Question

Trying to implement a Mongoose model in Typescript. Scouring the Google has revealed only a hybrid approach (combining JS and TS). How would one go about implementing the

Answer 1

Just add another way (@types/mongoose must be installed with npm install --save-dev @types/mongoose)

import { IUser } from './user.ts';
import * as mongoose from 'mongoose';

interface IUserModel extends IUser, mongoose.Document {}

const User = mongoose.model('User', new mongoose.Schema({
    userName: String,
    password: String,
    // ...
}));

And the difference between interface and type, please read this answer

This way has a advantage, you can add Mongoose static method typings:

interface IUserModel extends IUser, mongoose.Document {
  generateJwt: () => string
}
