Question

How to log these?

Answer 1

You can enable debug mode like so:

mongoose.set('debug', true); 

or add your own debug callback:

mongoose.set('debug', function (coll, method, query, doc [, options]) {  //do your thing }); 

This will log all executed collection methods and their arguments to the console.

Answer 2

You can use the following format:

mongoose.set("debug", (collectionName, method, query, doc) => {     console.log(`${collectionName}.${method}`, JSON.stringify(query), doc); }); 

or any other logger of your choice:

mongoose.set("debug", (collectionName, method, query, doc) => {     logger(`${collectionName}.${method}`, JSON.stringify(query), doc); });
