Presentation 1: 18:00 : Michał Michalczuk – "How to model your crazy data in TypeScript" (EN)

Description: TypeScript type system give us great possibilities to model the data and behavior of our application. No matter if it is a client app or a server app in Node.js. It’s getting more and more popular, but most of the time … we’re not using its full power. During my presentation, I will show you some tips how to deal with strange types cases, don’t make a type-mess and unleash the full language potential.

Our data models can be crazy. Sometimes you take a quick look and you already see that if-else to handle it properly. But if you use TypeScript you can handle most of it on the compilation level. I will show you how I’m dealing with strange types cases, how to avoid type-mess in your app, properly use algebraic types and how to benefit from structural type system.

Presentation 2: 19:00 : Guðmundur Hreiðarsson - "Unbreakable APIs" (EN)

Description: We’ve all broken things – despite our good intentions, we are only human, and make mistakes. A very common and hard to catch mistake is breaking the technical contracts we’ve defined: Breaking our APIs. An innocent refactoring might bring everything down, despite our code building fine and tests being green.
Fucking up should be hard, not easy. And guarding against fucking up should be easy, or we wont do it. We shouldn’t have to write manual unit tests for every piece of mapping code we write to ensure we don’t break things.
Luckily, when it comes to APIs, we have a formal way for describing APIs using Swagger/OpenAPI specifications. Using those we can automate the process of comparing API contracts. I’ll lead you through the wonders of playing with API specs – with which you stop breaking APIs once and for all.
