kandi X-RAY | nestjs-auth Summary
Authentication and authorization on the web sucks. There, I said it. I don't mean the initial login process, though that kinda stinks too--we've got the awesome Passport library to help us out there, though, and it really isn't that hard to write even OIDC or SAML correctly by hand. What sucks is everything past that point. There are some interesting tools out there like Open Policy Agent that are great if you want to wrangle a microserviceful universe--but most applications don't need microservices, most applications don't need to add a step to either their dev setup or their prod environment to go configure a spooky-action-at-a-distance service wedged into their environment--and most developers need something that gets out of the way so they can concentrate on building the thing they actually want to build.

QUESTION
I am new to nest js and I am trying to implement authenticating with nest js using JWT Token. I flow This article to implement my authenticating code.
When I run the code I get an error like this.
**
[Nest] 16236 - 01/29/2022, 7:16:06 PM ERROR [ExceptionHandler] Nest can't resolve dependencies of the AuthenticationService (?, JwtService, ConfigService). Please make sure that the argument UsersService at index [0] is available in the AuthenticationModule context. Potential solutions:
- If UsersService is a provider, is it part of the current AuthenticationModule?
- If UsersService is exported from a separate @Module, is that module imported within AuthenticationModule? @Module({ imports: [ /* the Module containing UsersService */ ] })
**
And I have no idea what is wrong with my code.
This is my UserModule :

Install nestjs-auth
Once you've got your module wired up, you need to attach the authentication and the authorization interceptors to your application. There are two ways to do this; one is way better than the other. It's a little long to put here. Please take a look at the example project. I'm of two minds about global interceptors and guards. You have to replicate them in testing situations (please remember to add this to your E2E tests, too!) and that can lead to some confusion. On the other hand, this is the only way to assert "everything is authenticated and authorized by default".
