This Week In React #278 : React Email, TSRX, ESLint plugin, Rspack RSC, TanStack | Vision Camera, Expo, Nano Icons, ExecuTorch | TypeScript Go

#reactnative #react

Hi everyone, Krzysztof and Filip from Software Mansion here 👋!

Big releases anchor the week. React Email 6.0 consolidates a fragmented ecosystem into one package, unlocking an embeddable editor and more reliable HTML rendering across mailboxes.

On mobile, Marc Rousavy shipped VisionCamera v5 with a full Nitro Modules rewrite, Worklets integration, pro controls, and a modular plugin architecture.

Heads up on the Vercel April 2026 incident: rotate your integration tokens if you use third-party integrations.

Also inside: Expo’s Series B, Seth Webster joining Expo, the Doctolib WebView-to-Native migration, and fresh releases from TanStack, React Hook Form, ExecuTorch, TS Go beta, Rspack RSC, and more.

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)

React Email 6.0

React email matures with a major release that cleans up a fragmented ecosystem. It makes version management much easier and stops the CLI and components from getting out of sync.

Key technical shifts:

Embeddable Editor: You can use the preview tool as a React component to show users how their emails will look directly in your own app.
Reliable HTML: The engine that turns React into email HTML handles more different mailboxes quirks.
Faster HMR: Faster switching between templates and preview, even with complex layouts

Moving away from modularization into one big package is a big step toward making the library stable and more capable. While it might slightly increase bundle size, it enables complex features blocked before, like the embeddable preview and advanced layout transformations.
