Kent C. Dodds: If you’re experiencing React performance issues, try this: “Lift” the expensive component to a parent where it will be rendered less often.

Ship legacy JavaScript and CSS files in a Webpack Project with webpack-merge-and-include-globally
One of the projects that I’m working on is quite reliant on jQuery and Bootstrap. As we’re introducing new features (such as a few React-based components, and Stylus for CSS) in said project, we’ve also introduced Webpack into it. Now, we don’t want to run jQuery nor Bootstrap through Babel (using Webpack), but we want […]

An HTML attribute potentially worth $4.4M to Chipotle
Jason Grigsby: I recently found myself racing to fill out Chipotle’s online order form before my mother could find her credit card. In the process, I discovered a bug that could cost Chipotle $4.4 million annually. The form didn’t play nice with autocomplete and therefore would not get sent … The culprit? A JS library […]
An Introduction to Svelte
Developer Dave Ceddia, who had mainly been writing React before: A few months ago, Svelte 3 was released. I tried it out, ran through their tutorial, and built a few small things. And I can honestly say that I think writing Svelte feels even faster and easier than React. Svelte gave me the same spark, […]
