how to redirect route in express code example

Example 1: javascript redirect

res.redirect('http://example.com')
res.redirect(301, 'http://example.com')

Example 3: express url redirect

const app = require('express')();

// The `res.redirect()` function sends back an HTTP 302 by default.
// When an HTTP client receives a response with status 302, it will send
// an HTTP request to the URL in the response, in this case `/to`
app.get('/from', (req, res) => {
  res.redirect('/to');
});
app.get('/to', (req, res) => res.send('Hello, World!'));
