Typescript 与棱镜

Question

I'm completely new to Typescript.

I've started to work with Prisma and, coming from Sequelize, I miss simply writing stuff eg user.update({... }) . It seems that Prisma returns just plain objects, and not classes, so I came up with this:

import { Prisma, User as PrismaUser } from '@prisma/client';
import prisma from './path-to-prisma-instance';

class User {
  constructor(data: PrismaUser) {
    Object.assign(this, data);
  }

  update = async (props: Prisma.UserUpdateArgs) => {
    const data = await prisma.user.update({
      ...props,
      where: { id: this.id } // Property 'id' does not exist on type 'User'
    });
    return new User(data);
  };
}

I'm getting that Property 'id' does not exist on type 'User' .

How am I able to fix this?

I don't understand why you need to return a class instead of an object but if you want to achieve that you should create your class User with the same properties of the plain object returned by

await prisma.user.update()

your class User does not have any property .
