sha256-es

Cryptographic hash library producing a 256-bit (32-byte) hash value

node

Import SHA256 and call .hash() with a string (you might need to transpile the codebase from ES6 due to lack of support for modules and other features):

import SHA256 from 'sha256-es';
const hash = SHA256.hash('abc');
console.log(hash);

Example output:
