Statements Vs. Expressions
How to build connected components in Storybook
An official Storybook article that explains well all you can do with decorators: add a layout, global providers, mock a Redux store or requests... It can help to add "connected" components to your Storybook that otherwise can't be rendered due to context dependencies.
How I Estimate NPM Package Market Share (and how Redux usage compares to other libraries)
Mark Erikson (Redux) explains how he analyzes npm package usage trends, based on various more or less reliable tools. Download stats are often related to CI builds. He uses React state managers as an example. He now estimates Redux / React usage at 33% (previously 45-50%)
Actionless and Stateless Reducers in React
useReducer() is not reserved for complex cases: it can also be used for very simple state machines, like changing a boolean from false to true.
📜 Next.js: open external links in a New Tab: it can be interesting to create your own Link abstraction on top of the underlying framework to add extra behavior
📜 The Unlocked Possibilities of the :has() Selector: CSS feature. Interesting comparison with React rendering at the end.
📜 Atomic Forms in React: presents a bit Jotai-Form and the difference with more traditional approaches like Formik.
📜 Create a simple cookie with Remix: shows that the use of cookie in Remix is relatively simple, and close to the HTTP protocol
🧑🎨 Remix + Bun demo
🧑🎨 React-on-the-edge: Vercel demo that shows how to use React SSR (without Next.js) with the Edge Runtime. With or without streaming.
🐦 Remix loader type inference: PR merged to facilitate typesafe usage of the useLoaderData() hook 👌
🐦 Bun + React SSR: significant performance gains
📦 RemixBlocks: I find the idea interesting: nested routes Remix are full-stack which makes them a good candidate for copy/paste, quite similar to Tailwind.
📦 react-obsidian: dependency injection for React

TechTree - Introducing This Week in React Bounty Board
TechTree is building the first social-economic platform for developers - a place to help you unlock the real value of your knowledge and network!
The first major feature on TechTree is Bounties, a tool to help you earn money by referring your friends to open roles at top VC backed tech startups or find a job that might be right for you!
