expressjsHow can I send an empty body using Express.js?

To send an empty body using Express.js, you can use the send() method. This method allows you to send an empty body response to the client. Here is an example of how to use it:

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

app.get('/', (req, res) => {
  res.send();
});

app.listen(3000, () => {
  console.log('Server running on port 3000');
});

This will send an empty body response to the client.

The code above consists of the following parts:

1. const express = require('express'); - This line imports the Express.js module.
2. const app = express(); - This line creates an Express.js application.
3. app.get('/', (req, res) => { - This line creates a route handler for a GET request to the root path.
4. res.send(); - This line sends an empty body response to the client.
5. app.listen(3000, () => { - This line starts the server on port 3000.

For more information, refer to the Express.js Documentation.
