express case sensitive routing

Express Case-Sensitive Routing

To enable case-sensitive routing in Express, you can set the caseSensitive option to true when creating an instance of the Express application. This will make the routing paths case-sensitive, so that '/users' and '/USERS' will be considered as different routes.

1. Create an instance of the Express application

javascript const express = require('express'); const app = express({ caseSensitive: true });

In this step, we import the express module and create an instance of the Express application while setting the caseSensitive option to true.

1. Define the routes

```javascript app.get('/users', (req, res) => { res.send('This is the users route'); });

app.get('/USERS', (req, res) => { res.send('This is the USERS route'); }); ```

Here, we define two routes, '/users' and '/USERS', with different casing. With case-sensitive routing enabled, these paths will be treated as distinct routes.

1. Start the server

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

Finally, we start the server to listen for incoming requests.

By setting the caseSensitive option to true when creating the Express application, you can ensure that routing paths are treated as case-sensitive, providing more control over the behavior of your routes.
