DHTMLX React Scheduler: Create Customizable Scheduling Interfaces with React

When building scheduling features in a React app, developers often run into limitations with basic calendar libraries, including poor performance, limited flexibility, or unimpressive feature set. DHTMLX React Scheduler solves these issues by providing a fully-featured scheduling component designed for React.

With native props, state-friendly updates, full access to the Scheduler API, and seamless integration with Redux and Material UI, it allows web developers to focus on building powerful applications instead of reinventing scheduling logic.

Let’s dive into the main feature set of DHTMLX React Scheduler and learn how to get started quickly while building scheduling calendars in React.

React Scheduler Key Features

📂Declarative Data Handling

DHTMLX React Scheduler is built to feel natural for React developers and simplify data management by embracing a declarative approach. You can pass arrays of events, calendar views, markers, and other configuration elements directly as props. This allows your scheduler to automatically render and update based on the data you provide, keeping your React code clean and in sync with your app state.

⚛️Full Control Through React Components

You can replace default elements, including a lightbox editor or event templates, with custom React components by updating a property with no manual DOM manipulations.

🗓️Built-in Basic and Advanced Calendar Views

The Scheduler component comes with a rich set of customizable calendar views to cover a wide range of scheduling scenarios. Out of the box, you can switch between Day, Week, Month, Year, Agenda, and Map views to display events in the most convenient format.

For more complex scenarios, DHTMLX Scheduler offers advanced views, including Grig, Week Agenda, Timeline, and Units. The Timeline view displays events arranged horizontally across separate timelines, making it perfect for visualizing workloads by people, rooms, or equipment. The Units view organizes resources along the X-axis with a timescale on the Y-axis. This setup makes it easy to build daily planners or staff timetables, since any property can group events.

🔁Recurring Events

The React Scheduler component comes with built-in support for recurring events. You can define repeat patterns, e.g., on a daily, weekly, monthly, and yearly basis, and the component will automatically generate and update all instances, thus saving end-users from managing complicated recurrence logic themselves.

🖱️Rich Drag-and-Drop Behavior

DHTMLX Scheduler provides smooth drag-and-drop support for event management. Users can create new events by dragging elements from external DHTMLX components into the calendar. Events can also be moved between multiple schedulers on the same page. Developers have full control over enabling or restricting drag-in/out actions, making scheduling more intuitive.

🚫Avoiding Overlapping Events

You can set a limit on the number of events allowed per slot. Thus, for example, if a time interval is already booked, the React Scheduler can deny the creation of a second event at that time. By applying a simple configuration, DHTMLX Scheduler ensures data integrity and provides end-users with a clear, conflict-free scheduling experience.

⚡️Dynamic Loading

When working with large event collections, loading all data at once can slow down your app. DHTMLX React Scheduler solves this with dynamic loading, which fetches only the data required for the current visible area of the calendar.

You can define how much data should be loaded at a time (by day, week, month, or year). For example, in a Week mode, the Scheduler will only request events for the current week, fetching additional weeks on demand as users navigate.

For a better user experience, you can also enable a loading spinner, ensuring users know when new data is being fetched.

🎨Flexible Theming and MUI Compatibility

DHTMLX Scheduler comes with built-in themes and supports runtime theming using the skin prop. Styling is simplified through CSS variables. Therefore, you can adjust colors, fonts, and other UI elements consistently across your app. In addition, seamless integration with Material UI ensures your scheduler blends perfectly into modern React interfaces.

How to Get Started

DHTMLX React Scheduler is available as an NPM package and requires React 18 and newer. Under the hood, it initializes a standard DHTMLX Scheduler instance but translates React props.

Here is an example of importing and rendering the Scheduler:

import React, { useEffect, useRef, useState } from 'react';
import ReactScheduler, { Event, SchedulerConfig, SchedulerTemplates } from "@dhx/react-scheduler";
import "@dhx/react-scheduler/dist/react-scheduler.css";
import "./styles.css";
import { initialData } from "./DemoData";


export default function SchedulerTemplatesDemo() {
  const config: SchedulerConfig = {
    first_hour: 8,
    last_hour: 20,
    time_step: 15
  };

  const templates: SchedulerTemplates = {
    event_class: (start, end, event) => {
      return event.classname || '' ;
    }
  };



  return (
    <div style=height: '100%', display: 'flex', flexDirection: 'column'>
      <ReactScheduler
        events={initialData.events}
        date={new Date("2025-08-15T00:00:00Z")}
        view={"week"}
        templates={templates}
        config={config}
      />
    </div>
  );
};

Summing up, DHTMLX React Scheduler is a powerful and developer-friendly solution for building advanced scheduling interfaces in React. With features like multiple calendar views, recurring events, and drag-and-drop support, it streamlines event management. Whether you’re creating booking systems or resource planners, React Scheduler helps you deliver a smooth and professional scheduling experience.
