In this article, we would like to show you how to make AJAX DELETE requests in Express.js. 

1. Express.js DELETE method example

In this section, we use Express.js to handle DELETE requests.

Note: it is required to add external library to run below example, so use:

npm install express

index.js

const express = require('express');

const port = 3000;
const app = express();

app.delete('/examples/:id', (request, response) => {  
  const idToDelete = request.params.id; 
  // delete resource with ID: idToDelete

  response.send('Example removed');
});

app.listen(port, () => {
    console.log(`server is listening at http://localhost:${port}`);
});

To run the server use: 

node index.js

Output:

server is listening at http://localhost:3000

2. Pure JavaScript (Vanilla JS) AJAX DELETE request

The following is an example execution of a fetch method that sends DELETE requests.

<!DOCTYPE html>
<html>
  <body>
    <script>

      fetch('/examples/5', {
        method: 'DELETE'
      })
        })
        .then(res => response.text())
        .then(res => console.log(res))
        .catch(error => {
          console.error('Error:', error);
        });

    </script>
  </body>
</html>
