Jack Harrington sits down with Tanner Linsley to talk about the evolution of TanStack and where it’s headed next. They explore how early projects like React Query and React Table influenced the headless philosophy behind TanStack Router, why virtualized lists matter at scale, and what makes forms in React so challenging. Tanner breaks down TanStack Start and its client-first approach to SSR, routing, and data loading, and shares his perspective on React Server Components, modern authentication tradeoffs, and composable tooling. The episode wraps with a look at TanStack’s roadmap and what it takes to sustainably maintain open source at scale. We want to hear from you! How did you find us? Did you see us on Twitter?

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.

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.

Dominic Gannaway joins us to talk about Ripple.js, a new TypeScript-first UI framework built with its own templating language and a focus on clarity and reactivity. We explore how Ripple.js handles fine-grained updates through its track and block system, why it avoids global state, and how context plays a key role. Dominic also walks us through the developer experience, from the language server and VS Code integration to syntax highlighting and the Prettier plugin, plus how the framework handles error boundaries, server-side rendering, future plans, and more.

Ever wondered how source maps actually work? In this episode, Nicolo Ribaudo, Babel maintainer and TC39 delegate, breaks down how source maps connect your JavaScript, TypeScript, and CSS back to the original code — making debugging, stack traces, and observability smoother in Chrome dev tools. We dive into how source maps help in both development and production with minified code, explore tools like Webpack, Rollup, Next.js, and Svelte, and share when you should turn off source maps to avoid confusion.

Andreas Rossberg unpacks WASM 3.0, covering new capabilities like garbage collection, exception handling, tail calls, and support for 64-bit addressing with multiple memories. The discussion explores deterministic profiles following relaxed sim, WebAssembly’s capability-based security model, and advances in sandboxing and module design. Andreas connects these features to practical use cases in JavaScript engines and applications like Google Sheets, then looks ahead to experimental work on threading, stack switching, and async programming models shaping the next phase of the WebAssembly ecosystem.

Jono Alderson joins the podcast to discuss why semantic HTML still matters today. He shares how thoughtful markup can improve accessibility and performance, from using the picture tag and responsive images to optimizing with content-visibility CSS. The conversation dives into common pitfalls like div soup, the shift toward more template-centric design, and techniques for improving the critical rendering path. Jono also discusses preloading, HTTP early hints, and the evolving role of structured data, LLMs, and Google’s trust signals in shaping a more meaningful and efficient web.

In this episode of PodRocket, Adam Argyle and Kevin Powell discuss the results of the latest State of CSS survey and share how new capabilities like functions, mixins, nesting, and container queries are changing the way developers approach styling. We dive into the ongoing conversation around Tailwind and pre-processors, and look at the practical impact of features such as scroll driven animations, view transitions, and cascade layers. Adam and Kevin also explain how advances like relative color syntax and app property are making CSS variables more dynamic and reliable. Along the way, we touch on browser interoperability and imagine what’s ahead for CSS, from motion blur to fit text and beyond.

Is the web breaking under the weight of AI crawlers, platform consolidation, and nonstop security breaches? We dive into the state of browsers, developer burnout, and whether tech regulation can actually keep up. In this panel discussion: We debate if robots.txt and AI licensing standards like RSL can realistically control how AI scrapes the web. The fallout from DIA’s acquisition by Atlassian and what it means for indie browser innovation (like the Helium browser, Zen) in a Chromium-dominated world. Why Google’s antitrust victory might embolden other tech giants, and what that means for competition. How supply chain attacks like the NPM malware and Shai Hulud worm are exploiting GitHub workflows and package vulnerabilities. The pushback against AI mandates at work, including Coinbase’s controversial policy requiring developers to use Copilot.

Feross Aboukhadijeh, founder of Socket, joins us to break down the recent wave of NPM supply chain attacks hitting the JavaScript ecosystem, including how attackers used phishing to target developers, snuck malware into popular packages like Prettier and "is", and even abused tools like Claude, Gemini, and TruffleHog. We dig into how GitHub Actions vulnerabilities were exploited, what makes postinstall scripts risky, and and what you can do to protect yourself from future attacks.

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.

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.
