DHTMLX Event Calendar is a lightweight JavaScript component that provides a developer-friendly way to build feature-packed event calendars with minimum time and effort. There are plenty of configuration and customization options for adjusting this component to specific project requirements. Also, it is possible to transform our Event Calendar into a single scheduling hub by integrating it with widely used calendars, such as Google Calendar. And our team strives to help you achieve this goal.
Today, we are excited to announce the release of the GitHub demo for Google Calendar integration with DHTMLX Event Calendar. This demo can serve as a foundation that you can build upon or tweak to build a custom, production-ready calendar integration.
Benefits of Integrating DHTMLX JavaScript Event Calendar with Google Calendar
Google Calendar is a major player in the scheduling niche, trusted by companies of all scales to handle their day-to-day activities online. So, it is unsurprising that DHTMLX clients may also rely on Google’s ecosystem for daily planning.
That is why we came up with the idea to vividly demonstrate how to integrate Google Calendar with JavaScript event calendar from DHTMLX. From a practical standpoint, this integration can offer multiple benefits:
- Real-time two-way synchronization of events
Any changes in the JavaScript event calendar (adding, editing, or deleting events) are simultaneously reflected in Google Calendar (and vice versa on reload).
- Centralized scheduling experience
End-users don’t need to switch between multiple calendars or apps – all planned activities (personal events, business meetings, etc.) are put together in a unified calendar view, improving collaboration, productivity, and time management.
- Synced data storage
Synced schedules are stored in Google’s cloud, ensuring improved data safety and accessibility.
- Linking with other tools from the Google Ecosystem
Integrating DHTMLX Event Calendar with Google Calendar can also serve as a gateway to connecting with other Google Workspace tools, such as Gmail or Google Meet.
What is interesting in this integration from the developer’s perspective? Let’s find out.
Technical Aspects of JavaScript Event Calendar Integration with Google Calendar
While working on this integration, we took several technical steps to ensure access to the latest JavaScript features and optimizations, secure authentication, smooth data synchronization, and a productive development workflow:
- Modern technology stack (Node + Vite stack)
The integration is built with Node for the backend logic and Vite for fast frontend builds and hot reloading. This modern stack enables the use of the latest JavaScript features and optimizations.
- Secure authentication
Google Calendar API integration provides OAuth 2.0 sign-in with automatic token refresh, handled by Passport-Google-OAuth v3 to ensure secure and reliable access to Google accounts.
- Accurate event mapping
A server-side mapper converts Google Calendar payloads, including recurring and all-day events, into the format expected by DHTMLX Event Calendar.
- Clean architecture
The integration is built with a well-defined, modular architecture, adhering to the separation of concerns (SoC) principle (Express routes → services → mappers). The frontend communicates via a minimalistic REST API. This approach improves the maintainability and scalability of the codebase.
- Smooth developer experience
We used a Monorepo setup with Vite hot-reload for the client-side, the Nodemon CLI utility for the server-side, and a single npm run dev command to start the development server.
In addition to the official release of the integration demo, our team is finalizing the work on a new technical guide that will allow you to repeat this integration path in real-world projects. This guide will include step-by-step instructions on how to set up a JavaScript event calendar and integrate it with Google Calendar. Stay tuned for the upcoming guide release.
