Code Examples

Creating a basic Gantt chart:

const tasks = [
  {
    id: 'Task 1',
    name: 'Redesign website',
    start: '2023-01-01',
    end: '2023-01-10',
    progress: 20
  },
  // Add more tasks here
];

const gantt = new Gantt("#gantt", tasks);

Adding task click event:

gantt.on('task_click', (task) => {
  console.log(`Clicked task: ${task.name}`);
});

Updating task progress:

gantt.change_progress('Task 1', 50);

Getting Started

1. Include the Frappe Gantt CSS and JS files in your HTML:

<link rel="stylesheet" href="https://cdn.jsdelivr.net/npm/frappe-gantt/dist/frappe-gantt.css">
<script src="https://cdn.jsdelivr.net/npm/frappe-gantt/dist/frappe-gantt.min.js"></script>

2. Create a container element in your HTML:

<div id="gantt"></div>

3. Initialize the Gantt chart in your JavaScript:

const tasks = [
  {
    id: 'Task 1',
    name: 'Project Kickoff',
    start: '2023-05-01',
    end: '2023-05-05',
    progress: 0
  },
  {
    id: 'Task 2',
    name: 'Design Phase',
    start: '2023-05-06',
    end: '2023-05-15',
    progress: 0,
    dependencies: 'Task 1'
  }
];

const gantt = new Gantt("#gantt", tasks, {
  view_modes: ['Quarter Day', 'Half Day', 'Day', 'Week', 'Month'],
  bar_height: 40,
  bar_corner_radius: 3,
  arrow_curve: 5,
  padding: 18
});

This will create a basic Gantt chart with two tasks, including a dependency between them. You can customize the appearance and behavior further using the available options and methods provided by the library.
