State of Node.js Performance 2024
The year is 2024, and Node.js has reached version 23. With two semver-majors released per year, it might be difficult to keep track of all aspects of Node.js. This article revisits the State of Node.js performance, with a focus on comparing versions 20 through 22. The goal is to provide a detailed analysis of how the platform has evolved over the past year. This is a second version of "The State o
A leap in the evolution of Airtable’s codebase: Scaling TypeScript to thousands of projects
By: Michael Mitchell, Patrick Hayes We previously wrote about how Airtable migrated its codebase from Flow to TypeScript. A few years and several TypeScript versions later, TypeScript is still a critical tool for preventing bugs early on in the development cycle. Back when the previous article was written, we had just over 50 TypeScript projects — mostly mirroring the top-level directory structure
How To Improve INP: Yield Patterns
In the following, we’ll go over different patterns we can use to yield to the main thread to improve the Interaction-to-Next-Paint (INP). Knowing how to improve INP is more important than ever, as it’s a metric reflecting User Experience (UX) and has recently been added to the Core Web Vitals (CWVs) – which are used by Google’s search ranking. We’ll take a look at which part of INP we’re targettin
How To Optimize Performance In Vue Apps | DebugBear

The Two Lines of CSS That Tanked Performance (120fps to 40fps) First published: 22/08/2024 I recently released Learn WCs. If you’ve seen it, you’ve likely noticed the animation in the background, where the coloured circles move diagonally across the screen. It looks like this: It works nicely on Chrome and Safari, but I noticed a severe drop in performance on Firefox. You might not be able to see
Common misconceptions about how to optimize LCP  | Blog  | web.dev
For this post, we used data from page navigations with a subresource image LCP in Chrome to take a look at the LCP sub-parts. We've looked at this kind of data before, but never from field data to see where real users are spending their time while waiting for a page's LCP. Like with Core Web Vitals, we took the 75th percentile (p75) of each LCP sub-part for each origin in the CrUX dataset, resulti

Mastering Node.js Performance Hooks
Node.js includes a built-in module called performance hooks for precise performance measurement. But why use it when you can simply log timestamps and calculate the difference between two dates? At least because it is precise. The module uses a monotonic clock that allows you, as a user, to make performance measurements and be sure that they are not corrupted. At first, I struggled to understand h
