Fixing a NodeJS Digital Envelope Routines Error

2022-11-08 2 min read Tips and tricks

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

> create-wasm-app@0.1.0 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 should all compile.

$ npm run build

> create-wasm-app@0.1.0 build
> webpack --config webpack.config.js

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

Cheers!
