Netstjs - multiple global guards with user access - nestjs

Question

I want to use the guard which will check the database if current user is active on each request. From the research I have done, I can use request.user only if the the guard is not global.
Options I have are:
Register guards on each controller/resolver (downside: duplicate code)
Extract and decode jwt from request.headers (jwt is then decoded twice: once from me and once under the hood (I am using AuthGuard('jwt')))
What is the best (and cleanest) solution for doing the needed filtering? Is there any better option available?
#Injectable()
export class IsUserActiveGuard implements CanActivate {
constructor(
private userService: UsersService) { }
async canActivate(context: ExecutionContext): Promise<boolean> {
const ctx = GqlExecutionContext.create(context);
const request = ctx.getContext().req;
const user = request.user;
if (user)
return await this.userService.checkActiveUser(user.id);
return true;
}
}

Answer 1

Move the checkActiveUser method to a new service, maybe some called GuardService and create a global module with GuardService as a provider, then import that global module to the root module (often called AppModule) and that's it. You can use your Guard on your application without importing the Module again.
Inside the guard you can have this code to get the token and payload
const req = context.switchToHttp().getRequest();
const authHeader = req.headers['authorization'];
const token = authHeader && authHeader.split(' ')[1];
if (token == null) throw new UnauthorizedException('Null Access Token');
try {
verify(
token,
`${this.config.get<string>('JWT_ACCESS_KEY')}`,
) as IAccess;
req.session = user; //User Session
/* Some extra validation here */
} catch (error) {
throw new ForbiddenException('Invalid Access Token');
}
return true;
