JSJ 397: Design Systems with Kaelig Deloumeau-Prigent

Hey everyone—it’s Steve Edwards here, and in this episode of JavaScript Jabber, I’m joined by returning guest Feross Aboukhadijeh, founder of Socket.dev, for a deep dive into the dark and fascinating world of open source supply chain security. From phishing campaigns targeting top NPM maintainers to the now-infamous Chalk library compromise, we unpack the latest wave of JavaScript package attacks and what developers can learn from them.Feross explains how some hackers are even using AI tools like Claude and Gemini as part of their payloads—and how defenders like Socket are fighting back with AI-powered analysis of their own. We also dive into GitHub Actions vulnerabilities, the role of two-factor authentication, and the growing need for “phishing-resistant 2FA.” Whether you’re an open source maintainer or just someone who runs npm install a little too often, this episode will open your eyes to how much happens behind the scenes to keep your code safe.🔗 Links & ResourcesSocket.dev – Protect your open source dependenciesFeross Aboukhadijeh on X (Twitter)GitHub Actions Security Best PracticesTruffleHog Blog – On secrets exposure in Git reposBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.

In this solo-hosted episode, I (Steve Edwards) dive deep into the world of modern monorepos with special guest Anton Stoychev from Yotpo. Anton shares his journey from the early days of PHP and IE6 nightmares to his current work in front-end infrastructure, performance optimization, and developer tooling.We talk about the challenges of managing dependencies, upgrading tools without breaking your codebase, and the evolution of developer experience across teams and companies. Anton also introduces Breakproof, Yotpo’s open-source monorepo template designed to make dependency management and tool upgrades painless—even when working with multiple Node.js versions, runtimes like Bun and Deno, and complex CI environments.If you’ve ever struggled with upgrading Jest, ESLint, or TypeScript in a large monorepo, or you’re curious how to isolate dependencies to keep your codebase maintainable over time, this episode is a must-listen.🔗 Links & Resources🔧 Breakproof on GitHub: breakproof.dev🧠 Yotpo LTD on GitHub: Yotpo Breakproof Base Monorepo💬 Follow Anton Stoychev: stoychev.dev on BlueSkyBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.

In this episode of JavaScript Jabber, I sit down with AWS’s Clare Liguori and Erik Hanchett to talk about Kiro, a brand-new AI-powered IDE that’s reimagining the way developers build software. We dive into how Kiro takes “AI-assisted coding” to a new level through spec-driven development — a process that focuses on defining requirements and collaborating with AI to break projects into clear, manageable tasks.We unpack what sets Kiro apart from tools like Cursor and Copilot, explore its supervised vs. autopilot coding modes, and even talk about how it handles UI design, planning, and complex legacy codebases. Clare and Erik share behind-the-scenes insights on how Kiro was built using Kiro itself, what’s coming next for the platform, and how developers can join the early-access community to help shape its future.🔗 Links & Resources:🌐 Kiro Official Site🧠 AWS Developer Advocate TeamBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.

This week on JavaScript Jabber, we dive deep into the challenges and opportunities of mixing and matching frontend frameworks in modern applications. I’m joined by Dan Shapir, Steve Edwards, and our special guest Hadar Geva, CTO and co-founder of Myop.dev. Together, we explore how companies are tackling multi-framework environments, the role of web components and iframes, and why module federation isn’t always as simple as it sounds.We also take a closer look at how AI is changing the way developers and even non-developers generate code, the risks of integrating AI-written components, and strategies for safely managing that code in production. If you’ve ever struggled with legacy frameworks, integrating AI-generated components, or wondered whether web components or local iframes are the better fit—this episode is packed with insights you won’t want to miss.Links & ResourcesMyop.dev – Hadar’s company, building solutions for mixing and managing micro-frontends.Web Awesome – Web components library mentioned during picks.AG Grid – Heavy-duty data grid solution.TanStack Table – Lightweight table solution by Tanner Linsley.ShadCN UI – Component library for modern React apps.Become a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.

In this episode of JavaScript Jabber, I sit down with Delaney Gilliland to dive into why most of us are building the front end wrong—and what a faster, leaner, and simpler alternative could look like. We explore his background in game development and military applications, which gave him a unique perspective on web performance and real-time data challenges. That perspective ultimately led him to create Datastar, a new framework designed to rethink the way we approach front-end development.We talk about the limitations of SPAs, the promise (and pitfalls) of tools like HTMX and Turbo, and how Datastar builds on web standards to deliver speed, efficiency, and simplicity without the baggage of heavy state management. Whether you’re curious about server-sent events, morphing strategies, or just want to see how front-end development could be done differently, this conversation will get you thinking about the future of the web.Links & ResourcesDatastar official sitehttps://x.com/DelaneyGillilanhttps://github.com/delaneyjBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.
