NestJS codebase containing real world examples (CRUD, auth, advanced patterns, etc) that adheres to the RealWorld API spec.

---

Getting started

Installation

Clone the repository

git clone https://github.com/lujakob/nestjs-realworld-example-app.git

Switch to the repo folder

cd nestjs-realworld-example-app

Install dependencies

npm install

Copy config file and set JsonWebToken secret key

cp src/config.ts.example src/config.ts

---

Database

The codebase contains examples of two different database abstractions, namely TypeORM and Prisma.

The branch master implements TypeORM with a mySQL database.

The branch prisma implements Prisma with a mySQL database.

---

TypeORM

---

Create a new mysql database with the name nestjsrealworld
(or the name you specified in the ormconfig.json)

Copy TypeORM config example file for database settings

cp ormconfig.json.example

Set mysql database settings in ormconfig.json

{
  "type": "mysql",
  "host": "localhost",
  "port": 3306,
  "username": "your-mysql-username",
  "password": "your-mysql-password",
  "database": "nestjsrealworld",
  "entities": ["src/**/**.entity{.ts,.js}"],
  "synchronize": true
}

Start local mysql server and create new database 'nestjsrealworld'

On application start, tables for all entities will be created.

---

Prisma

---

To run the example with Prisma checkout branch prisma, remove the node_modules and run npm install

Create a new mysql database with the name nestjsrealworld-prisma (or the name you specified in prisma/.env)

Copy prisma config example file for database settings

cp prisma/.env.example prisma/.env

Set mysql database settings in prisma/.env

DATABASE_URL="mysql://USER:PASSWORD@HOST:PORT/DATABASE"

To create all tables in the new database make the database migration from the prisma schema defined in prisma/schema.prisma

npx prisma migrate save --experimental
npx prisma migrate up --experimental

Now generate the prisma client from the migrated database with the following command

npx prisma generate

The database tables are now set up and the prisma client is generated. For more information see the docs:

• https://www.prisma.io/docs/getting-started/setup-prisma/add-to-existing-project-typescript-mysql

---

NPM scripts

• npm start - Start application
• npm run start:watch - Start application in watch mode
• npm run test - run Jest test runner
• npm run start:prod - Build application

---

API Specification

This application adheres to the api specifications set by the Thinkster team. This helps mix and match any backend with any other frontend without conflicts.

Full API Spec

More information regarding the project can be found here https://github.com/gothinkster/realworld

---

nestjs-realworld-example-app's Issues

'aticles' mispelled lead to routes not protected

While playing with nestjs realworld, I found out that you can create post without user authenticated due to misspelled aticles in article.module.ts https://github.com/lujakob/nestjs-realworld-example-app/blob/master/src/article/article.module.ts#L24-L27

Due to this.userRepository.findOne(userId) where userId is null, return the first user instead of throwing an error, it doesn't help detecting that the user does not exist.

I recommend using this.userRepository.findOne({ where: { id: userId } });
See this TypeORM issues: typeorm/typeorm#2500

Using sha256 isn't secure for password hashing

sha256 is just a message digest, so it really shouldn't be used as an example for password hashing.

You can use argon2 though, which is considered the best current password hashing algorithm.

nestjs-realworld-example-app/src/user/user.entity.ts

Line 30 in e471eed

this.password = crypto.createHmac('sha256', this.password).digest('hex');

const argon2 = require('argon2');
 
try {
  this.password = await argon2.hash("password");
} catch (err) {
  //...
}

What is the RO sufix in the interfaces?

Hello, I have a questions about the naming of the interfaces used in the project.

What exactly is the sufix RO, in the article for example, (ArticleData & ArticleRO)

I'm sorry to bother with that, but a literally can not find anything about it

Example using MongoDB instead of MySql

Is there the same example using MongoDB (maybe with Mongoose as well)?

Question about the 'RO' naming convention in the entity interfaces

I'm writing my first nestjs app (first node application for that matter) and am using this repo as one way to approach figuring out my best practices, etc. I was curious what the RO in the various interface objects stood for.

e.g. https://github.com/lujakob/nestjs-realworld-example-app/blob/2b56fb43bb99ad18cef26dcd70882b4e7c83d96d/src/article/article.interface.ts

Is it Return Object or something similar? I hate following conventions when I don't know what something means and can't explain to someone else!

Is this repository still maintained?

Many of the controllers & services do not have tests written. These would be helpful to include as examples of how to handle testing.

