| 6/18/26 | ![]() App Store Connect CLI With Rudrank Riyam | React Universe On Air | Rudrank Riyam joins React Universe On Air to talk about App Store Connect CLI, an open-source tool for automating App Store Connect workflows without living in the dashboard. What started as a way to pull TestFlight feedback turned into a broader interface for metadata, submissions, localization, analytics, reviews, and release operations. Mike Grabowski and Rudrank discuss why these workflows are a strong fit for CLI automation, why Go became the right language for an agent-built tool, how teams are using it in CI/CD and agent workflows, and what changes when multiple coding agents build against the same codebase. They also get into code structure, command design, agents.md, public vs. private App Store Connect endpoints, and what changed after Rork acquired the project while keeping it open source. What we cover: - Why App Store Connect workflows are a good fit for CLI automation - How the tool handles TestFlight feedback, metadata, localization, analytics, reviews, and submissions - Why Rudrank chose Go over Swift for an agent-built CLI - What he learned from running multiple agents against one open-source project - How clear structure and command naming make a codebase easier for both humans and agents - What Rork’s acquisition means for the project going forward Guest: Rudrank Riyam is a software engineer at Rork and the creator of App Store Connect CLI. He works at the intersection of Apple development, release tooling, and agentic workflows. | — | ||||||

| 4/9/25 | ![]() TanStack Ecosystem with Tanner Linsley: React Query to TanStack Start | React Universe On Air #50 | Tanner Linsley joins React Universe On Air to unpack the evolution of the TanStack ecosystem—from React Table and React Query to TanStack Router and the newest addition to the family, TanStack Start ✨ What started as internal tooling for Nozzle became a suite of libraries that shaped how developers think about server state, routing, and full-stack React apps. In this episode, Tanner shares the technical decisions behind building framework-agnostic, headless tools—and explains why client-side architecture still matters in a server-first world. You’ll also hear why TanStack Start isn’t just another full-stack framework, how React Server Components could be treated like server state, and what’s coming next for TanStack Router. If you're building React apps at scale or deciding how to modernize your frontend stack, don’t skip this one!

| 3/5/25 | ![]() Multiple TV Platforms, One Codebase: React Native TV App Development | React Universe On Air #49 | Eighteen TV platforms, one codebase—what could possibly go wrong? Tune in to find out how to tackle the technical and UX challenges of building for Android TV, Apple TV, Fire TV, Tizen, and more—all with React Native! In the 49th episode of React Universe On Air, Łukasz Chludziński (https://x.com/lukasz_app) teams up with Michael Khirallah (https://x.com/mkralla11), Senior Director of Engineering at DIRECTV, and Chris Trag (https://x.com/chris_trag), Developer Evangelist at Amazon, to discuss why cross-platform development is not just a time-saver but also a way to deliver a consistent user experience. You know that at Callstack, we’re all about performance—and with devices like Samsung’s Tizen TVs released in 2017 (running Chromium 47!), performance is a serious concern. That’s why we asked our guests to share real-world techniques for optimizing TV apps, from architectural choices to strategies that avoid unnecessary performance hits on newer devices. The complexity of TV app development doesn’t stop at coding, though. Our host and guests know it all to well, so they couldn’t help but discuss how they balance unit, integration, automation, and manual testing, leveraging tools like AWS Device Farm and custom-built frameworks to ensure stability across all supported platforms. What’s in it for you? Tips on automating QA without compromising thoroughness and why manual testing remains crucial for end-user experience. Want to get started with React Native TV app development?
