sha1-es

Cryptographic hash library producing a 160-bit (20-byte) hash value

node

Import SHA1 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 SHA1 from 'sha1-es';
const hash = SHA1.hash('abc');
console.log(hash);

Example output:
