How can I dynamically adjust resource availability and event details in FullCalendar for different views in ReactJS?

Below is one way to approach this. The idea is to use your component’s state (in this case, currentView) to choose which resources and events to pass to FullCalendar. Then, you can pre-process or aggregate events as needed per view. Here’s an annotated version showing how you might implement the three points:

---

1. Dynamic Resource Loading

Maintain a mapping object (like your resourcesByView) and update your state when the view changes. This allows FullCalendar to load different resource definitions based on the active view.

2. Event Aggregation in Week View

For the week view, you can pre-process your events (or keep a separate array) to aggregate detailed events into summaries. In the example below the eventsByView object contains an aggregated event for the week.

3. Conditional Resource Display

Similarly, by having separate resource definitions for each view (e.g. a single “All Rooms” resource for the month view), you conditionally display only high-level availability.

Below is the updated code with inline comments for clarity:

import FullCalendar from '@fullcalendar/react';
import resourceTimelinePlugin from '@fullcalendar/resource-timeline';
import interactionPlugin from '@fullcalendar/interaction';
import { useState } from 'react';

const MyResourceCalendar = () => {
  // Track the active FullCalendar view.
  const [currentView, setCurrentView] = useState('resourceTimelineDay');

  // Define resources for each view.
  const resourcesByView = {
    resourceTimelineDay: [
      { id: '1', title: 'Room A' },
      { id: '2', title: 'Room B' },
      { id: '3', title: 'Room C' },
    ],
    resourceTimelineWeek: [
      { id: '1', title: 'Room A' },
      { id: '2', title: 'Room B' },
    ],
    resourceTimelineMonth: [
      { id: '1', title: 'All Rooms' },
    ],
  };

  // Define events for each view. For week view, the events are aggregated summaries.
  const eventsByView = {
    resourceTimelineDay: [
      { title: 'Meeting', start: '2024-06-01T09:00:00', end: '2024-06-01T10:00:00', resourceId: '1' },
      { title: 'Conference', start: '2024-06-01T12:00:00', end: '2024-06-01T14:00:00', resourceId: '2' },
      // You can extend this by dynamically fetching or computing detailed events.
    ],
    resourceTimelineWeek: [
      // Example aggregated event for the week view.
      { title: 'Team Week Event', start: '2024-06-03', end: '2024-06-07', resourceId: '1' },
      // If additional events need aggregation, do so before setting them here.
    ],
    resourceTimelineMonth: [
      // High-level resource availability (e.g., overall “Available” or “Booked”)
      { title: 'Available', start: '2024-06-01', end: '2024-06-30', resourceId: '1' },
    ],
  };

  return (
    <FullCalendar
      plugins={[resourceTimelinePlugin, interactionPlugin]}
      // Change the initial view based on state
      initialView={currentView}
      // Define custom view buttons if desired
      views={{
        resourceTimelineDay: { buttonText: 'Day' },
        resourceTimelineWeek: { buttonText: 'Week' },
        resourceTimelineMonth: { buttonText: 'Month' },
      }}
      // Pass the resources and events for the current view
      resources={resourcesByView[currentView]}
      events={eventsByView[currentView]}
      // When the view changes, update the currentView state accordingly.
      datesSet={(dateInfo) => setCurrentView(dateInfo.view.type)}
    />
  );
};

export default MyResourceCalendar;

Explanation

• Dynamic Resource Loading:
  The resourcesByView[currentView] expression selects the correct list of resources based on the currentView state. This allows you to change the resources dynamically when the user switches views.

• Event Aggregation in Week View:
  In the week view mapping (resourceTimelineWeek), you can define events to represent an aggregated summary (for example, by combining several detailed events into one). In a real-world scenario, you might perform this aggregation by processing your raw events data before assigning it to the eventsByView.

• Conditional Resource Display:
  For the month view, you restrict the displayed resources to a high-level summary (e.g., using a single resource labeled "All Rooms"). Again, this is configured in your mapping object.

By structuring your components this way, you keep the code organized and maintainable, ensuring that your FullCalendar view is dynamically adjusted based on the selected view type.
