nestjs-api-tutorial's Issues

auth.service.ts decrepated import

This line is decrepated:
import { PrismaClientKnownRequestError } from '@prisma/client/runtime';

It work with:
import { PrismaClientKnownRequestError } from '@prisma/client/runtime/library';

getBookmarks By UserId dont work

When i try to run the test for getBookmarks i get an error :

Unknown arg userId in where.userId for type BookmarkWhereInput. Did you mean id? Available args:
type BookmarkWhereInput {
AND?: BookmarkWhereInput | List
OR?: List
NOT?: BookmarkWhereInput | List
id?: IntFilter | Int
createdAt?: DateTimeFilter | DateTime
updatedAt?: DateTimeFilter | DateTime
title?: StringFilter | String
description?: StringNullableFilter | String | Null
link?: StringFilter | String
}

this is my prisma model :

generator client {
  provider = "prisma-client-js"
}

datasource db {
  provider = "postgresql"
  url      = env("DATABASE_URL")
}

model User {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  email String @unique
  hash  String

  firstName String?
  lastName  String?

  bookmarks Bookmark[]

  @@map("users")
}

model Bookmark {
  id        Int      @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  title       String
  description String?
  link        String

  userId Int
  user   User @relation(fields: [userId], references: [id])

  @@map("bookmarks")
}

why i got this error?

Does it auto sends the refresh token?

Hello vlad, you are really amazing and I love you content very much, the way you tech, its really wonderful way of teaching,

love your videos,

and I have a question,

We have talked about refresh token and auth token,

Now I want to implement this with next.js for the frontend, and now how do I handle the refresh token request, and setting up dynamic contents for the authorized users ? and since it expires token in some time, so how to auto request the refresh token etc?

Can you please tell me how to do this? A guide on this,

This will save my life so much!

Prisma Error

I am getting this error when trying to run nest js

Error [ERR_REQUIRE_ESM]: require() of ES Module C:\Users\shaun\node_modules@angular\core\fesm2015\core.mjs not supported.
Instead change the require of C:\Users\shaun\node_modules@angular\core\fesm2015\core.mjs to a dynamic import() which is available in all CommonJS modules.

.expectBodyContains('$S{bookmarkId}'); can lead to unexpected false positive results

expectBodyContains doesn't seem to care about where the provided value appears. In case the code is failing for some reason but by chance the user id is same as the bookmark id, then the test will succeed. This is particularly a likely unwanted outcome, if cleanDb also resets all auto increment values. (first user and bookmark will have 1 as id).

For instance, I have also stored the userId in pactum at "Get me" test and tested against userId at "should get bookmark by id", which succeeded. Even worse, the number may match with other fields, e.g. createdAt, updatedAt etc.

.expectJsonMatch({id: '$S{bookmarkId}'}) would have been the correct test here.

Argument where of type UserWhereUniqueInput needs at least one argument

Issue Description

The strategy validate method is using only id in the where clause but when doing the call for /users/me it getting the error:

[Nest] 41843  - 04/11/2023, 8:49:30 PM   ERROR [ExceptionsHandler] 
Invalid `this.prisma.user.findUnique()` invocation in
/Users/edsonmartins/dev/nest/freeCodeCamp/GHTA143_b-s/nestjs-api-tutorial/src/auth/strategy/jwt.strategy.ts:17:41

  14   });
  15 }
  16 async validate(payload: { sub: number; email: string }) {
→ 17   const user = await this.prisma.user.findUnique({
         where: {
       ?   id?: Int,
       ?   email?: String
         }
       })

Argument where of type UserWhereUniqueInput needs at least one argument. Available args are listed in green.

Note: Lines with ? are optional.

Looking to solve this, I have changed my local code as:

async validate(payload: { sub: number; email: string }) {
    const user = await this.prisma.user.findUnique({
      where: {
        id: payload.sub,
        email: payload.email,
      },
    });
    delete user.hash;
    return user;
  }

or using findFirst instead of using findUnique.

User Prisma schema

model User {
  id Int @id @default(autoincrement())
  createdAt DateTime @default(now())
  updatedAt DateTime @updatedAt

  email String @unique
  hash String

  firstName String?
  lastName String?

  bookmarks Bookmark[]

  @@map("users")
}

Could you share if the approach using findUnique with both fields or findFirst with id only is correct or is there something more to use findUnique with only the id?

Code in the jwt.strategy.ts file is not working properly

I am creating this issue just in case if someone is following the nodejs tutorial on freecodecamp and facing issue while implementing the JWT strategy.

mikenicholson/passport-jwt#153

export class JwtStrategy extends PassportStrategy(Strategy) {
  constructor(private configService: ConfigService) {
    super({
      secretOrKey: configService.get('JWT_SECRET'),
      jwtFromRequest: ExtractJwt.fromAuthHeaderWithScheme('Bearer'), //instead of ExtractJwt.fromAuthHeaderAsBearerToken()
      ignoreExpiration: true,
    });
  }

  validate(payload: any) {
    console.log(payload);
    return payload;
  }

While calling the request you can normally pass Authorization header as Bearer ${token}

readme.md file does not contain how to run whole environment

Dear Vlad,

I saw your video on Youtube (Free Code Camp one) and the tutorial is so cool - anyway - the readme file could be a bit more comprehensive with explanation how to really run the whole environment :-)

Thank you!

whitelist: true option not working for new ValidationPipe

I have been trying to reproduce the validation part using dtos and global pipes but for some reason the whitelist option is not working. I know there have been ground breaking changes with nest, and their document hasn't been updated for the same, but the issue persists.

Here is my auth.dto.ts:

import { IsEmail, IsNotEmpty, IsString } from "class-validator"

export class AuthDto {
    @IsEmail()
    @IsNotEmpty()
    email: string;

    @IsString()
    @IsNotEmpty()
    password: string;
}

Here is my main.ts:

import { NestFactory } from '@nestjs/core';
import { AppModule } from './app.module';
import { ValidationPipe } from '@nestjs/common';

async function bootstrap() {
  const app = await NestFactory.create(AppModule);
  app.useGlobalPipes(new ValidationPipe({
    whitelist: true,
  }));
  await app.listen(3333);
}
bootstrap();

Parsing error: Cannot read file 'c:\users\panka\source\web repos\tsconfig.json'.eslint

Encounter with this problem at all files.

Error Handling for Prisma

the import from the tutorial

import { PrismaClientKnownRequestError } from '@prisma/client/runtime';

Is not working as expected, instead when I import like below as per the documentation it works fine:

import { Prisma } from '@prisma/client';

// and try to match error instance in this way
if (error instanceof Prisma.PrismaClientKnownRequestError) {
        console.log(error.message);
        if (error.code === 'P2002') {
          throw new ForbiddenException('Credentials taken');
        }
      }

Hope this helps if anyone following along faces the same issue.
