This is a simple node function that generates a hash from a plaintext value using the Bcrypt library.

bcrypt-hash-generator.js

const bcrypt = require('bcrypt');
/**
 * @description Generate bcrypt hash from plaintext value

 */
const plainTextPassword = 'changeMe';
const saltRounds = 10;
bcrypt.genSalt(saltRounds, (saltErr, salt) => {
  if (saltErr) {
    return Error('Bcrypt generate salt failed: ' + saltErr);
  } else {
    bcrypt.hash(plainTextPassword, salt, (hashErr, hash) => {
      if (hashErr) {
        return Error('Bcrypt hash failed: ' + hashErr);
      } else {
        console.log(hash);
