Custom GetUser Decorator

[dyaliCode]

I guess with last version of nestjs, couldn't get req.user
because you will recive undefined data

make sure and test with last version !

Controller :

@Post('/test')
  @UseGuards(AuthGuard())
  test(@GetUser() user) {
    console.log('user', user);
  }

Decorator:

export const GetUser = createParamDecorator(
  (data, req): User => {
    return req.user;
  },
);

Console Output:
user undefined

So change code custom decorator to :

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

Yeah. This one had me confused for a bit. I guess it's wise to always check the docs for the latest information. Apparently, NestJS changed the syntax for createParamDecorator a while ago.

I had the same issue until I added ExecutionContext.

try this code

import { createParamDecorator, ExecutionContext } from '@nestjs/common';
import { User } from './user.entity';

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