How to Use window.crypto in Node.js
I've been writing a bunch of jest tests recently for libraries that use the underlying window.crypto methods like getRandomValues() and window.crypto.subtle key management methods. One problem I run into is that the window.crypto object isn't available, so I need to shim it.
To use the window.crypto methods, you will need Node 15+. You can set the window.crypto by importing the crypto package and setting it on the global:
const crypto = require('crypto').webcrypto;
// Shims the crypto property onto global
global.crypto = crypto;
I really loathe creating mock functions for missing libraries in Node because they can lead to faulty positives on tests; I really appreciate webcrypto being available!
