React got hacked with David Mytton

December 16th, 2025  |  37 mins 54 secs

react, security

In this episode, Noel sits down with David Mytton, founder and CEO of Arcjet, to unpack the React2Shell vulnerability and why it became such a serious remote code execution risk for apps using React server components and Next.js. They explain how server-side features introduced in React 19 changed the attack surface, why cloud providers leaned on WAF mitigation instead of instant patching, and what this incident reveals about modern JavaScript supply chain risk. The conversation also covers dependency sprawl, rushed patches, and why security as a feature needs to start long before production.

react, react hook, react usecallback

In this repeat episode, Dominik Dorfmeister unpacks the pitfalls of React’s useCallback and useMemo, revealing how these hooks often introduce more complexity than performance gains. He explores the promise of the React Compiler, the practical power of the “latest ref” pattern, and strategies to boost code readability and maintainability at scale.

Learn why overusing useEffect and manual memoization can do more harm than good, and how teams can level up their PR reviews and performance practices using tools like the ESLint React Compiler plugin.React useCallback, React useMemo, React memoization, React performance optimization, React compiler, React hooks best practices, React ref pattern, useEffect pitfalls, React readability, React ES Lint plugin, latest ref pattern React, React virtualized lists, React performance myths, useEffect overuse, React self review PRs, Dominik Dorfmeister React, Tans Stack Libraries

Mark Dalgeish on mastering RSCs with React Router

September 18th, 2025  |  Season 4  |  31 mins 36 secs

react

Mark Dalgleish joins us to talk about the latest in React Router, including its growing support for React Server Components (RSC). He breaks down what RSC data mode, framework mode, and declarative mode mean for developers, and how features like the middleware API and route module API are simplifying work across tools like Vite and Parcel.

We also dive into how React 19, static site generation with RSC, and smarter data batching are reshaping performance and the future of server-side rendering in React apps.
