LZW Async

LZW Async is a JavaScript library developed for compressing text using the LZW algorithm.

This algorithm was created for compressing large text-based data and uses a simple dictionary for reusing the previously compressed data when possible.

Just like the original algorithm it does not need special dictionary files/arrays to decode the compressed data, but it can work with one if needed, also coming packed with a binary search tree for speeding it up.

LZW Async works with client-side (browsers) and server-side (Node.js) environments.

A working demo is included with the download package.

Requirements:

• JavaScript enabled on client side

Limitations:

• Only works with ASCII (up to 256) characters.
• The compression and decompression routines currently use separate dictionary implementations.
