quilt-serverside-mods VS polymer

not a jobs one, no. you can check out the serverside mod list here https://serverside.infra.link/

Have a look at this list. It's got a ton of useful server-side mods which you can use on your server.

To be honest, the natural path for those that come from Bukkit and derivates for the future is to either switch to datapacks, migrate altogether to Bedrock (that already have interesting advances on its addon/pack system) or switch to Fabric server-only mods - There is a lot of possibilities already and there is also Polymer project that aims to "convert" some classic mods to server-side-only, so at the end maybe OP should look at it all and forget the Sponge thing.

This seems like a decent shop mod, for a larger list of mods you can look here. Another shop mod I found was https://modrinth.com/mod/diamond-economy

Once you have your server OS installed, look through the performance section of Quilt Serverside Mods (even though it says Quilt all the mods are Fabric compatible). Also make sure to set sync-chunk-writes to false in your server.properties.

I have been using this list to find some optimization mods but some mods in the performance sections seems to break the game (eg - Very Many Players ).

Here’s a good resource for server-side mods, some of them are for quilt but quite a few are fabric mods (originally the list was only fabric mods, also quilt is a fork of fabric, so if you wanted to give it a go, it has most of the same benefits fabric does)

Fabric can, with Polymer (the mods need to be written with it) 😀 you can find it here

Power networks manages to work without being installed on the client by using the polymer library and the new display entities introduced in minecraft 1.19.4. Connections between coils are rendered as leads, which mostly work.

It injects it with custom nbt and also a texture pack for textured items/blocks. From my experience with it, it works great. There are already a few existing mods with it that you can check out all the mods at: https://github.com/Patbox/polymer/blob/dev/1.19.3/MODS.md

i assume this is for a server, it would be best, in this case, to switch to a modded server, fabric will likely be better than anything based on bukkit in this case, you should be able to use https://github.com/Patbox/polymer to allow for an optional dependency for a mod that adds your custom blocks while vanilla clients joining the server would be displayed a fallback block. I've not personally used it but by the sounds of it, this is what this dependency can do. https://github.com/Patbox/UniversalGraves

There's https://github.com/Patbox/polymer also you can join the serverside fabric discord for more help :).

The easiest way would be to look in the testmod https://github.com/Patbox/polymer/tree/dev/1.18.1/polymer/src/testmod/java/eu/pb4/polymertest
