  1. Excellent piece! There’s a little typo, though; under Registering the user, in the second line, you’ve written app.py instead of app.js
    Otherwise the walk-through is excellent

  2. I clone the repository in my WAMP folder and run project by [npm run start] it works! but whenever I go for /register route fill up the form and submit, terminal stop with crash report

    1. Change this code var result = db.query(‘SELECT email FROM users WHERE email = ?’, [email], async (error, res) => {
      To
      var result = db.query(‘SELECT email FROM users WHERE email = ?’, [email], async (error, ress) => {

    1. in the sections such as:
      var result = db.query(‘SELECT email FROM users WHERE email = ?’, [email], async (error, res) => {

      You need to change error,res to error, ress

  3. hello sir, i think there is a mistake in your codes. It is the password!==confirm_password part. When we run this code, the else if part does not run. I didnt understand how can i fix it. Can you help me please

      1. Yes, he says nothing but presumably it’s up to us to add an app.post that compares the hashed password with the one in the db and either accept or reject the login. The problem remains to make the other pages on the site aware that the user is logged in, either by maintaining a session on the server or providing the user with a token. That’s a whole other subject I guess the author did not want to tackle.

  4. In register.hbs (1)do change this “password-confirm” to “password_confirm”,,,,,(2)do change in app.js code where db insert query is written there should be little bit change instead of this “res”..write “result”there (3)in .env folder change this “DATABASE_ROOT” to “DATABASE_USER” (4)remove following code from app.js ” const path = require(“path”)
    const publicDir = path.join(__dirname, ‘./public’)
    app.use(express.static(publicDir))”
