猫鼬打字稿方式...? [英] Mongoose the Typescript way...?

问题描述

尝试在Typescript中实现Mongoose模型.对Google的调查只揭示了一种混合方法(结合JS和TS).在没有JS的情况下，如何以我比较幼稚的方式实现User类?

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 User class, on my rather naive approach, without the JS?

想要没有行李的IUserModel.

Want to be able to IUserModel without the baggage.

import {IUser} from './user.ts';
import {Document, Schema, Model} from 'mongoose';

// mixing in a couple of interfaces
interface IUserDocument extends IUser,  Document {}

// mongoose, why oh why '[String]' 
// TODO: investigate out why mongoose needs its own data types
let userSchema: Schema = new Schema({
  userName  : String,
  password  : String,
  firstName : String,
  lastName  : String,
  email     : String,
  activated : Boolean,
  roles     : [String]
});

// interface we want to code to?
export interface IUserModel extends Model<IUserDocument> {/* any custom methods here */}

// stumped here
export class User {
  constructor() {}
}

推荐答案

这是我的方法:

export interface IUser extends mongoose.Document {
  name: string; 
  somethingElse?: number; 
};

export const UserSchema = new mongoose.Schema({
  name: {type:String, required: true},
  somethingElse: Number,
});

const User = mongoose.model<IUser>('User', UserSchema);
export default User;
