ApexGantt AI Skill

AI coding skill for building ApexGantt timeline / Gantt charts. Works with Claude Code, Cursor, GitHub Copilot, and any AI coding assistant that can read project context.

Separate skill — one of the ApexCharts ecosystem skills. This is the dedicated skill for ApexGantt (apexgantt), shipped as its own apexgantt-skill package and repo — distinct from the core apexcharts-skill and the other product skills. Each product has its own library and skill; use the one that matches yours:

| Product | npm library | Skill package & repo | |---|---|---| | ApexCharts — charts | apexcharts | apexcharts-skill | | ApexGantt — Gantt / timeline · this skill | apexgantt | apexgantt-skill | | ApexTree — hierarchy / org charts | apextree | apextree-skill | | ApexSankey — flow / Sankey | apexsankey | apexsankey-skill | | Apex Grid — data grid | apex-grid | apexgrid-skill |

What This Does

AI models routinely get Gantt-chart code wrong: bad date formats, missing render() calls, listening for events on the wrong target, mutating series in place, treating progress as a fraction. This skill ships structured reference files so the assistant generates correct ApexGantt code on the first try.

Coverage

• Task data format — id, name, startTime, endTime, progress, hierarchy, milestones, baseline
• Dependencies — FS / SS / FF / SF types with lag/lead, critical path
• Lifecycle — render(), update(), updateTask(), destroy(), license key
• Events — full GanttEventMap with CustomEvent.detail shapes
• Selection, drag, resize, inline edit with the right opt-in flags
• Custom toolbar items, columns, parsing for non-standard data shapes
• Framework wrappers: react-apexgantt, vue-apexgantt, ngx-apexgantt

Installation

Claude Code

mkdir -p .claude/skills
cd .claude/skills
git clone https://github.com/apexcharts/apexgantt-skill.git

Cursor / Windsurf

curl -o .cursorrules https://raw.githubusercontent.com/apexcharts/apexgantt-skill/main/.cursorrules

GitHub Copilot

Reference SKILL.md in Copilot Chat: @workspace #file:SKILL.md, or paste the contents of .cursorrules into Copilot's custom instructions.

Generic AI Assistant

Paste the contents of SKILL.md into the system prompt or attach it as context.

As an npm dependency

For tools that build on top of this skill (MCP servers, custom AI agents):

npm install apexgantt-skill

import { skillFile, referencesDir, referencePath } from 'apexgantt-skill';
import { readFile } from 'node:fs/promises';

const skill = await readFile(skillFile, 'utf8');
const deps = await readFile(referencePath('dependencies.md'), 'utf8');
