In my journey to learn Rust, I've decided to pick up this book called "Practical Rust Web Projects" by Shing Lyu.
In the last chapter, you walk through an example of packaging a WebAssembly module using wasm-pack and using the .wasm binary in a NodeJS application. On the step where I needed to compile the application, I ran into the following error:
$ npm run build
> [email protected] build
> webpack --config webpack.config.js
node:internal/crypto/hash:71
this[kHandle] = new _Hash(algorithm, xofLen);
^
Error: error:0308010C:digital envelope routines::unsupported

Node.js v18.7.0
After a bit of Googling, I ran across someone suggesting to run the following command:
$ export NODE_OPTIONS=--openssl-legacy-provider
Then run the build command again, and it compiled 🎉
$ npm run build

This is definitely not the proper fix in a production scenario, but good enough to get me through the example 😉
Cheers!
