How can I generate an ObjectId with mongoose

Question

I d like to generate a MongoDB ObjectId with Mongoose  Is there a way to access the ObjectId constructor from Mongoose    This question is about generating a new ObjectId from scratch  The generated ID is a brand new universally unique ID  Another question asks about creating an ObjectId from an existing string representation  In this case  you already have a string representation of an ID   it may or may not be universally unique   and you are parsing it into an ObjectId

I needed to generate mongodb ids on client side   After digging into the mongodb source code i found they generate ObjectIDs using npm bson lib   If ever you need only to generate an ObjectID without installing the whole mongodb   mongoose package  you can import the lighter bson library    const bson   require  bson    new bson ObjectId       5cabe64dcf0d4447fa60f5e2   Note  There is also an npm project named bson-objectid being even lighter
