Quick Start

import { Gantt, type GanttDataAdapter } from "@polycyphers/gantt";

const adapter: GanttDataAdapter = {
  loadSchedule: async () => fetch("/api/schedule/1").then((r) => r.json()),
  updateTask: async (taskId, patch) => fetch(`/api/task/${taskId}`, { method: "PUT", body: JSON.stringify(patch) }),
  // …
};
