Best way to sync datapack info to client? [1.18.2]

[JayZX535]

Hey all,

I've been working a lot with datapacks lately, and I'm wondering what the most efficient way to get said data from server to client is.  I'm currently using packets, but given that a lot of the data I'm storing involves maps along the lines of Map<ResourceLocation, CustomDataType>, it can easily start to get messy if I need to transmit a lot of that data all at once.

Recently I started looking into the ReloadableServerResources class, which is where Minecraft stores its built-ins.  I see you can access it via the server from the server's resources.managers, and it seems like this can be done even from the client to appropriately retrieve data from the server, unless I'm misunderstanding.  However, from what I can tell, this only works via built-in methods such as getRecipeManager() or getLootTables(), etc.  These are all SimpleJsonResourceReloadListeners, just like my datapack entries are, so it seems like it could be possible for me to access my datapack entries similarly?  But I don't see anywhere in ReloadableServerResources that stores loaded modded entries, so either I'm looking in the wrong place or it doesn't seem to be a thing.

Are packets really the best way of doing this, or am I missing a method that would let me use ReloadableServerResources or something similar?

As long as the packets you are sending aren't lost, there's nothing wrong with what you're currently doing. Although, this sounds like something that would benefit from you making your own datapack registry instead of trying to arbitrarily sync static maps. Check out `DataPackRegistryEvent.NewRegistry`.
