I’ve been writing a bunch of jest tests recently for libraries that use the underlying
To use the
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
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;
