Ruby on Rails is a famous “batteries included” framework for the rapid development of web applications. Its full-stack promise comes in a server-oriented, or HTML-over-the-Wire flavor: a server oversees everything from database interactions to your application UI/UX. And whenever there is a server involved, the network and its unpredictability come into play.

With the help of WebAssembly, we can do a radical shift—bring the Rails application right into your browser, and make it local-first!
In my talk, I want to discuss the challenges of making a classic web framework Wasm compatible, the techniques we can use to run server-first applications in the browsers and what are the use cases.
