browserify-zlib

What is browserify-zlib?

The browserify-zlib npm package is a JavaScript implementation of zlib for the browser. It uses the pako library under the hood and is designed to be used with Browserify. It allows you to compress and decompress data using the zlib library in a way that is compatible with browser environments.

What are browserify-zlib's main functionalities?

Compression

This feature allows you to compress data using deflate compression. The code sample demonstrates how to compress a string and encode it in base64.

var zlib = require('browserify-zlib');
var input = 'Hello World';
var compressed = zlib.deflateSync(input).toString('base64');
console.log(compressed);

Decompression

This feature allows you to decompress data that was compressed using deflate compression. The code sample demonstrates how to decode a base64 string and decompress it.

var zlib = require('browserify-zlib');
var compressed = 'eJzT0yMAAGTvBe8=';
var decompressed = zlib.inflateSync(Buffer.from(compressed, 'base64'));
console.log(decompressed.toString());

Other packages similar to browserify-zlib

pako

Pako is a high-speed zlib port to pure javascript that works in the browser. It is the underlying library used by browserify-zlib. Pako is generally faster than browserify-zlib because it is a lower-level library and does not include the additional Browserify wrapper.

node-zlib-backport

This package is a backport of Node.js's zlib module for older versions of Node. It provides similar compression and decompression functionalities but is intended for server-side use in Node.js rather than in browsers.

fflate

Fflate is a high-performance, low-level compression library for JavaScript. It offers similar compression and decompression capabilities as browserify-zlib but focuses on speed and efficiency, often outperforming pako in benchmarks.

README

browserify-zlib

Emulates Node's zlib module for Browserify using pako. It uses the actual Node source code and passes the Node zlib tests by emulating the C++ binding that actually calls zlib.

Not implemented

The following options/methods are not supported because pako does not support them yet.

• The params method
• The dictionary option
