Building Enterprise JavaScript Applications

Using the bcryptjs library

First, let's install it as a development dependency:

$ yarn add bcryptjs --dev

Then, import the genSaltSync and hashSync methods from the bcryptjs module and use them to generate a salt and digest. We will also store the salt and digest in the context to help us make assertions in subsequent steps:

import { genSaltSync, hashSync } from 'bcryptjs';...async function createUser() {  ...  user.password = crypto.randomBytes(32).toString('hex');  user.salt = genSaltSync(10);  user.digest = hashSync(user.password, user.salt);  const result = await client.index({ index, type, refresh,     body: {      email: user.email,      digest: user.digest,    },  });  ...}

Normally, we would use the asynchronous version of the hash method. However, since ...
