August Engineering Monthly Round-Up

The OAK’S LAB engineering team rounds up the latest news, insights, and events in the engineering world and shares them with you.

September 6, 2022

At OAK’S LAB, knowledge sharing is part of our DNA. It’s one of the principles that help us build state-of-the-art products from scratch, and it’s the reason why our internal Engineering Newsletter has finally made its way to the pages of the internet.

Our engineers are not afraid to innovate. Every month, we keep an eye on current news, insights, and events related to our industry and relevant to our work, and we share them with each other. The topics range from the newest platforms, extensions, and tools to educational articles, the hottest conferences, inspirational white pages, and more. Now, we want to share them with you. We hope that you too find inspiration in the news, insights, and events below.

This past month at OAK’S LAB we released new products, kicked off new projects, and said goodbye to others. Throughout it all, we gathered insightful articles, explored new platforms, and challenged existing frameworks to improve the way we work. Here’s what we discovered in August 2022.

Engineering News and Insights — a universal platform for webhooks

Webhooks are the backbone of API development. They are universally used, from payment services to receiving SMS messages, but they remain unstandardized API contracts. is a platform that provides a directory of webhook providers and a collection of best practices for providing and consuming webhooks. Created by ngrok.

Modern (and free) web application design patterns

Are you curious about modern application design patterns? What they are? How they are done? is an excellent source for you to discover patterns, tips, and tricks for improving how you architect apps. For a more interactive version, you can explore JavaScript Patterns.

Avoiding useEffect with callback refs

Are you using “refs” effectively and correctly? If you have a basic understanding of refs in React, then this article is a great write-up on ref usage. Key takeaways include: always be careful of what the dependencies are in your useEffect. And don’t forget that “ref” is a function!

Container Queries and :has() have landed on Chrome

Container queries help developers to query the parent selector for its size and styling. But there’s more to it. The developers at Google Chrome go into detail on why this is such a huge release — alongside the :has() feature — for developers everywhere. You can also watch this explanation video for a deeper understanding.

Are 3rd-party resources more harmful than helpful?

Using third-party resources is necessary to track user behavior and even to check if your application is failing. However, they might do harm to your website or application. The developers at Google Chrome have a future vision of the web where third-party scripts provide value without disrupting the performance or user experience of websites. They share their information and insights from experiments with third-party scripts.

Why does React re-render? The real answer.

Have you ever wondered what triggers React to re-render? Even the most experienced developer might give you different answers if you ask. At OAK’S LAB, we are using “useCallback”, “useEffect”, and “useMemo” constantly in React, and it might cause some re-renders in different scenarios. To finally understand the behavior, Josh Comeau provides the explanation.

Inspiring Engineering Ladders for Engineer Managers

Engineering levels and ladders differ from company to company. At OAK’S LAB, we found inspiration by looking at this framework for engineering managers. It’s an excellent way to evaluate how we are doing and how we can improve the way our department works.

Output: First, Fourth, Third, Second.

It’s all connected to the JavaScript event loop at the end. JavaScript treats all events in a different order, and putting “0” in setTimeout does not make the timeout an immediate call.
