对象销毁 ES6 类

Question

How can I properly apply object destructing for the methods in ES6 classes

user.ts

import { Request, Response } from "express";

export class User {

  constructor (){
      Object.assign(this,{
          root:this.root,
          get:this.get
      })
  }  
  public  root(req: Request, res: Response) { 
    res.status(200).send({
      message: "DEFAULT request successful!!"
    });
  }
  public get(req: Request, res: Response){
    res.status(200).send({
        message: "USER request  successful!!"
      });
  }

}

export const user = new User();

And i am import like this

import  {root,get} from './user'

But it will be thrown has no exported member error

UPDATE

Based on comments i changed my export to the following

let obj = new User();

export const user = {
    root:obj.root,
    get:obj.get
}

But still the same error

You need to export root and get - destructure your export line:

export const { root, get } = new User();

If you also want to export a user:

export const user = new User();
export const { root, get } = user;

You could also just import user and manually create the functions:

import { user } from "./user";
const { root, get } = user;