Improvements

This repo is a NestJS example app for the Realworld example app series. It's my first app developed with NestJS and I guess there's lots of room for improvements. I'm learning. If anybody has ideas for improvements on the code, feel free to open an issue with recommendations or fork and PR. Thanks.

@kamilmysliwiec Your work on NestJS is great. Thumbs up. We started using it for our microservice architecture in the project I'm currently working on.
If you have any improvement recommendations for this showcase app, I'd be glad to hear about it.

TypeOrmModule: Unable to connect to the database

Hi,
I am trying to make NestJs web-app to connect to a Mysql DB running in a docker container.

ormconfig.json :

{
  "type": "mysql",
  "host": "localhost",
  "port": 3306,
  "username": "root",
  "password": "rootpass",
  "database": "nestjsrealworld",
  "entities": ["src/**/**.entity{.ts,.js}"],
  "synchronize": true
}

The docker command I am using to run mysql container instance :
docker run --rm --name nest-mysql -p3306:3306 -e MYSQL_ROOT_PASSWORD=rootpass -e MYSQL_DATABASE=nestjsrealworld -d mysql

The problem I get is it cannot to DB :/

[Nest] 18963   - 2019-07-02 2:35 PM   [TypeOrmModule] Unable to connect to the database. Retrying (1)... +97ms
Error: ER_NOT_SUPPORTED_AUTH_MODE: Client does not support authentication protocol requested by server; consider upgrading MySQL client

I have checked on the Mysql container logs it is ready for connections...

Thanks for your help.

Article creation leads to "Unhandled Rejection (TypeError): Cannot read property 'slug' of undefined" on browser

At c1c2cc4 typeorm ormconfig.json is:

{
  "type": "mysql",
  "host": "localhost",
  "port": 3306,
  "username": "user0",
  "password": "pass0",
  "database": "nestjsrealworld",
  "entities": ["src/**/**.entity{.ts,.js}"],
  "synchronize": true
}

I manually setup that database and grant access to that user.

No errors show on server terminal throughout this reproduction. I verify that tables are created fine on MySQL so connection seems fine.

I start https://github.com/gothinkster/react-redux-realworld-example-app/tree/9186292054dc37567e707602a15a0884d6bdae35 for the frontend. I have already tested it with several backends locally and it worked fine indicating that the frontend is OK.

Then browser:

• create a new user
• login
• attempt to create a new article

After clicking the submit button, I am redirected to an error page on the browser:

The official tests

Hey there,

thanks for the work.
I've just run this project vs the official RealWorld API Tests : I would suggest to use these for testing.

[ Currently they return one false negative ( I had corrected that in the testcode already) but there are 2 PRs for that, e.g. https://github.com/gothinkster/realworld/issues/309 ]

There are a few problems like with the relations.
It looks like this

I have corrected the bugs and it looks like this

I'd prefer to make a fork and change it there so that you can review the code before merging anything.

favorited field is not present in the articles list.

favorited field is not present in the articles list. This makes it incompatible with the frontend apps while the real api has the favorited field when returning the articles.

Why is ValidationPipe decorated with `@Injectable` if it is never injected?

Is this necessary? I am new to NestJs so am scrutinising every bit of example code, and I couldn't figure out why ValidationPipe was decorated with @Injectable

Create Users Route /api/users/ [POST]

Hey guys,

I downloaded this package and I was trying to create a user sending POST args to the route

localhost:3000/api/users

with the following body arguments via POSTMAN:

{
"username": "abc123",
"email":"[email protected]",
"password": "1234567890"
}

...but I always receive a 400 - with no data submitted. What am I'm doing wrong? Postman issue or a route error?

Just for your information - the route localhost:3000/api/articles [GET] works fine receiving a 200 code and some sample data pushed to the database directly.

Thanks in advance,
Oliver

PUT request on `/user` fails because of lines 7-9 of user.decorator.ts

I don't understand the purpose of that block, but what I know is that the PUT request works if I comment those lines of code.

The error is about getting the user's id as undefined.

if (!!req.user) {
   return !!data ? req.user[data] : req.user;
}

BUG: Argon2 on "arch":"win64"

Impossible to find a compatible version of argon2 from a windows (x64) arch.
I suggest to revert this commit ae45f2e3329ca0d7d263ae29ce21e0c738f5ee34
Also no tags available here, can't report it as a bug, and can't bind a PR 😭

Why is Passport included?

