Turbopack: A Rust-Powered 'Successor' to Webpack — With over 3 billion downloads, webpack is the current champion of the bundlers (though Vite has been rapidly advancing). Vercel found it too slow and has funded work on Turbopack. It's a project to keep an eye on and boasts huge performance boosts over webpack or even Vite, but there are some limitations to take into account:

• It's arguable if it's a "successor" to webpack, as Turbopack can't do much of what Webpack can yet, and while they share a creator, webpack is an active project with maintainers of its own.
• It's very connected to React and Next.js 13 (also released this week – more on that next) – Vue and Svelte support is to follow.
• The similarly Rust-powered SWC is used to transpile JS/TS.
• Vite's Evan You posted 🐦 a Twitter thread with his thoughts on Turbopack so far.
• TLDR: Unless you're big into Next.js, stick with your existing tools.

Next.js 13 Unveiled at Next.js Conf — Next.js Conf 22 took place earlier this week and as well as Turborepo (above), Vercel unveiled the latest version of the site framework that has become 'inextricably linked' to React. It gains:

• Support for an app/ directory to improve routing, layouts, and Server Components support – can coexist with existing approaches.
• A new image component with on-demand optimization and the ability to display images without layout shift.
• A brand new font system.
