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.

What if I told you someone managed to run Doom inside TypeScript’s type system? Sounds insane, right? That’s exactly what our guest Dimitri Mitropoulos did—and in this episode, we dive deep into the how, the why, and the mind-bending implications of this ambitious project. From type-level programming to the philosophical limits of Turing completeness, this is an episode that pushes the boundaries of what you thought was possible in JavaScript.We talk about how the TypeScript type system evolved to become Turing-complete, how Dimitri pulled off this seemingly impossible feat, and why “Doom-complete” might just be the new gold standard for computational capability. Along the way, we touch on functional programming, generics, recursion, and even some Lambda Calculus. It’s part computer science theory, part coding madness, and 100% geeky goodness.Episode Highlights[3:05] – Dimitri explains how a simple thought experiment turned into a year-and-a-half-long obsession[8:40] – The origins and significance of Turing completeness in type systems[14:15] – Why running Doom in TypeScript is more about proving limits than just showing off[19:55] – What it means to run programs inside the type system vs. TypeScript code itself[27:10] – ASCII art as output, functional recursion for game state, and hover-over frames in your editor[35:30] – How ignorance, determination, and obsession fueled the completion of the project[45:20] – Personal insights: balancing family, burnout, and passion while chasing an impossible dreamLinks & ResourcesDimitri MitropoulosMichigan TypeScript YouTube Channel – Dimitri's channel featuring the projectType Challenges by Anthony Fu – Advanced TypeScript exercisesSquiggleConf – The TypeScript-focused conference Dimitri co-foundedJosh Goldberg – TypeScript expert and co-organizer of SquiggleConfBecome a supporter of this podcast: https://www.spreaker.com/podcast/javascript-jabber--6102064/support.