Great project here! Really helping me out as I'm making my first transition from Express to Nest (well, not fully since Nest uses Express).

I see in package.json and auth.middleware.ts that the Passport library is imported, but do not see it being used anywhere. Might be worth removing to avoid confusion from those reading through the code?

Prisma has no `favouritesCount`

I just noticed the Prisma version of this app has no favouritesCount property on the articles.
This makes it incompatible with all front ends.

Nestjs 6 upgrade

It would be nice to upgrade nestjs for this example app

Debugging The App

How can I debug this app?

i have a problem about the controllers

  @Post(':slug/favorite')
  async favorite(@Headers('authorization') authorization: string, @Param('slug') slug) {
    return await this.articleService.favorite(this.getUserIdFromToken(authorization), slug);
  }

  @Delete(':slug/favorite')
  async unFavorite(@Headers('authorization') authorization: string, @Param('slug') slug) {
    return await this.articleService.unFavorite(this.getUserIdFromToken(authorization), slug);
  }

like this section is it feels like have a tiny redundance.

I mean that can auth be taken in middleware like koa, and we don't need to pay attention to it?

Update prisma to the new version

Can you update the prisma, I tried, and broke the code

The 'tag.controller.spec.ts' fails – possible problem and fix

Hi there!

The example is just awesome, however when I run the test in my environment, an error occurs like in the screen below.

---

I found the code below fixes that problem.

describe('findAll', () => {
it('should return an array of tags', async () => {
const tags : TagEntity[] = [];
const createTag = (id, name) => {
const tag = new TagEntity();
tag.id = id;
tag.tag = name;
return tag;
}
tags.push(createTag(1, 'angularjs'));
tags.push(createTag(2, 'reactjs'));
jest.spyOn(tagService, 'findAll').mockImplementation(() => Promise.resolve(tags));

const findAllResult = await tagController.findAll();
expect(findAllResult).toBe(tags);
});
});

---

Is there any other solution to the issue I met, to make the test work properly, better than providing the quite complex mock implementation?

Cannot authenticate

when I Post with authenticate header, code don't run to return function. pls help me
@Injectable()
export class AuthMiddleware implements NestMiddleware {
constructor(private readonly userService: UserService) {}

use(): (req: Request, res: Response, next: NextFunction) => void {

return async (req: Request, res: Response, next: NextFunction) => {
  if (req.headers.authorization && (req.headers.authorization as string).split(' ')[0] === 'Token') {
    const token = (req.headers.authorization as string).split(' ')[1];
    const decoded: any = jwt.verify(token, SECRET);
    const user = await this.userService.findById(decoded.id);

    if (!user) {
      throw new HttpException('User not found.', HttpStatus.UNAUTHORIZED);
    }

    req.user = user.user;
    next();

  } else {
    throw new HttpException('Not authorized.', HttpStatus.UNAUTHORIZED);

  }
};

}
}

Is this repository still maintained?

Update user password

Route PUT /user does not hash password on updates. For example, if you issue PUT /user with body

{
    "user": {
        "password": "newpassword"
    }
}

Then it will write "newpassword" in password column instead of password hash.

Transaction management Question

I am trying to understand how to best implement Transaction management in NestJs but no luck so far.
How does transaction rollback happen when you are inserting in multiple tables and one of the insert succeeds and other one fails.
Example in nestjs-realworld-example-app/src/article/article.service.ts

In create(), if this succeeds

   const newArticle = await this.articleRepository.save(article);

but this fails

  await this.userRepository.save(author);

Article GET methods conflict

articles/feed doesnt work because there articles/:slug comes first

Cannot read property 'articles' of undefined when create new article

I got error when create new article, here is my code:

        let article = new ArticleEntity();
        article.title = articleData.title;
        article.description = articleData.description;
        article.slug = this.slugify(articleData.title);
        article.tagList = articleData.tagList || [];
        article.comments = [];

        const newArticle = await this.articleRepository.save(article);

        const author = await this.userRepository.findOne({ where: { id: userId } });

        if (Array.isArray(author.articles)) {
            author.articles.push(article);
        } else {
            author.articles = [article];
        }

where userId returns undefined. Could anyone help me out? thank you.

'articles' routes order

"/articles/feed" will never get called because this request is going to be captured by the "/articles/:slug" route handler. Maybe this route should be registered before "/articles/:slug".
