Hi everyone!

This week is relatively calm in terms of React news, but I’m saving an exciting React core update for next week, so don't miss my next email 👀!

On the React Native side, we have so many links that it’s a bit overwhelming 😆 And Expo SDK 54 is not even out yet!

Beware of the massive npm supply chain attack affecting very popular packages such as chalk and debug. To mitigate the impact of compromised dependencies, package managers such as pnpm and Yarn are considering an option to avoid installing freshly published packages. This could give enough time for security scanners to report vulnerabilities.

As always, thanks for supporting us on your favorite platform:

​Shadcn Admin Kit: Your Open-Source Shortcut​

Do you love how Shadcn/UI puts you back in the driver's seat with components you actually own? Shadcn Admin Kit builds on that same philosophy, but for application logic. 💡

Instead of starting from scratch on auth, data fetching, CRUD, data tables, forms & validation, and error management, Shadcn Admin Kit provides a ready-to-use foundation that fits right into your project.

It's built on the stack you would choose: Tailwind CSS, Radix UI, Shadcn/UI, React Router, TanStack Query, and React Hook Form, all brought together by the same team that built React-Admin.

Whether you're a startup founder or a lead dev, Shadcn Admin Kit helps you ship fast without sacrificing code quality. No black box or lock-in. Just open-source magic. ✨ Try it out now!

​An Interactive Guide to TanStack DB​

A greatly interactive article that shows how React Query can become verbose and complex, and how TanStack DB is designed to fill the gap with new primitives:

• Collections: load large amounts of typed, relational data on the client
• Live Queries: filter/process/join collections at incredible speed, with fewer React re-renders
• Transactional Mutation: perform optimistic updates with less boilerplate and automatic rollbacks

All this without changing your backend endpoints. And you can go even further and adopt a sync engine like ElectricSQL to benefit from real-time synchronization and handle larger datasets.
