📚 Quick Start

A typical MustJS recipe can be created using the provided utility functions:

compacting(
  itemOutput("minecraft:iron_ingot"),
  [
    itemInput("minecraft:iron_nugget"),
    itemInput("minecraft:iron_nugget"),
    itemInput("minecraft:iron_nugget")
  ],
  "heated"
);

The utility functions can be combined to create more complex recipes while keeping the recipe definitions simple and readable.

🛠️ Designed for KubeJS

MustJS is intended to be used alongside KubeJS and provides helper functions specifically designed to simplify recipe creation.

ServerEvents.recipes(e => {
  // Your recipes here
});

Tip: Start with the Create Functions section if you want to create a new Create recipe, or check the Item and Fluid Utilities sections when you need to construct recipe inputs and outputs.
