Breaking Up with SVG-in-JS in 2023
Very comprehensive article on the various ways of using SVGs in a React app, and their impact on performance. Advises against "SVG-in-JS": you should avoid rendering SVG markup via React components and having the SVG code be present in the JS bundle, including via solutions such as the SVGR loader. With a few exceptions, it's best to avoid inlining SVGs in HTML: React Server Components aren't necessarily an ideal solution either. SVG sprites are a good solution.
👀 React.dev PR - Adds a TypeScript overview page: a doc page is coming soon to document the use of React APIs with TypeScript.
📜 Form validation with Conform, Zod, and Remix: Conform is a library that validates FormData on the server, respects Remix's progressive enhancement and displays errors on the client. I think we should be able to use it with Next.js Server Actions later?
📜 Declaring JSX types in TypeScript 5.1: explains the recent improvements to JSX typing, particularly for React.
📜 React Hook for Avoiding Flash of Empty UI While Data Transitions
📜 Creating a seamless multi-language user interface in React
📦 Next.js 13.4.8 - 1.5x faster local server startup and 54% faster updates: as announced, Vercel is working on performance optimisations to improve the Next.js DX. See Tim Neutkens' comment for more details.
📦 Styled-Components v6: some breaking changes well documented in an upgrade guide..
📦 Astro Starlight: official Astro template for documentation, with a low carbon footprint and the option of using React and MDX.
📦 TinyBase v4.0 - Reactive data store for local‑first apps - SQLite and CRDT integrations

📱 React-Native
Expo SDK 49 beta is now available
The new 49 SDK has just been released, in beta for around a week. A release packed with lots of great improvements, it's difficult to list them all. Here are my highlights:
React-Native v0.72
Expo Router v2 RC
Reanimated v3

React devtools built-in
Environment variables
Local Expo Modules
Experimental support for Fabric in expo-dev-client
Reinventing Camera Processing - TensorFlow Lite GPU straight from JavaScript
Marc Rousavy explains how he is able to run TensorFlow models on React-Native Vision Camera v3 (demo). His plugin has just been open-sourced in VisionCamera v3 rc.3. The article is fairly technical, explaining how it works internally to run at 60+ FPS. TLDR: it's now very easy to integrate a TensorFlow model into Vision Camera, and draw some real-time feedback via React-Native-Skia. There's no need to write native code, and all this logic can even be deployed via Over-The-Air updates!
📦 App Icon Badge: a super handy Expo Config Plugin to generate a different icon depending on the environment: dev, staging...
