hashing password

// import our wrapper auth.js

// I don't recommed inserting body-parser middleware to your 'app'. Specify it per route.

router.post("/register", upload.none(), asyncHandler(async (req, res, next) => {

  // 'password' is the plain-text password, so we gonna hash it
    const hashedPassword = await Auth.hashPassword(password);
  
  // We are using node-postgres here('pg'). Raw SQL command. $1, $2 etc. is how you pass the values to it
  const query = `INSERT INTO account(fullname, email, password) VALUES ($1, $2, $3) RETURNING user_id, fullname, email`;
  // notice here we're storing just the hashed password! Zero-knowledge of user's password!
  const values = [fullName, email, hashedPassword];
  
  // do the db thing
  const { rows } = await db.query(query, values);
  
  res.status(200).send(rows[0]);
