Nuxt 4.5 dropped with Vite 8 as default, Rspack rebuilt on Rsbuild 2, and experimental SSR streaming — plus a Nuxt 3 end-of-life date of July 31. Meta open-sourced Asterisk, an internal React component library battle-tested across 13,000 apps, built on StyleX with 150+ accessible components. Angular 22 quietly switched HttpClient from XHR to the Fetch API, which is mostly painless unless you track upload progress. ## Content **TLDR:** The biggest story today is Bun: Anthropic (which acquired Bun in December 2025) migrated 535,000 lines of Zig to Rust in 11 days using 64 parallel Claude Code agents at a reported $165,000 in API costs. Nuxt 4.5 dropped with Vite 8 as default, Rspack rebuilt on Rsbuild 2, and experimental SSR streaming — plus a Nuxt 3 end-of-life date of July 31. Meta open-sourced Asterisk, an internal React component library battle-tested across 13,000 apps, built on StyleX with 150+ accessible components. Angular 22 quietly switched HttpClient from XHR to the Fetch API, which is mostly painless unless you track upload progress. --- ## Bun rewrites 535k lines of Zig to Rust in 11 days using 64 parallel Claude agents After Anthropic acquired Bun in December 2025, the team migrated the entire codebase from Zig to Rust in 11 days using 64 parallel Claude Code agents, at an estimated $165,000 in API costs. The rewrite passed 100% of Bun's TypeScript test suite. Motivations cited include memory safety issues in Zig and a larger Rust contributor ecosystem. Zig's creator pushed back, arguing the bugs came from rushed engineering rather than Zig itself — and there are real questions about shipping 535k lines of largely unreviewed AI-generated code in core infrastructure.

Experimental SSR streaming flushes the HTML shell immediately rather than waiting for full server render, cutting Time to First Byte on data-heavy pages. The release also adds stable error codes (format: NUXT_E1001), a useLayout composable, named views via filename convention, and an enabled option on useFetch and useAsyncData. Nuxt 3 reaches end-of-life on July 31, 2026.

It ships with 150+ accessible components and a theming system that generates design tokens from a handful of high-level inputs — brand color, typography scale, border radius, motion speed. Unlike shadcn/ui, components live in a central package so upstream fixes propagate automatically. There's a Tailwind bridge for mapping tokens to utility classes and a CLI built for loading component docs into AI agent context.

For most apps this is a zero-change upgrade with better SSR compatibility, native streaming, and improved service worker integration. The one real breaking change: FetchBackend does not fire UploadProgress events, so anything using reportProgress for file uploads needs to explicitly opt back into XHR with withXhr().
