您可以将带有装饰器的 Typescript 类导出为普通类（没有装饰器）吗？

Question

Lets say I have a class like this:

import { Injectable } from '@nestjs/common';
import { IsString } from 'class-validator';
import { prop } from '@typegoose/typegoose';

@Injectable()
export class Human
{
    @prop({ unique: true })
    @IsString()
    readonly name: string;
}

The question is: can I export this class so that the receiving end gets it without the decorators, like this:

class Human
{
    readonly name: string;
}

I want to export the class (which has other dependencies for the decorators) so that the file importing it does not require the dependencies used for those decorators, such as nestjs, class-validator, and typegoose.

I'm trying to NOT write out "readonly name: string;" more than once.

So I figured it out, in part thanks to zett42.

You can define a type in typescript, so if you just make a type that is equal to the class, then export that type, you will effectively be exporting that class definition without decorators. You can also do it with interfaces , but types seem to be cleaner. However I'm not sure if types behave the same as interfaces, time to read the Typescript documentation!

With types:

export type THuman = Human;

With interfaces:

export interface IHuman extends Human {}
