Nest: Cannot find module

[Tochemey]

Hello I have a class that I have created and put it in a custom folder in the src folder. It is not a nestjs module nor a provider just a helper class that I can instantiate and use. However when I run the app I got the following error:

[npm run start:dev

This is the class I am instantiating in a controller:

export class JsonResult<T> {
  readonly status: string;
  readonly data: T;

  constructor(status: string, data: T) {
    this.status = status;
    this.data = data;
  }
}

and my controller implements this abstract class:

export abstract class ApiController {
  failed(): void {
    throw new HttpException(
      {
        status: ApiStatus.FAILED,
        data: {},
      },
      HttpStatus.INTERNAL_SERVER_ERROR,
    );
  }

  notFound(): void {
    throw new HttpException(
      {
        status: HttpStatus.NOT_FOUND,
        data: [],
      },
      HttpStatus.NOT_FOUND,
    );
  }

  badRequest(message: string): void {
    throw new HttpException(
      {
        status: HttpStatus.BAD_REQUEST,
        data: {
          message,
        },
      },
      HttpStatus.BAD_REQUEST,
    );
  }

  success<T>(data: T): JsonResult<T> {
    return new JsonResult<T>(ApiStatus.SUCCESS, data);
  }
}

Please, use StackOverflow for such questions.

very rude

@SamiHK we are using GitHub to track bugs, feature requests, and potential improvements. It's really difficult to keep GitHub clean and we don't have people that would spend their free time answering questions that shouldn't be located here. For support questions, we encourage people to use our Discord channel or StackOverflow.

I have followed StackOverflow: https://stackoverflow.com/questions/53963007/error-while-running-nestjs-in-production-mode-cannot-find-module

Event correct answer was not able to solve this issue.
It was working correctly on the local environment but as soon as I hit npm run start:dev it shows the exact same error the above person was talking about.

Maybe you can train a dozen juniors who can help on these issues NEST is growing fast.
I appreciate your hard work 💯 but it is just a turn-off for a developer if he/she has to spend hours on a simple problem.
Maybe this is a bug and needs a fix.

@Tochemey
Either your tsconfig.json is faulty, the import path or the filename ./json.result.js is incorrect. However, this is most likely not a Nest related problem so please as already mentioned use StackOverflow

@SamiHK

turn-off for a developer if he/she has to spend hours on a simple problem.

We fully understand that - we have all been there - but we can quite frankly not be a support desk for every question. These GitHub issues are here for collecting bugs / features / enhancements (and discussions to some degree) related to the code itself.

This issue is most likely not a problem with NestJS code - that is why we redirect it to StackOverflow or other channels because there are way more people who are happy to help there.

Maybe you can train a dozen juniors

Most open source projects do not work like that. Most contributors are volunteers who actually work for free <3. Nest does have super generous donators, but it is far from being sufficient to pay dozens of juniors.
