Complete example

Thanks for contribution.

Does kv satisfies expected type for storage? I think it should since kv extends bare resis class, but just to be sure.

[PonomareVlad]

@Satont It looks like that

I checked all the methods of the session plugin and found only one incompatibility related to JSON automatic deserialization

Therefore, without changing the plugin code, you can disable this parameter in the Redis instance:

instance.opts.automaticDeserialization = false;

Ok, thanks.
