Hi everyone!
This week we celebrate the official death of IE11! 😄
I just came back from the App.js conf in Krakow: a very nice experience that I recommend to any React-Native dev 👌. Check my summary on Twitter!
Lots of interesting releases this week. And with React Summit coming up, it should continue 🤯
🙏 Support the newsletter:

Luca Casonato (Deno core team) unveils a new meta-framework for Deno based on Preact. Shares some common points with Next.js and Remix (FS routing, progressive enhancement). Islands architecture for hydration. No build step: compile on the fly. To be tested!
A new performance testing tool for React should be open-sourced next week. Measures and counts renders of a given scenario, snapshot them, and generates a report on changes (possible to publish in a PR). Announced at App.js, the tool only supports React-Native for now: web support will come later.
Million is a Virtual DOM solution supported by Vercel, which proposes to use a compiler to improve performance and reduce size (inspired by Svelte). The Million + React integration package has just been released. All this seems promising, but not yet ready for production.
A digest of the latest Gatsby news, with detailed blog posts on each topic. Some of those topics:
  • Script Component
  • GraphQL TypeGeneration
  • Image CDN GA
  • Incremental Deploys for All Builds
Interesting feedback on the usage of Vite in the Shopify Hydrogen meta-framework. There are advantages in terms of DX via the use of ES modules in dev, but also for the SSR and the integration of React Server Components thanks to its plugin system.
