The Micro-Frontend Architecture Handbook

iframes: Secure and isolated, but clunky as dial-up. Best for legacy cleanup missions. Web Components: Native and framework-agnostic, perfect for reusable UI with Shadow DOM flair. single-spa: Juggles multiple SPAs with the finesse of a circus, though it gets chatty. Module Federation: Real-time module confab, shackled to Webpack, yet import maps are optional. Each has its quirks and perks for micro-frontends—choose your weapon wisely.
