Is it possible to handle both ajax form submissions and browser post submissions in express.js?

Question

Is it possible to handle both ajax form submissions and browser post submissions in express.js?

On my website, I have implemented a contact form using express.js (4.0). I am contemplating how to manage the scenario where a user disables JavaScript.

If the last part of my routing function looks like this:

res.render('contact.jade', {
  title: 'Thanks for reaching out!',
  errors: errors,
  now: new Date().getFullYear()
});

Will this effectively handle both AJAX and traditional form submissions? Is there a more efficient way to handle this situation? (Could this impact performance in any way?)

Answer №1

If you're working with express, you can utilize req.xhr to check if the request includes the X-Requested-With header set to XMLHttpRequest. This is commonly set to true by frameworks or can be manually configured.

For instance:

if (req.xhr) {
    res.json(errors);
} else {
    res.render('contact.jade', {
        title: 'Thank you for getting in touch!',
        errors: errors,
        now: new Date().getFullYear()
    });
}
