Hi everyone, Seb and Jan here 👋!

This week, we have news about popular React meta-frameworks. Next.js Adapters API should help host it anywhere without compromise. TanStack Start unveils a preview of its React Server Components. The React Compiler port to Rust is being actively worked on.

No major announcement in the React Native world, but still many interesting releases. React Native v0.85 should be released next week.

Axios has been compromised in a major supply chain attack. Stay safe and make sure to adopt security best practices!

Let's dive in!

​Still writing tests manually?​

Notion, Dropbox and LaunchDarkly have found a new testing paradigm - and they can't imagine working without it. Built by ex-Palantir engineers, Meticulous autonomously creates a continuously evolving suite of E2E UI tests that delivers near-exhaustive coverage with zero developer effort - impossible to deliver by any other means.

It works like magic in the background:

• Near-exhaustive coverage on every test run
• No test creation
• No maintenance (seriously)
• Zero flakes (built on a deterministic browser)

​Next.js Across Platforms: Adapters, OpenNext, and Our Commitments​

Next.js 16.2 now ships with a stable, typed, versioned Adapter API. It was built in collaboration with many partners: OpenNext, Netlify, Cloudflare, AWS Amplify, and Google Cloud. This helps ensure Next.js works well on every platform across all its features. There’s now a public test suite to verify your adapter, and Vercel also relies on it.

The Next.js Ecosystem Working Group explains Vercel’s commitment. Partners will not participate in Next.js design decisions and roadmap, but can still impact it through feedback. They will be kept in the loop early, have time to adapt, and get direct support to fix adapter breakage.

🎥 TanStart Start RSC preview​

Tanner Linsley gave a talk at React Paris last week. The 2nd part unveils for the first time what React Server Components will look like in TanStack Start, to be released very soon.

My highlights:

• Primitives: You have full flexibility to decide how to compose these RSC APIs, and can adopt them incrementally. RSC flight payloads are just streams of text; you can sync/cache/persist/manipulate these on your own terms.
• Composite Components: You don’t need ’use client’ directives, although they are supported. This new concept creates an explicit boundary between the server and the client. I assume it should be possible to co-locate client/server components in the same file.
• No Server Actions: A design decision for security reasons, but you can use server functions with validation.

What strikes me is just how different this is from Next.js. It feels more like a library than a framework, and it seems more in sync with the philosophy that initially attracted me to React: you make your own decisions, even though sometimes more flexibility means more glue code and ways to shoot yourself in the foot. In any case, I agree with Tanner: we deserve another React meta-framework—one that’s less opinionated and innovates in a different direction.

​RN ExecuTorch 0.8​

Software Mansion just dropped the biggest release to date for React Native ExecuTorch. Version 0.8 expands the library's capabilities far beyond its initial scope, introducing official support for bare React Native applications (no longer strictly tied to Expo) and deep integration with Vision Camera.

Key callouts:

• Vision Camera Integration: You can now seamlessly run ExecuTorch models directly on camera frames in real-time.
• New Computer Vision Models: The release introduces powerful new CV hooks, such as useInstanceSegmentation and useSemanticSegmentation.
• Bare RN Support: You can now use ExecuTorch in bare React Native apps by utilizing the bare React Native resource fetcher instead of the Expo one.
• Expanded NLP: Continues to grow its Natural Language Processing suite with implementations for Speech-to-Text, Text-to-Speech, Text Embeddings, and more.
