Welcome to the 157th issue of React Weekly — your weekly roundup of the most useful news, tools, tutorials, and discussions from the React ecosystem.
This week in React: This week highlights a mix of stability, performance, and ecosystem shifts. React shipped security patches across multiple versions, while React Native continues to improve its performance layer. At the same time, teams like GitHub and MDN are sharing deeper architectural lessons, from optimizing large-scale React rendering to moving beyond React entirely in some cases.
On the tooling side, there’s growing momentum around alternative frameworks and stacks, with migrations away from Next.js and increased interest in client-first and hybrid approaches. Meanwhile, the component ecosystem remains active, with steady updates across UI libraries, developer tools, and React Native capabilities.
