About

Recipe Item Sync is a lightweight utility mod that makes custom datapack items and recipes visible inside JEI, REI and EMI, depending on your Minecraft version.

Many datapacks introduce custom items through components, loot tables or special crafting systems, but those items often remain invisible in recipe viewers.

Recipe Item Sync automatically discovers supported content on the server and synchronizes it with connected clients.

No client-side datapack installation required. Just install the mod and a compatible recipe viewer!

⚙️ Configuration & Commands

Server owners can customize which datapack sources are scanned, set collection limits and control synchronization.

Useful administrator commands:

/recipeitemsync status — View synchronization status
/recipeitemsync validate — Validate datapack content without syncing players
/recipeitemsync explain <virtualId> — Inspect an item’s source and recipes
/recipeitemsync give <player> <virtualId> — Give a synchronized virtual item
/recipeitemsync resync all — Resynchronize connected players
/recipeitemsync clientstatus <player> — Inspect client synchronization
/recipeitemsync dump — Generate a diagnostic report

📦 Requirements

Minecraft: 1.21.1 / 26.1.2 / 26.2 / 26.3
Mod Loader: NeoForge
Recipe Viewer: At least one supported JEI, REI or EMI version
Environment: Client & Server

Install the matching Recipe Item Sync JAR on both the server and clients.

The original datapacks can remain server-side. Custom textures, models and translations still require their corresponding client resource packs.

Important: Recipe Item Sync does not create new registered items or replace the original datapack’s functionality. Highly customized crafting systems may not always be representable in a standard recipe viewer.
