Getting started with Fable - F# to JS compiler


Javascript has conquered the world – you can use it in the browser, on the server, to write mobile apps, or on the desktop with Electron. During the workshop I’ll introduce Fable - an open source compiler that brings all 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. 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 such as webpack or babel. Also, Fable is not only for front-end web apps, it integrates with the whole JS ecosystem including server-side node apps, desktop with Github Electron and mobile with Fuse or React Native. During the workshop participants will learn how to use Fable with different types of applications, including client side web applications, server APIs, and mobile applications.
