In this course, you will cover NestJS, a framework used to build efficient and reliable server-side applications. Using this framework, developers can make highly scalable backend applications that can be consumed with any type of frontend. 

You will start the course by learning the foundational blocks of NestJS, such as understanding modules, services, and controllers. Next, you will learn how to build REST API, validation and error handling. You will also learn database integration using TypeORM, app configuration using environment variables, authentication, and authorization using JWT tokens. You will complete this course by learning automated testing and application logging.

After completing this course, you will be equipped with all the necessary skills to build scalable backend applications using NestJS, and that will also advance your career in backend development.

Building a Back-End Application with NestJS

What is the primary purpose of using `nestjs-pino` in a NestJS application?

What is the primary purpose of using <code>nestjs-pino</code> in a NestJS application?

```typescript
LoggerModule.forRoot({
  pinoHttp: {
   redact: ['req.headers.authorization']
   }
})
```

```typescript
LoggerModule.forRoot({
  pinoHttp: {
    hidden: "req.headers.authorization"
  }
})
```

```typescript
LoggerModule.forRoot({
  pinoHttp: {
    serializers: {
      req(req) {
        return req.headers.authorization;
      }
    }
  }
})
```

```typescript
LoggerModule.forRoot({
  pinoHttp: {
    serializers: {
      req(req) {
        delete req.headers.authorization;
        return req;
      }
    }
  }
})
```
