Item Components
Change the default components for items! Server-side and data-driven, refreshes on /reload! (and does it properly)
I don't know my version or loader
Open the Minecraft launcher and look at the profile you play on — it names both, like fabric-loader-1.21.4. The version also shows in the bottom-right corner of the game's main menu.
No loader in the profile name? Then it's plain Minecraft, and these mods won't run — you need Fabric or NeoForge installed first.
Item Components

⚙️ Datapack creation
Components on (an) item(s) can be changed by adding an entry under <namespace>:item_components/<path>.json.
Entries have 3 fields, all optional:
parents: an ID or an array of IDs- The entries to inherit. Note that only the parent's parents and parent's components are inherited, not the parent's targets.
targets: an item ID, an item tag suffixed with '#' or an array of item IDs- The items to apply the component changes to.
components: a component changes object- The component changes to apply to the items.
