CSS Grid Areas
A fresh look at the CSS grid template areas and how to take advantage of its full potential today. Jul 20, 2024 CSS Grid support has been widely available since March 2017 in all major browsers. Yet, here we are in 2024, and I still see few people using the grid template areas feature. It’s no surprise that many avoid template areas as making sense of the grid is challenging enough.

Reading and writing Node.js streams
Working with large datasets in Node.js applications can be a double-edged sword. The ability to handle massive amounts of data is extremely handy, but can also lead to performance bottlenecks and memory exhaustion. Traditionally, developers tackled this challenge by reading the entire dataset into memory at once. This approach, while intuitive for smaller datasets, becomes inefficient and resource
Private Browsing 2.0
When we invented Private Browsing back in 2005, our aim was to provide users with an easy way to keep their browsing private from anyone who shared the same device. We created a mode where users do not leave any local, persistent traces of their browsing. Eventually all other browsers shipped the same feature. At times, this is called “ephemeral browsing.” We baked in cross-site tracking preventio

Moving from express to fastify, pt 1
Express became the default for new JavaScript projects and has stayed there. In a typical week, express is downloaded from NPM 30 million times. It’s a roaring success in every way. A need for types Express is an expressive framework: like a classic Ruby or JavaScript framework, it lets you color outside the lines using loosely defined objects and types. Query string parameters in express become f

Understanding React Compiler | Tony Alicea
React's core architecture calls the functions you give it (i.e. your components) over and over. This fact both contributed to its popularity by simplifying its mental model, and created a point of possible performance issues. In general, if your functions do expensive things, then your app will be slow. Performance tuning, therefore, became a pain point for devs, as they had to manually tell React

What's coming next for ESLint - ESLint - Pluggable JavaScript Linter
When we released ESLint v9.0.0 in April, it was the first major release in 30 months and formally introduced the new configuration system. ESLint v9.0.0 also made some rule API changes to prepare the core for what’s coming next. After the release, we spent a lot of time creating compatibility utilities, a configuration migration tool, and a rule API transform utility to help the ecosystem move to

Layered Toggles: Optional CSS MixinsIn this article, I am sharing the next evolution of space & cyclic toggles, which allows us to create and apply optional mixins in CSS with the help of custom cascade layers, available today in every browser that supports them. I am no stranger to looking for various ways to apply some CSS conditionally, and through the years, went from using math as a way to ac
Inline conditionals in CSS, now? • Lea Verou
The CSS WG resolved to add if() to CSS, but that won’t be in browsers for a while. What are our options in the meantime? A couple days ago, I posted about the recent CSS WG resolution to add an if() function to CSS. Great as it may be, this is still a long way off, two years if everything goes super smoothly, more if not. So what can you do when you need conditionals right now? You may be pleased

Migrating to Next.js App Router with zero downtime — WorkOS
Can you really adopt Next.js App Router incrementally? At WorkOS, we learned that you can’t really migrate a complex app page by page without a hit to the UX. Instead, we worked out a migration guide that allowed us to test our entire app with App Router while still serving the Pages Router to users—before making the final switch. We use Next.js for all of our frontend apps at WorkOS. Recently, th
