Bolero (http://fsbolero.io) is a functional, reactive web development library for F# developers targeting WebAssembly via Blazor. Next to building on a familiar Model-View-Update (MVU) architecture, Bolero also integrates a number of power features from WebSharper (http://websharper.com) to enable ultra-efficient, full-stack F# web applications. By plugging into the ever-growing Blazor ecosystem, you will enjoy developing most of your code base without JavaScript, and discover a new and promising alternative to building performant web applications. Come to this talk and learn everything you need to know about developing Bolero applications, and jumpstart your productivity with skills that will leave any Blazor developer impressed.

When it comes to developers blogging, expectations are high and many find that it’s a worthwhile effort to develop simple scripts, tools and even full engines to enhance and support blogging about their favorite language. In this hands-on session, you will implement your own blog engine from scratch in just a few hundred lines of F# code using WebSharper, and use its static file generation capabilities to generate blog pages that you can deploy directly into GitHub Pages or host in any web server. The resulting blog can easily be styled using WebSharper’s powerful templating capabilities, and even automated to rebuild when you commit new content or blog articles in your blog repository. You will also learn about adding dynamic functionality to your generated blog pages, or even turning your blog engine to a hosted solution that provides further capabilities as well. No more searching for blog engines with the right features, code what you need and enjoy!

Having worked in mobile app development for years I can say one thing for sure: creating a mobile application is hard. Creating a cross-platform mobile application is even harder. Which is why I was interested when Fabulous came out.

Fabulous is a new cross-platform mobile library which mixes Xamarin-Forms and Elm Architecture. The Elm language and architecture were not new to me. I had been using it for a year and it had left a positive impression on me. So, it was only natural that Fabulous attracted my attention. First time I tried it after it got launched, I wasn’t impressed by its performance, but recently I gave it another try for a production application and I was amazed. I was able to create a complete app.

In this talk, I will tell you why I choose Fabulous instead of other Cross Platform mobile development options for my app. I will walk you through all the mobile-specific changes I made to get Fabulous working in a performant way for iOS and Android and explain to you how you can use in combination with third-party plugins.

People always talked about beautiful apps, be it web or mobile. Create a crazy number of frameworks to make your frontend work as fast as possible. But they mostly forget about the backend part, called the server-side application.

TypeLevel stack provides wonderful sets of purely functional libraries to write backend code. A backend can be a simple monolith server or micro-service styled multi-server application. TypeLevel stack allows you to write your server code with less error and more confidence. TypeLevel stack has libraries for almost everything from doing Http to database access.

In this talk, I will tell you why anyone should TypeLevel stack to build a backend application. I will also share little bit controversial opinionated way to arrange things. It will also showcase how composability of functional programming helps to write the scalable application.
