In this episode, we're taking a deep dive into microfrontends, the architectural style that allows companies like Spotify and IKEA to build and scale massive web applications. We'll break down how this approach extends the philosophy of microservices to the user interface, enabling independent teams to develop, deploy, and manage their own features without getting in each other's way. We'll explore the core patterns for composing these independent frontends—from iFrames and Web Components to modern tools like Module Federation—and discuss the critical trade-offs in performance, complexity, and user experience. Finally, we'll look to the future, examining how emerging trends like edge computing and AI-assisted UI composition are set to revolutionize how we build the web.
