Not deprecated alternative to body-parser in Express.js

I am going through the book Web Development with Node and Express and I got confused.

I was prompted to put below in my application file, but it looks like it is body-parser

outdated and won't work. How can I achieve the same functionality?

This is my current code:

app.use(require('body-parser')());

app.get('/newsletter', function(req, res){

    // we will learn about CSRF later...for now, we just
    // provide a dummy value
    res.render('newsletter', { csrf: 'CSRF token goes here' });
});

app.post('/process', function(req, res){

    console.log('Form (from querystring): ' + req.query.form); 
    console.log('CSRF token (from hidden form field): ' + req.body._csrf); 
    console.log('Name (from visible form field): ' + req.body.name); 
    console.log('Email (from visible form field): ' + req.body.email); res.redirect(303, '/thank-you');
});
