mongoose lean query, virtuals not showing

i found a solution you can use mongoose-lean-virtuals plugin

https://www.npmjs.com/package/mongoose-lean-virtuals

lean queries return raw MongoDB driver response as a plain js object. So, there are no getters, setters, virtuals or other "Mongoose magic" in it. See Api docs for more info.

The point of lean queries is to return your objects as fast as possible. If you need virtuals - use ordinary Mongoose queries.

As for aggregation, it's 100% MongoDB feature and Mongoose can't control it. So, when you calling aggregate from Mongoose it works the same as aggregate in MongoDB console. aggregate can't operate with virtuals, because there are no such fields in your database. Mongoose can't even cast your aggregation query according to your schema (like it's doing with findOneAndUpdate arguments), because aggregation changes the shape of the document on each step. See Mongoose API Docs and MongoDB Docs for more info.
