code to follow along my write up of a bcrypt expressJS example

index.js

// index.js
const express = require('express');
// import bcrypt and set the salt rounds
// read about salt in the readme
const bcrypt = require('bcrypt');
const bcryptSALTrounds = 10;

const app = express();
const PORT = 3000;

// REQUIREMENT FUNCTION #1
// http://localhost:3000/hash/dasdas
app.get('/hash/:stuff', async (req, res, next) => {
  // want to inspect params? uncomment :
  // console.log(req.params);

  const { stuff } = req.params;
  const hash = await bcrypt.hash(`${stuff}`, bcryptSALTrounds);

  res.send({ message: `${hash}` });
});

// REQUIREMENT FUNCTION #2
// http://localhost:3000/compare/$2b$10$DB0melt1B.3Fn7MfXwC17OIevWVhtSgXMrINkg9M4SEHdFgM6Myqm/dasdas
app.get('/compare/:hash/:stuff', async (req, res, next) => {
  // want to inspect params? uncomment :
  // console.log(req.params);

  const { hash, stuff } = req.params;

  const match = await bcrypt.compare(stuff, hash);
  if (match) {
    res.send({ message: 'match' });
  } else {
    res.send({ message: `not match` });
  }
});

app.listen(PORT, () => {
  console.log(`listening on port : ${PORT}`);
});

module.exports = app;
