The MVC pattern has been one of the most important architectural patterns for server-side web development - it has been implemented and popularized by frameworks like Ruby On Rail or ASP.NET MVC. However, this pattern was traditionally coupled with object-oriented programming. In the talk, I will show how to reinvent MVC pattern, and structure your web application in a functional language - F#.

The talk will cover some brief introduction to F# - modern functional programming language running on .Net platform, show how to model MVC layers using functional composition, and at the end show some examples of applying MVC pattern with Saturn - opinionated, web development framework for F# which implements the server-side, functional MVC pattern

Javascript has conquered the world - developers can use it in the browser, on the server, to write mobile apps, on the desktop with Electron, and even to create serverless services. Like the language or not, the truth is JS developers have built an incredible ecosystem with libraries and tools to do almost anything. During the talk I'll show how to bring the power of F# - the functional paradigm, static typing with type inference, pattern matching, and more modern language features - to this huge and rich JS world using Fable - F# to JS compiler. Fable doesn't add any runtime overhead and generates clean JS code in conformance with new ES6 patterns, like modules or iterables, making it compatible with modern development tools, including Github Electron or React Native to let you develop not only web, but also cross platform desktop and mobile apps. I'll demonstrate how to create different types of JS applications using F# - from React-based frontend application, through mobile app using React Native to serverless services.
