Node Congress 2024

- Delve into the intricacies of optimizing microservice architecture for achieving high performance and resilience.- Explore the challenges related to performance bottlenecks and resilience in microservices-based systems.- Deep dive into the strategies for enhancing performance, such as efficient communication protocols, asynchronous messaging, and load balancing, while also discussing techniques for building resilience, including circuit breakers, fault tolerance, and chaos engineering.- Explore relevant tooling and technologies, such as service mesh and container orchestration, and offer insightful case studies and lessons learned from real-world implementations.- Emphasize the importance of continuous improvement and adaptation in microservices environments, alongside reflections on the future trajectory of microservices architecture.

Why bother to optimize images? Images often account for most of the downloaded bytes on a web page. As a result, optimizing images can frequently yield of the performance improvements for your website.

React Advanced

React Advanced Conference 2023

Ivan’s first attempts at performance debugging were chaotic. He would see a slow interaction, try a random optimization, see that it didn't help, and keep trying other optimizations until he found the right one (or gave up). Back then, Ivan didn’t know how to use performance devtools well. He would do a recording in Chrome DevTools or React Profiler, poke around it, try clicking random things, and then close it in frustration a few minutes later. Now, Ivan knows exactly where and what to look for. And in this workshop, Ivan will teach you that too. Here’s how this is going to work. We’ll take a slow app → debug it (using tools like Chrome DevTools, React Profiler, and why-did-you-render) → pinpoint the bottleneck → and then repeat, several times more. We won’t talk about the solutions (in 90% of the cases, it’s just the ol’ regular useMemo() or memo()). But we’ll talk about everything that comes before – and learn how to analyze any React performance problem, step by step. (Note: This workshop is best suited for engineers who are already familiar with how useMemo() and memo() work – but want to get better at using the performance tools around React. Also, we’ll be covering interaction performance, not load speed, so you won’t hear a word about Lighthouse 🤐)

Vue.js London 2023

You've just landed on a web page and you try to click a certain element, but just before you do, an ad loads on top of it and you end up clicking that thing instead. That…that’s a layout shift. Everyone, developers and users alike, know that layout shifts are bad. And the later they happen, the more disruptive they are to users. In this workshop we're going to look into how web fonts cause layout shifts and explore a few strategies of loading web fonts without causing big layout shifts.
