Optional authentication in Nest.js with @nestjs/passport

I have a route that needs to be used by authenticated and unauthenticated users. I use @UseGuards(AuthGuard('jwt')) to enable authentication but it prevents any unauthenticated user to access the route (normal).

How can I allow unauthenticated users to also access the route ?

It seems that there's no options that I can pass to AuthGuard in order to retrieve them in my passport strategy.

You can just create your own AuthGuard for example by extending the existing one:

export class OptionalJwtAuthGuard extends AuthGuard('jwt') {

  // Override handleRequest so it never throws an error
  handleRequest(err, user, info, context) {
    return user;
  }

}

And then use this one on your controllers instead:

@UseGuards(OptionalJwtAuthGuard)
