Mongoose NPM package is HUGE and contains logs

I'm using mongoose to connect to a mongo database.

I'd like to understand why node_modules/mongoose goes over 1gb... And when I check what's inside, I get 3 huge folders (31000, 31001, 31002) with what seems to be logs, even with a fresh reinstall..

$ rm -Rf node_modules/mongoose
$ npm i mongoose
$ ls -al node_modules/mongoose/tools/31000/journal
total 614400

What is it ? How do I get rid of it ?
