Building end-to-end encrypted applications is exciting, but also intimidating. This talk is designed to lower the entry barrier, offering a clear roadmap for integrating end-to-end encryption in collaborative, real-time applications.We begin by unveiling a simple design with one shared encryption key, promptly addressing its inherent challenges. Progressively, we delve into tools like Opaque, Secsync and CRDTs to tackle the challenges we identified and enhance our application with the goal of offering a seamless user experience without compromising on security.Each segment of the talk starts with an accessible overview before diving into practical, code-based examples. This approach not only demystifies the intimidating theory and empowers attendees with the tools and knowledge to apply these principles effectively in their projects.

Conditional rendering issues in JSX, forwardRef, serveral ways to create refs, render props (yeah they still exist), higher-order components (do they still exist?), act, non-extendable classes, SuspenseList (well, maybe in 10 years), React.FC and of course our good old friend useEffect. All these weird things are part of our favourite library (not a framework™) and yet we still use and love it. Why actually? Let's talk about. Disclaimer: This is not a very serious talk, mostly …
