Datapack.js

What Datapack.js is

Datapack.js is a free, open-source library for building Minecraft data packs with JavaScript or TypeScript. Its APIs let developers define pack details and assemble content such as advancements, dimensions, enchantments, loot tables, recipes, structures, and biomes. The example builds a data pack with a specified format, name, and description, registers an MCFunction, and provides a .zip output path. Commands may also be written as plain strings.

The library is modular, with a design intended to let third-party tools plug in. Official modules are available to support development, but the commands module is optional; the example imports Effect from that module alongside Datapack and MCFunction from the core package. Installation begins with `npm install @datapackjs/core`. Data packs are folders or .zip files containing a pack.mcmeta file. The project website links to further documentation and examples, and credits Jacob Wennebro as its builder. The public GitHub repository identifies an MIT license.
