remove .html from url express js

To remove the ".html" extension from a URL in Express.js, you can follow these steps:

1. Install the "path" module by running the command: npm install path

2. Import the "path" module into your Express.js file using the following code: javascript const path = require('path');

3. Create a route handler for the URL that you want to remove the ".html" extension from. For example: javascript app.get('/example', (req, res) => { // Your route logic here });

4. Within the route handler, use the path.parse() method to get the filename and extension from the URL. For example: javascript app.get('/example', (req, res) => { const { name, ext } = path.parse(req.url); // Your route logic here });

5. Check if the extension is ".html" using an if statement. If it is, remove the extension by concatenating the filename and a blank string. For example: ```javascript app.get('/example', (req, res) => { const { name, ext } = path.parse(req.url);

   if (ext === '.html') { const filenameWithoutExtension = name + ''; // Your route logic here } }); ```

6. Continue with your route logic using the filenameWithoutExtension variable. For example, you can render a template or send a response with the modified URL: ```javascript app.get('/example', (req, res) => { const { name, ext } = path.parse(req.url);

   if (ext === '.html') { const filenameWithoutExtension = name + ''; // Your route logic here res.render(filenameWithoutExtension); } }); ```

By following these steps, you should be able to remove the ".html" extension from a URL in Express.js.
