Compression and decompression of data using zlib in Nodejs

Question

Can someone please explain to me how the zlib library works in Nodejs?

I\'m fairly new to Nodejs, and I\'m not yet sure how to use buffers and streams.

For anybody stumbling on this in 2016 (and also wondering how to serialize compressed data to a string rather than a file or a buffer) - it looks like zlib (since node 0.11) now provides synchronous versions of its functions that do not require callbacks:

var zlib = require('zlib');
var input = "Hellow world";

var deflated = zlib.deflateSync(input).toString('base64');
var inflated = zlib.inflateSync(new Buffer(deflated, 'base64')).toString();

console.log(inflated);
