Class ClientTags

java.lang.Object
net.fabricmc.fabric.api.tag.client.v1.ClientTags
public final class ClientTags extends Object
Allows the use of tags by directly loading them from the installed mods.

Tags are loaded by the server, either the internal server in singleplayer or the connected server and synced to the client. This can be a pain point for interoperability, as a tag that does not exist on the server because it is part of a mod only present on the client will no longer be available to the client that may wish to query it.

Client Tags resolve that issue by lazily reading the tag json files within the mods on the side of the caller, directly, allowing for mods to query tags such as ConventionalBlockTags even when connected to a vanilla server.
