I have a mongoose model with an interface declaring it as such:
export interface IUserDocument extends mongoose.Document {
surname: string;
lastName: string;
}
export interface IUserModel extends mongoose.Model<IUserDocument> {
myStaticMethodGoesHere(signature: string): void;
}
and the corresponding mongoose schema:
const UserSchema = new mongoose.Schema({
surname: {type: String, required: true},
lastname: {type: String, required: true},
})
Now I have to define how my User is structured 2 times already (mongoose schema AND typescript interface), which isn't DRY and is inconvenient. Unfortunately, if I want to use mongoose's lean method, I have to define yet another interface:
export interface ILeanUserDocument {
_id: mongoose.Types.ObjectId;
__v: number;
surname: string;
lastName: string;
}
This is inconvenient and error prone. Is there a way for my lean interface to extend (I don't know the verb to use here) my IUserDocument interface but remove stuff from it?
