Bcrypt And PassportJs User Registration
There are multiple methods to hash a password using bcrypt.js. Like you can use Promise, async, sync. The one that you used is async that generates salt and hash on a separate function calls. One error in your code is it should be password:req.body.password you need to use dot(.) after body instead of colon(:).
Besides your code one of the methods to hash a password is
router.post('/kayıt', async (req, res) => { //hashed password const salt = await bcrypt.genSalt(10); const hashedPassword = await bcrypt.hash(req.body.password, salt); const user = new User({ isim: req.body.isim, email: req.body.email, password: hashedPassword }); user.save(function(err) { if (err) { console.log(err); } else { res.redirect('/'); } }); });You can have a look here.
