You don't need to install external packages to hash a string using the SHA-1 hashing method.
Node.js comes with a built-in package called
crypto that you can use. Here's a simple way:
const crypto = require('crypto') const str = 'This is the string I want to hash.' const hash = crypto.createHash('sha1').update(str).digest('hex')
str, hashed using SHA-1 to create a shorter string that is fairly unique to the original string.
