Caching Engines

[viztea]

As of right now, neocord only has support for memory caching... I'd like to add ways to use different methods like redis, mongodb, or any other database. But I have no idea how to do so.

Setup?

This is how I would like it to look (typescript):

import { Client, DiscordStructure } from "neocord";
import { RedisDataEngine, Sweepers } from "@neocord/engines";

const client = new Client({
  data: {
    engines: [
      new RedisDataEngine({
        handles: new Set()
          .add(DiscordStructure.Message)
          .add(DiscordStructure.Presence)
        sweepers: {
          [DiscordStructure.Message]: Sweepers.Message({
            lifetime: "30m",
            interval: "5m"
          })
        }
      })
    ]
  }
});

So here we have imported the Client and DiscordStructure.

The DiscordStructure enum is used to identify structures that can be cached within neocord like a Message, Role, etc...

We have also imported the Redis Data Engine and the Sweepers object.

The sweepers object contains pre-made sweepers for some of the structures.

In this case the redis data engine caches messages/presences and everything else will be stored within memory. I've also declared the sweepers option, only enabling a message sweeper which gets ran every 5 minutes and checks whether the message is older than 30 minutes and if it is it will be removed from the redis cache.

This is all just a very cool concept that might come to life but until there are more contributors this wont happen for quite a while.

The internals of the caching is what I would really like help on, I have no ideas on how this would work internally... especially with all of the different managers and stuff.
