Compressing HTTP responses
compression is a middleware function that compresses the response body that will be send to the client. This module uses the zlib module https://nodejs.org/api/zlib.html that supports the following content-encoding mechanisms:
- gzip
- deflate
The Accept-Encoding HTTP header is used to determine which content-encoding mechanism is supported on the client-side (for example web browser) while the Content-Encoding HTTP header is used to tell the client which content encoding mechanism was applied to the response body.
compression is a configurable middleware function. It accepts an options object as the first argument to define a specific behavior for the middleware and also to pass zlib options as well.

In this recipe, we will see how to configure and use the compression NPM module to compress the request body sent to the client. Before you start, create a new package.json file with the following content:
{
"dependencies": {
"compression": "1.7.2...
