One of the strategies being adopted by RoR or Java software developers in adopting Elixir is they have not yet adapted themselves to unlearn the OOP in developing the web systems. This has caused OOP concepts to creep into full fledged Elixir systems. This presentation seeks to highlight these subtle points that need to be avoided to make the code more FP and less OOP.

At Helpshift, we face managing complexity of these side effects which touch 10s of different systems. Each side effect poses a failure scenario which can lead to it's own business decision. Compounded failures pose even more complexity. To add to the problems we extending the codebase to add new business logic regularly.

I will present a solution which is a combination of Clojure and FP following techniques. We will also discuss how ideas when combined together can create an elegant solution,

1. Data - Side effects definition as data

2. Almost no syntax - Minimal definition

3. Many functions for one DS - Multiple execution and failure recovery modes for side effects

Erlang has been in production for more than 30 years and a highly battle-tested robust system, which is being used by everybody including Telecom systems that provides 99.99% uptime. Elixir has been built on top of Erlang overcoming the shortcomings of the language and also using meta-programming, it has opened a new paradigm of looking at the language itself. I want to show what Elixir is to the audience and minute nuances that every experienced or inexperienced developer should be aware of before jumping into the magical erlang and elixir world.

Phoenix LiveView provides ability to build web application without any custom javascript.
You can write all the code on Backend server and the connection is alive and stateful.

In this workshop, you will build Tetris App in Elixir and Phoenix LiveView. The aim of this workshop is give more hands-on Elixir experience and cover various functions and syntax.

WebAssembly is one of the new technologies around the block that has vast areas still to be explored. I'd like to give a talk explaining what the WebAssembly is, what are the possibilities that you can cover with the help of WebAssembly, how does Elixir and BEAM VM fit into the equation and how to interoperate between Elixir and WebAssembly.
