Salvatore Cordiano, a full stack web developer with over six years of experience, recently gave an innovative presentation at the Chatbots Milano Conference using reveal.js and PubNub to create an interactive experience. By developing a plugin for the popular HTML presentation framework reveal.js, he enabled audience interaction through a Telegram bot, allowing control of the slides in real time. His approach leverages the PubNub publish-subscribe API to remotely control presentations, which can be initiated from a webpage, Telegram bot, or mobile app. Salvatore shared insights into setting up reveal.js with Node.js and Grunt, installing the plugin, and configuring it with PubNub keys to enhance presentations with dynamic and engaging features.
