NestJs - Custom decorator

• createParamDecorator 를 통해 custom decorator를 만들 수 있다.

import { createParamDecorator, ExecutionContext } from '@nestjs/common';

export const User = createParamDecorator(
  (data: unknown, ctx: ExecutionContext) => {
    const request = ctx.switchToHttp().getRequest();
    return request.user;
  },
);

// 사용
@Get()
async findOne(@User() user: UserEntity) {
  console.log(user);
}
