Astro Server-Side Rendering
Astro is a modern meta-framework capable of using any UI lib (including React). It now supports server-side rendering, available experimentally in v1.0 beta. Like Remix, the framework offers a layer of adapters for deployment to multiple targets.
React-admin V4: Build Your Own Framework
François takes as an example a simple admin interface in React, based on MUI and React-Hook-Form. The code is initially quite verbose, 90 lines. He gradually refactors this code by creating reusable abstractions, to end up with a declarative and expressive code of 20 lines.
He explains that these abstractions are actually the v4 of React-Admin (v4.0.0-RC.1 available). This new version is based on a more modern stack and is more modular: it exposes high-level components (based on MUI by default, can be swapped) but also low-level primitives to create your own framework. See also the full series of v4 articles.
An Overlooked Factor For Performance Optimization In React
Interesting reflection on the need (or not) to memoize the value of a React context according to the position of the provider in the tree. Personally, I still prefer to always memoize for safety, as you never know if the provider will not be moved somewhere else.
Writing Redux Reducers in Rust
Feedback on the integration of existing Rust business code into a React app through WebAssembly and the challenges encountered: non-ideal binding, serialization WASM bridge cost... They need to access the same state on both sides (Rust and TypeScript). Solution: create the reducers in Rust, and return a state diff to TypeScript.
How to Create and Export Web Components From a React Application
Shows how to use React to create a Web Component. It looks relatively simple, and can be useful in some specific contexts 🤔. Not to be confused with the use of Web Components from React (will be officially supported later).
React components composition: how to get it right
Gives some hints on when/how to split into smaller subcomponents. Also evokes an important Clean Code principle (without naming it): Single Level of Abstraction.

BeJSconf: JavaScript Conference In Brussels & Online
BeJSconf is happening in Belgium next May 13th, hosting members of TC39 and core team members of the trendiest JS libraries and frameworks, who’ve got you awesome talks and hands-on practices to let you get deep insights into the insides of JavaScript.
Talks on XState, Components or Multicore JS… are only a few! More importantly, non-tech topics such as leadership, DevRel, DX and such will be on the menu.
BeJSconf is also a way to celebrate and have fun; all with relishing some good Belgian fries and beer during the planned after-event party.

Showtime - Remote - Top 1% (based on location)
Showtime is a decentralized social network ✨ You can think of it as the "Instagram for NFTs" where you can discover and support your favorite artists, create and showcase your digital art collection and soon be rewarded for the value you create. They plan to help artists reward their fans by letting them earn NFTs (instead of having to buy them).
They are using Expo with Expo Application Services. They are iterating as fast as the web3 ecosystem is moving by using React Native and Next.js together thanks to React Native for Web. They built a high-quality universal design system that works on iOS, Android and Web: Universal UI. They are planning to open-source the frontend monorepo very soon.
They just launched the beta on iOS and Android. Send a message to Axel on Twitter or an email at axeldelafosse@gmail.com to learn more.
PS: I used to work with Henry, one of the engineers at Showtime!
