What logger to use for Firebase Functions?

Question

Firebase recommends in their documentation to use their cloud functions logger SDK. Does anyone recommend to use another logger such as Winston instead?

  const functions = require("firebase-functions");
  functions.logger.log("Hello from info");

Answer 1

I personally prefer to use directly Cloud Logging library as it gives more customization if needed. ( Firebase logging relies on it)

If you prefer Winston you have an implementation for Google Cloud. https://cloud.google.com/logging/docs/samples/logging-winston-quickstart

I would choose one or another depending on "portability". If you plan to stick with Firebase/Google Cloud I will go for Cloud Logging as it will work also with other Google services (ex. Cloud Run). If not, Winston is almost and standard.
