Building an interactive live reaction app with Next.js and Momento🎯

The blog post describes the process of building an interactive live reaction app using Next.js and Momento, designed to enhance audience engagement during online presentations. Inspired by Michael Liendo's use of WebSockets and Apple Keynote for real-time audience interaction, the author develops a solution compatible with Google Slides, which is free and offers collaborative features. The app allows users to dynamically display presentations and gather real-time reactions through emojis and comments via a QR code and a mobile-optimized interface. To simplify deployment and architecture, the app leverages Momento for WebSocket management, avoiding complex cloud infrastructure and ensuring ease of hosting on platforms like Vercel or AWS Amplify. The app also offers fun statistics post-presentation by using a sorted set to display leaderboards based on audience reactions. The project aims to make presentations more engaging and memorable, providing a cost-effective solution for real-time audience feedback, with incentives for future enhancements.
