Http Response

The Http Response object is all about sending output to the browser.

Some of the methods it supports are:

• res.send
• res.redirect
• res.render

send

To send some data to the browser use res.send. It’s the simplest way to send data to the client.

render

app.post('/add_product', function(req, res){
 res.render('product', {product :  data});
});

In the example above the response object is used to render a template to the client.

redirect

To redirect to another route look at the example below:

// redirect to the login route
res.redirect("/login");
