Playground ​

Write helix authoring code on the left; the compiled datapack - the exact .mcfunction and JSON files helix emits - appears on the right, recompiled as you type. It's the real compiler running in your browser (no server), so what you see here is what you'd get from dp.writeDatapack(...). Change the target version to watch the output adapt (folder names, pack format, command grammar).

See the Concepts guide for the building blocks, or the API reference for everything in scope.
