reproducible-deflate for node and iojs

Alternative to zlib.createDeflate with guaranteed reproducibility.

Sometimes (e.g. when performing automated regression tests) it is important that the same input will always be compressed to the same output. Since the zlib library of node.js ships with node.js, and might even depend on the operating system in addition to the node.js version number. that can make no such guarantees. Therefore, we use a fixed version of the JavaScript-only implementation pako to offer reproducible results.

Installation

npm install reproducible-deflate

Usage

// Load the library
var rd = require("reproducible-deflate");

// create a deflate stream
var deflate = rd.createDeflate(options);

// use the deflate stream
deflate.pipe(output);
deflate.data(input);
deflate.end();

Options

The options to createDeflate are passed on to pako.Deflate.
