Design Patterns in Modern Web Development

Posted by JaneDoe • Sep 12, 2025 • 3:45 PM

Hey everyone! 👋

I've been revisiting classic software design patterns and wondering how they translate to today's front‑end frameworks like React, Vue, and Svelte. For instance, does the Observer pattern still have a place now that we have built‑in reactivity? What about Strategy for handling different UI behaviors?

I'd love to hear about real‑world examples or anti‑patterns you've encountered. Let’s discuss!

Great topic! I think the Observer pattern lives on in hooks like useEffect and the subscription model of RxJS. In Redux you also see it with selectors.

For Strategy, I often use a type prop to choose which component to render. With TypeScript this is type‑safe and very clean.

Be careful with the Singleton pattern in React – it can lead to hidden state that’s hard to test.

I once used the Factory pattern to create form components based on a JSON schema. It saved a lot of duplication.
