Summary

In this chapter you have learned what a passport is and strategies to configure the different parts of the passport in order to authenticate the user and store it into the request. You have also seen how to implement the different modules, AuthenticationModule and the UserModule, in order to be logged into the user and provide some endpoints accessible by the user. Of course, we have restricted the access to some data that applies the AuthenticationMiddleware and the CheckLoggedInUserGuard for more security.

You have also seen the new @nestjs/passport package, which allows you to implement in faster ways a few classes as AuthenticationService and JwtStrategy, and be able to authenticate any user on any controller method using the AuthGuard provided by the package.

In the next chapter you will learn about the Dependency Injection pattern.
