Talks

React: Lifting state up is killing your app

Have you heard about “lifting state up”? Is it possible that one of the 12 main concepts listed in React official documentation might lead to poor performance? Can well-known best practices lie? We're going to build a simple data grid with React. We will see which pitfalls it hides and when O(1) can still be slow.

React: Form management in 2020

Logging made right or a long journey to the standard CLS API

How do you do logging in your applications? How do you analyze your logs later? In this session, we're going to talk about trace IDs, why they are important. We'll overview the challenges we face with the context management in asynchronous environments. We'll cover how CLS (continuation-local storage) can help us with that and its evolution from the userland library to the standard API which just recently landed in master.

Strict mode in TypeScript or help your compiler help you

TypeScript compiler has over 90 compiler options. 7 of them are known as strict. 1 option to rule them all. We will overview each one of the 7, examine what they do in theory and how it applies to real-world applications. We will go over what covariance/contravariance is, how it applies to TypeScript and why null is its worst enemy.

You can’t perform that action at this time.
