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.

In this episode of JavaScript Jabber, we dive deep into the world of vibe coding—what it means, how it works in practice, and why it’s changing the way developers build software. I’m joined by Anthony Campolo, who shares his hands-on experience developing AutoShow, an app that automates podcast show notes, using AI-assisted workflows. We talk about how tools like Claude, ChatGPT, and Gemini accelerate development, the role of rule files, and the balance between automation and manual QA.Along the way, we explore the impact of LLMs on junior vs. senior developers, how companies are adapting AI-driven coding practices, and whether the future of software development still requires humans in the loop. This conversation blends real-world coding insights, practical tools, and some big-picture questions about where AI is taking the industry.Check out Anthony Campolo here.Become a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.

In this episode of JavaScript Jabber, we sit down with Vinicius Dallacqua, a seasoned software engineer with a passion for performance and developer tooling. Vinicius shares his journey from coding in central Brazil with limited connectivity to building cutting-edge tools like PerfLab and PerfAgent. We dive into the intersection of AI and DevTools, exploring how artificial intelligence is transforming performance debugging, web development workflows, and even the future of browsers.We also tackle the big questions: How do developers avoid bias when building in high-performance environments? What role will agentic browsers play in the evolution of the web? And how can AI-powered DevTools lower the barrier for developers intimidated by performance profiling? If you’re curious about the future of frontend performance, DevTools, and AI-driven development, this conversation is packed with insights.Links & ResourcesPerfLab – Performance tooling platformPerfAgent – AI-powered DevTools assistantVinicius Dallacqua on X (Twitter)Paul Kinlan’s AI Focus – Essays on AI and the webPerfNow Conference – Leading performance conference in AmsterdamBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.
