猫鼬打字的方式...？

javascript node.js typescript mongoose

尝试在Typescript中实现猫鼬模型。搜索Google只发现了一种混合方法（结合JS和TS）。如果没有JS，如何以我相当幼稚的方法实现User类？

希望能够在没有行李的情况下使用IUserModel。

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() {}
}

答案 1

我是这样做的：

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;

答案 2

如果要分离类型定义和数据库实现，则另一种方法。

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

type UserType = IUser & mongoose.Document;
const User = mongoose.model<UserType>('User', new mongoose.Schema({
    userName  : String,
    password  : String,
    /* etc */
}));
