Installation

This is a trial package with limited functionality.

Why Use npm Aliasing?

Trial packages use npm aliasing to install @bryntum/gantt-trial under the @bryntum/gantt name. This approach provides a seamless upgrade path - when you purchase a license, you only need to update the alias in package.json without changing any application code.

Install using npm:

npm install @bryntum/gantt@npm:@bryntum/gantt-trial@latest

Or using yarn:

yarn add @bryntum/gantt@npm:@bryntum/gantt-trial@latest

Alternatively, add to package.json dependencies:

"dependencies": {
  "@bryntum/gantt": "npm:@bryntum/gantt-trial@latest"
}

Visit our npm repository guide to learn more about installation and migrating from trial to licensed packages.

Using an AI agent?

The fastest path for an AI assistant to write working Bryntum Gantt code:

1. MCP server. Configure your agent with the Bryntum MCP server for grounded, version-correct answers: setup guide.
2. Agent skills. Install the Bryntum skill for Claude Code, Cursor, or Codex — it bundles the conventions below.

Common trial-package pitfalls for agents:

• Stale training data. Bryntum ships breaking changes; do not trust API shapes you remember. Check https://bryntum.com/products/gantt/docs first.
• You are on the trial. The package is installed as @bryntum/gantt-trial but aliased to @bryntum/gantt — import paths must use the aliased name (@bryntum/gantt). To upgrade to a licensed package, change the alias to "npm:@bryntum/gantt@latest"; do not rewrite imports.
• Trial bundles are not minified and contain a watermark; that is expected, not a bug.
• CSS. Import FontAwesome, gantt.css (structural), and a theme.
• Framework wrappers (@bryntum/gantt-react, -angular, -vue-3) require the core @bryntum/gantt package; installing only the wrapper fails at runtime.
• TypeScript types are bundled in *.d.ts next to each entry point; do not hand-roll interfaces.

Quick Start

Vanilla JavaScript

import { Gantt } from '@bryntum/gantt';
import './style.css';

const gantt = new Gantt({
    appendTo  : 'app',
    startDate : new Date(2022, 0, 1),
    endDate   : new Date(2022, 0, 10),
    columns   : [
        { type : 'name', width : 160 }
    ],
    project : {

        // Automatically introduces a `startnoearlier` constraint for tasks that (a) have no predecessors,
        // (b) do not use constraints and (c) aren't `manuallyScheduled`
        autoSetConstraints : true,
        tasks              : [
            {
                id       : 1,
                name     : 'Documentation Project',
                expanded : true,

                        ]

                            { id : 8, name : 'Write tutorials', startDate : '2026-01-10', endDate : '2026-01-16' },
                            { id : 9, name : 'Create examples', startDate : '2026-01-12', endDate : '2026-01-18' }
                        ]
                    },
                    {
                        id       : 5,
                        name     : 'Review & Release',
                        expanded : true,
                        children : [
                            { id : 10, name : 'Team review', startDate : '2026-01-18', endDate : '2026-01-20' },
                            { id : 11, name : 'Final approval', startDate : '2026-01-20', endDate : '2026-01-21' },
                            { id : 12, name : 'Public release', startDate : '2026-01-22', endDate : '2026-01-22' }
                        ]
                    }
                ]
            }

        dependencies : [

            { fromTask : 8, toTask : 9 },
            { fromTask : 9, toTask : 10 },
            { fromTask : 10, toTask : 11 },
            { fromTask : 11, toTask : 12 }
        ]
    }
