mongoose (mongodb) Alias _id field

Question

Is it possible with mongoose use a different name, in my case uppercase \'ID\', as an alias for the schema _id field? Would I need to add a virtual or is there another way o

Answer 1

The easiest way is to specify alias in the schema:

let s = new Schema({
    _id: { type: String, alias: "ID" }
});

This automatically creates both getter and setter, so it is possible to use ID everywhere instead of _id.

Answer 2

You would use a virtual attribute for that. As in:

yourSchema.virtual('ID').get(function() { return this._id; });
