expressjsHow can I use Express.js to compress my files?

Express.js is a web application framework for Node.js that can be used to compress files. To compress files, you can use the compression middleware. This middleware compresses incoming requests and responses, and can be used to reduce the size of static files.

To use the compression middleware, you need to install it first:

npm install compression

Then, you can use the compression middleware in your Express application:

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

const app = express();

// Use the `compression` middleware
app.use(compression());

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

app.listen(3000);

The code above will compress all incoming requests and responses.

Code explanation

1. npm install compression - installing the compression middleware
2. const compression = require('compression'); - requiring the compression middleware
3. app.use(compression()); - using the compression middleware
