• The useless useCallback: React performance myths unpacked, with Dominik Dorfmeister (Repeat)

  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.

• First look at Prisma ORM v7 with Will Madden

  Jack Herrington talks with Will Madden about how Prisma ORM is evolving in v7, including the transition away from Rust toward TypeScript, less magic, and a new Prisma config file for more predictable good DX. They dig into Prisma Postgres, improvements to Prisma Studio, better support for serverless environments, and how JavaScript ORM tools like Prisma as an object relational mapper will fit into future agentic coding workflows powered by LLMs. Links LinkedIn: https://www.linkedin.com/in/willmadden Resources X thread with highlights: https://x.com/prisma/status/1991155390080598366 Blog post: https://www.prisma.io/blog/announcing-prisma-orm-7-0-0 YouTube video: https://www.youtube.com/watch?v=AmIXJHL-sBU Refreshed website homepage: https://www.prisma.io Docs with new getting started guide: https://www.prisma.io/docs ORM: https://www.prisma.io/blog/orm-6-12-0-esm-compatible-generator-in-preview-and-new-options-for-prisma-config https://www.prisma.io/blog/why-prisma-orm-generates-code-into-node-modules-and-why-it-ll-change https://www.prisma.io/blog/from-rust-to-typescript-a-new-chapter-for-prisma-orm https://www.prisma.io/blog/try-the-new-rust-free-version-of-prisma-orm-early-access https://www.prisma.io/blog/rust-free-prisma-orm-is-ready-for-production Prisma Postgres: prisma.io/postgres We want to hear from you!

• GitHub’s Octoverse: TypeScript, Copilot, and Open Source Struggles

  In this episode of PodRocket, Jack and Paige dive into the latest GitHub Octoverse report, covering trends like shipping faster with AI, the dominance of TypeScript as the top language, the rise of AI-generated pull requests, and the concerning drop in code review comments. They unpack the growing role of Copilot, the tension between OSS contributions and burnout, and the surge in AI infrastructure projects like Ollama. The discussion also touches on open source governance, the docs gap, prompt injection risks, and whether AI-powered browsers can succeed beyond the dev crowd.

• Speeding up the web with the speculation rules API | Barry Pollard

  Barry Pollard from the Chrome devrel team joins PodRocket to discuss the speculation rules API, a new browser feature designed to improve web performance through prefetch and pre-render techniques. Barry breaks down the history of speculative loading, contrasts SPA vs MPA behavior, and explains the nuances of hover prefetching, conservative prefetch, and the powerful new pre-render until script mode. Learn how Shopify and WordPress are adopting the API, what telemetry from Chrome Status reveals, and what developers need to know about potential pitfalls, caching behavior, and how the API is becoming a standard for static sites and e-commerce performance.
