nodejsZlib usage example

const zlib = require('zlib');
const fs = require('fs');
const gzip = zlib.createGzip();
const inp = fs.createReadStream('/var/www/examples/test.txt');
const out = fs.createWriteStream('/tmp/test.gz');  
inp.pipe(gzip).pipe(out);ctrl + cgithub

`require('zlib')` includes lib to work with compression	`zlib.createGzip()` creates new Gzip compression object
`require('fs')` library to work with file system	`fs.createReadStream(` create stream to read data from (file in our case)
`fs.createWriteStream(` create stream to write resulting (compressed) data to (file in our case)	`.pipe(` pipe object to the given stream
`inp.pipe(gzip)` pipes reading stream to gzip object (compress)	`.pipe(out)` then pipes compressed data to output stream (resulting `/tmp/test.gz` file)

Usage example

const zlib = require('zlib');  
const gzip = zlib.createGzip();  
const fs = require('fs');  
const inp = fs.createReadStream('/var/www/examples/test.txt');  
const out = fs.createWriteStream('/tmp/test.gz');  
inp.pipe(gzip).pipe(out);
