Write TypeScript, get a datapack

Here's a small function that greets every player and hands them some diamonds. The tabs below are the actual files the compiler produced from it:

import { Datapack, v26_2, Selector, Item } from "helix";

const dp = new Datapack("welcome", v26_2);

dp.createFunction("greet").build((ctx) => {
  const players = Selector.allPlayers();
  ctx.tellraw(players, "Welcome to the server!");
  ctx.playerGive(players, Item.DIAMOND, 3);
});
