Build Interactive Timelines with Gantt Chart Light Library

3. React integration

• Install and wrap in a component that mounts the chart once.

 ffON2NH02oMAcqyoh2UU MQCbz04ET5EljRmK3YpQ CPXAhl7VTkj2dHDyAYAf” data-copycode=“true” role=“button” aria-label=“Copy Code”>Copy CodeCopied
import React, { useRef, useEffect } from ‘react’;
import { Gantt } from ‘gantt-chart-light’;
import ‘gantt-chart-light/dist/gantt-chart-light.css’;

export default function GanttChart({ tasks, options }) {
  const ref = useRef(null);
  useEffect(() => {
    const gantt = new Gantt(ref.current, options);
    gantt.loadTasks(tasks);
    return () => gantt.destroy();
  }, [tasks, options]);
  return <div ref={ref} />;
}

• Keep tasks stable (useMemo) to avoid unnecessary re-renders. Use event handlers from the library to sync edits back to state.

4. Vue integration

• Mount in mounted() hook and destroy in beforeUnmount(). Use v-bind to pass props and emit events on task changes.

import { Gantt } from ‘gantt-chart-light’;
export default {
  props: [‘tasks’,‘options’],
  mounted() {
    this.gantt = new Gantt(this.\(el</span><span class="token" style="color: rgb(57, 58, 52);">,</span><span> </span><span class="token" style="color: rgb(0, 0, 255);">this</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span>options</span><span class="token" style="color: rgb(57, 58, 52);">)</span><span class="token" style="color: rgb(57, 58, 52);">;</span><span> </span><span>    </span><span class="token" style="color: rgb(0, 0, 255);">this</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span>gantt</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span class="token" style="color: rgb(57, 58, 52);">loadTasks</span><span class="token" style="color: rgb(57, 58, 52);">(</span><span class="token" style="color: rgb(0, 0, 255);">this</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span>tasks</span><span class="token" style="color: rgb(57, 58, 52);">)</span><span class="token" style="color: rgb(57, 58, 52);">;</span><span> </span><span>    </span><span class="token" style="color: rgb(0, 0, 255);">this</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span>gantt</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span class="token" style="color: rgb(57, 58, 52);">on</span><span class="token" style="color: rgb(57, 58, 52);">(</span><span class="token" style="color: rgb(163, 21, 21);">'taskChange'</span><span class="token" style="color: rgb(57, 58, 52);">,</span><span> </span><span class="token parameter">task</span><span> </span><span class="token" style="color: rgb(57, 58, 52);">=></span><span> </span><span class="token" style="color: rgb(0, 0, 255);">this</span><span class="token" style="color: rgb(57, 58, 52);">.</span><span class="token" style="color: rgb(57, 58, 52);">\)emit(‘update:task’, task));
  },
  beforeUnmount() { this.gantt.destroy(); }
}

5. Svelte integration

• Initialize in onMount, use store or props for tasks, and cleanup on destroy. Bind events to dispatch updates.

6. Styling & themes

• Override CSS variables or import a theme file if provided. Prefer class-based overrides for safe upgrades.
• Use container size and responsive options to let the chart adapt; set max-height with overflow for large charts.

7. Data model & syncing

• Use a normalized tasks array: id, name, start, end/duration, progress, depends, assignee, custom fields.
• On in-chart edits, listen to events (taskAdd, taskChange, taskDelete) and update your app state and backend via REST/GraphQL.
• Debounce bulk syncs and send diffs instead of full arrays for performance.

8. Performance tips

• Virtualize long task lists in the grid if supported.
• Use incremental updates (add/update/delete) rather than reloading all tasks.
• Limit DOM-heavy features (complex templates, many custom element nodes).
• Lazy-load heavy dependencies and charts for offscreen routes.

9. Accessibility & keyboard

• Ensure role and aria attributes are present or add them in a wrapper.
• Provide keyboard navigation, focus outlines, and high-contrast theme options.
