Vue ApexGantt

Installation

npm install vue-apexgantt apexgantt
# or
yarn add vue-apexgantt apexgantt
# or
pnpm add vue-apexgantt apexgantt

License Setup

If you have a commercial license, set it once at app initialization before rendering any charts:

import { setApexGanttLicense } from 'vue-apexgantt';

// call this at the top of your app
setApexGanttLicense('your-license-key-here');

Example with Vue app entry point:

// main.ts
import { createApp } from 'vue';
import { setApexGanttLicense } from 'vue-apexgantt';
import App from './App.vue';

// set license before rendering
setApexGanttLicense('your-license-key-here');

createApp(App).mount('#app');

Quick Start

<template>
  <ApexGanttChart
    :tasks="tasks"
    view-mode="week"
    height="500px"
  />
</template>

<script setup lang="ts">
import { ref } from 'vue';
import { ApexGanttChart } from 'vue-apexgantt';
import type { TaskInput } from 'vue-apexgantt';

const tasks = ref<TaskInput[]>([
  {
    id: 'task-1',
    name: 'Project Planning',
    startTime: '01-01-2024',
    endTime: '01-08-2024',
    progress: 75,
  },
  {
    id: 'task-2',
    name: 'Development',
    startTime: '01-09-2024',
    endTime: '01-20-2024',
    progress: 40,
    dependency: 'task-1',
  },
]);
</script>

Event Handling Example

<template>
  <ApexGanttChart
    :tasks="tasks"
    @task-dragged="handleTaskDragged"
    @task-resized="handleTaskResized"
    @task-update-success="handleTaskUpdateSuccess"
  />
</template>

<script setup lang="ts">
import type { 
  TaskDraggedEventDetail,
  TaskResizedEventDetail,
  TaskUpdateSuccessEventDetail 
} from 'vue-apexgantt';

const handleTaskDragged = (detail: TaskDraggedEventDetail) => {
  console.log('Task dragged:', detail);
  // save to backend, etc.
};

const handleTaskResized = (detail: TaskResizedEventDetail) => {
  console.log('Task resized:', detail);
};

const handleTaskUpdateSuccess = (detail: TaskUpdateSuccessEventDetail) => {
  console.log('Task updated:', detail);
};
</script>

Template Ref Methods

Access chart methods using template ref:

<template>
  <ApexGanttChart
    ref="ganttRef"
    :tasks="tasks"
  />
  
  <button @click="handleZoomIn">Zoom In</button>
  <button @click="handleZoomOut">Zoom Out</button>
</template>

<script setup lang="ts">
import { ref } from 'vue';
import { ApexGanttChart } from 'vue-apexgantt';

const ganttRef = ref<InstanceType<typeof ApexGanttChart> | null>(null);

const handleZoomIn = () => {
  ganttRef.value?.zoomIn();
};

const handleZoomOut = () => {
  ganttRef.value?.zoomOut();
};

// available methods:
// ganttRef.value?.update(options)
// ganttRef.value?.updateTask(taskId, data)
// ganttRef.value?.zoomIn()
// ganttRef.value?.zoomOut()
// ganttRef.value?.destroy()
// ganttRef.value?.getInstance() // get raw ApexGantt instance
</script>

Composables

useGanttData

Parse external data into ApexGantt format:

<script setup lang="ts">
import { ref } from 'vue';
import { ApexGanttChart, useGanttData } from 'vue-apexgantt';
import type { ParsingConfig } from 'vue-apexgantt';

// raw API data
const apiData = ref([
  {
    task_id: 'T1',
    task_name: 'Design Phase',
    start_date: '01-01-2024',
    end_date: '01-15-2024',
    completion: 0.75,
  },
  // ...more tasks
]);

// parsing configuration
const parsingConfig: ParsingConfig = {
  id: 'task_id',
  name: 'task_name',
  startTime: 'start_date',
  endTime: 'end_date',
  progress: {
    key: 'completion',
    transform: (value) => value * 100, // convert to percentage
  },
};

// parse data
const tasks = useGanttData({
  data: apiData,
  parsing: parsingConfig,
});
</script>

<template>
  <ApexGanttChart :tasks="tasks" />
</template>

Nested Objects & Transforms

Use dot notation for nested properties:

const nestedData = ref([
  {
    project: {
      task: { id: 'T1', title: 'Design' },
      dates: { start: '01-01-2024', end: '01-15-2024' },
      status: { completion: 0.75 },
    },
  },
]);

const tasks = useGanttData({
  data: nestedData,
  parsing: {
    id: 'project.task.id',
    name: 'project.task.title',
    startTime: 'project.dates.start',
    endTime: 'project.dates.end',
    progress: {
      key: 'project.status.completion',
      transform: (value) => value * 100,
    },
  },
});
