How does compression.default work?

compression.default is a function that creates middleware to compress HTTP responses using gzip, deflate or brotli compression methods in order to reduce the size of the response body sent to the client. When a client sends a request with an Accept-Encoding header containing any of these compression methods, the middleware will compress the response body using the method specified by the header and set the appropriate Content-Encoding header in the response to indicate to the client that the response is compressed.

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

const app = express();
app.use(compression());

// other middleware and routes

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

In this example, the compression() function is used as middleware for an Express.js server to compress responses before sending them to the client.
