New open-sourced lib by Meta for creating extensible text editors (with a system of plugins to support mentions, hashtags, collaborative editing...). It seems to be a modern, lightweight alternative to Draft.js (no need to use ImmutableJS this time 😏). Doesn't specifically depend on React, but provides an official binding. Can be used by other frameworks and could even target other plateforms (iOS support planned)
Mitosis is a tool that allows you to create a design system with a dialect close to React/JSX (inspired by Solid). Mitosis is able to compile these components to various frameworks (React, Angular, Svelte, React-Native...). This can be handy for large companies that use multiple frameworks over time. This official article is a good introduction.
Explains how to manage 2 forms associated with the same Remix route. It's only possible to have one
ActionFunction per route, so the best solution seems to be to use the
action attribute on the submit button.

The upcoming Storybook 6.5 will include performance improvements to improve the local DX through lazy compiling stories: 3x faster startup, 2x faster rebuild. The impact seems significant for larger Storybooks. Compare with Ladle, an alternative to Storybook released recently that also tries to improve performances.

CSS has a new
:has() selector, often referred to as a "parent selector", which allows CSS rules to be applied to a parent element based on children. For example, you can change the parent layout of a card, but only if it contains an image element: this avoids having to apply a variant class on the parent. This article illustrates this new feature with many use cases. I found interesting the possibility of applying CSS variables on html according to the value of a <select> (useful demo for theming or dark mode support). Currently only available in Safari and Chrome Canary, but support could improve fast.
Be careful not to abuse it: in a component model like React, it is better to limit yourself to targeting local classes to avoid breaking the encapsulation model of your component.
A new status code is officially added in the HTML spec. It allows sending "early hints" to the browser to prefetch/preload resources before receiving the 200 response from the server. It seems useful particularly for CDNs (read this Cloudflare article) which will be able to send cached early hints (or even predicted through machine-learning 🤯) while fetching fresh content from the origin server.
<dialog> added in Safari 15.4 and growing support, it's time to take a look at this new element.
