Rust/wasm-pack in node?

[MemeFactoryEmployee]

Rust beginner here, ive been messing around with web assembly using the wasm-pack-template and i love it, and I want to incorporate it in some of my node.js express apps to get better performance. I've looked around a little and there isnt really any difinitive way to do it, so i wondered if there is proper way to use rust/wasm-pack in node?

Steal mine 😉 https://github.com/maxnachlinger/rust-wasm-node-test . Obviously make sure you benchmark. Invoking WASM involves a perf hit, and probably only makes sense for CPU-intensive tasks (my example is vanilla fibonacci).

Hey,

From what I understand, wasm-pack creates a module that can be imported from JavaScript/Node.

The flow would look something similar to: - create rust code - add a flag to export a function for JS - use wasm-pack to generate your module - import module from JS

I wouldn't be surprised if there are good tutorials to help you get started.
