• Or anywhere you prefer
• Gatsby's growth and development seems to be stagnating as Jamstack has fallen out of favor compared to Next.js.
• React's stubborn incompatibility with Web Components is frustrating but may be more of an indictment of Web Components' limitations.
• CSS-in-JS causes fragmentation across environments like client vs server rendering, so the React ecosystem is moving away from it. Differences in tradeoffs between browser and mobile environments make it a difficult problem.
• New devtools have been released for React Server Components and Remix that help inspect behavior on client and server. Good devtools are a huge force multiplier.
• Publishing libraries with proper ESModules support is still very challenging and undocumented. Deno may help smooth the process.
• React production builds now have sourcemaps thanks to impressive work by Mark Erikson! This will massively help debugging libraries like React in production.
• Official React + TypeScript documentation has finally landed. Orta did a great job with it.
• Try out new versions of Redux Toolkit and React-Redux in beta. Provide feedback!
• Expo had a big release week with improvements to builds, updates, SQLite, CLI plugins, and more as React Native marches forward.
