Frontend Testing Reinvented - Gert Hengeveld

Gert is a staff software engineer at Chromatic, a US-based startup founded by Storybook maintainers. He works remotely from his home in Amersfoort with a globally distributed team of experts in UI engineering. When not at work or hanging out with the family, he likes cycling, (water)skiing, and the occasional video game.

Imagine writing a complex function without unit tests. You would have to verify every scenario manually, over and over again. Cumbersome, but that's how most teams build user interfaces. Imagine if you could build UIs and test UIs in the same place. If your components included expectations for how they were supposed to behave, you'd know the instant they broke. Storybook provides an organised approach to building UIs. You document a component's use-cases as stories, which are then rendered in isolation. Stories are like tests, but for UI. Storybook interaction testing allows you to script interactions and check expectations in the story itself. That allows you to run and debug UI tests in the same environment UI components are developed for: your browser.

Optimising Data Fetching - Medhat Dawoud

Medhat is a Senior Frontend Engineer and a Google Developer Expert in Web Technologies with extended experience in several web technologies, through his writings on his blog, online video courses, and talks he likes to share learnings, tips to write cleaner/reusable code, and useful DevTools, also he likes to speak about web performance and how to ship a fast and accessible web application to everyone

Several reasons might cause poor performance of your web application, fetching data from a remote server could be a big one of them, in this talk I'm going to take you through the several reasons that make fetching data performance not the best and how to fix them easily with examples
