.js, expressjs and PM2. All is working fine :)

I want to know if my web app can have performance problems in production if I use console.log this:

var myVariable = "Enter in this section of code";
console.log(myVariable);

I have read about console.log is synchronous and can affect to my performance... if this is real in this moment (I'm using Express 4), how can I remove these console.log in different environments like production?

I'm using PM2 (pm2 logs command) to watch the logs and pm2 flush to clean the logs.

Thanks.

You could use winston for logging , you could configure transport depending on your env , for example you could use Console and File tranports in development and just File in production. PD: pm2 takes data from std log(console)
