How do username and password values ​​get into Password js?

Question

Node.js

I've lost count of how many times I cursed the day I switched from PHP to Node.js. The essence of the question is that I get email, password values ​​with Ajax.

app.post('/login', (req, res) => {
    var data = JSON.parse(req.body.remodal);
    console.log(data.email, data.password);	
  })
//passport.js
passport.use(new LocalStrategy(function(username, password, callback){
//Как передаются username и password
}))

But I have no idea how to pass them to passport.js. Please answer the question in more detail. Thanks in advance.

By default, LocalStrategy looks for the username and password fields in `req.body`. But since your data comes in a different format, you either need to manually report the necessary data to req.body, or connect the body-parser so that it decodes the incoming json, + you need to tell LocalStrategy where to get the data from. It's done like this:

const bodyParser = require('body-parser');

app.use(bodyParser.urlencoded({ extended: false }));
app.use(bodyParser.json());

passport.use(new LocalStrategy({
  usernameField: 'remodal[email]',
  passwordField: 'remodal[password]'
}, function(username, password, callback) {
  console.log(username, password);
}));

app.post('/login', passport.authenticate('local', {
  successRedirect: '/',
  failureRedirect: '/login'
}));

I have not tested the code, but I hope the idea is clear.
