Conditional logging
Another way to solve this is to have the logs in place, but only enable them conditionally. If you enable all the logs are the time, you only get a lot of noise that won't help you. If you are using JavaScript, you can use the package debug to add logs that are active by the DEBUG environment variable.

What is the DEBUG 🐛 environment variable in Node.js, and how to use it?
Although it's used by Express, it's indeed more broadly, the way a popular NPM package called debug works, which is used internally in Express too. Under the hood, the debug package expects the DEBUG environment variable to determine what debug messages to print (could be on the console, or into a file, or into stdout to be collected by a log aggregator service).

Use the [debug npm library](https://www.npmjs.com/package/debug) to disable your logging unless someone provides the right environment variable (e.g. DEBUG=* which enables all logging)

Debug build vs Prod build
A lot of tools rely on the NODE_ENV environment variable for that, React included. Another great package that’s pretty popular is https://www.npmjs.com/package/debug You can create namespaces and then filter the logs you are interested in.
