What type should be used for a Mongoose collection model in TypeScript?

Hello everyone, I am new to TypeScript and I am trying to create an Auth controller class that requires a mongoose model in the constructor. However, I am struggling to determine the datatype for the mongoose model.

When I checked the datatype for the mongoose model, it showed: 

const model: Model<Document, {}>

  • After analyzing this, I assumed that Model is the type that needs to be specified

This is how I attempted to define the constructor:

import { Model } from "mongoose";

class AuthController {
  constructor(userModel: Model) {}
}

  • Unfortunately, I encountered this error message: 

    Generic type 'Model<T, QueryHelpers>' requires between 1 and 2 type arguments.t

  • I would appreciate some guidance on this issue as I tried to avoid using the any datatype to ensure that the constructor accepts only specific parameter types

Answer №1

To tackle this issue effectively, you can employ the following approach:

Model<UserDocument>

By defining UserDocument as a type that extends mongoose's Document type, such as:

import { Document } from 'mongoose';
UserDocument = Document & { email: string } // Insert any necessary user fields here

Alternatively, you could export your User Model from its respective file:

export default mongoose.model<UserDocument>('User', UserSchema)

Subsequently, utilize this exported model in your constructor like so:

import UserModel from "./user-model";

class AuthController {
  constructor(userModel: UserModel) {}
}
