🗣️ Talks
➡️ Anastasiia Zlenko – How Property-Based Testing Helps Maximize Test Coverage at Grammarly
Writing efficient unit tests is essential for critical software components. But how do we ensure that our tests are thorough enough to cover a huge variety of typical inputs and most edge cases? I'll introduce you to the concept of property-based testing and share how we benefited from using it at Grammarly.
➡️ Michał Trojanowski – Securing Single Page Applications Using The Token Handler Pattern
Single Page Applications appear simple at first sight. Web developers provide a superb user experience, and it is also relatively easy to implement token-based security in the browser. Yet this is against current best practices for browser-based apps, and security concerns can become a blocking issue. It is instead recommended to implement a Backend for Frontend (BFF), to reduce browser threats. Yet this often results in the adoption of website technologies to issue secure cookies, which can work against other web architecture goals. In this talk, I will show how a separation of web and API concerns can give you the best choices. In the talk, I will present the Token Handler Pattern — Curity's variation of the Backend For Frontend approach. I will show the open-source projects we created that facilitate the implementation of the pattern.
➡️ Matthias Geisler – KotlinJS - Something You Want to Use for Web?
The talk will give a quick intro into Kotlin for Web via KotlinJS. It will speak about the ups and downs in comparison to Typescript. It will go into the idea of Kotlin Fullstack and what this can mean for your codebase. And of course it will ask if it is something you want to use in production.➡️ Open Mic Lightning Talks – every attendee is welcome to speak (<5min)
