express get slash value

Code Example:

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

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

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

1. Require the Express module:

2. Import the Express module using the require function and assign it to the variable express.

3. Create an Express application instance:

4. Create a new instance of the Express application and assign it to the variable app by calling the express function.

5. Handle the GET request for the root path ('/'):

6. Use the app.get method to define a handler for GET requests to the root path ('/') of the server.
7. The handler function takes two parameters: req (the request object) and res (the response object).

8. In this example, the handler sends the response 'Hello World!' back to the client using the res.send method.

9. Start the server:

10. Call the app.listen method to start the server and make it listen for incoming connections on port 3000.
11. The second parameter is a callback function that logs a message to the console once the server is running.

This code sets up an Express server that listens for GET requests to the root path ('/') and responds with 'Hello World!'.
