This project has been created when no compression library existed for Node.js. This isn't the case for years. This repository is mainly kept for backward compatibility with some of the very ancient software of mine.
Synchronous zlib Buffer compression library for Node.js.
compress = require('compress-buffer').compress;
uncompress = require('compress-buffer').uncompress;
var rawData = fs.readFileSync("/etc/passwd");
var compressed = compress(rawData);
var uncompressed = uncompress(compressed);
uncompressed == rawData // true!For the sake of the KISS principle. Most of the time you don't need a streaming compression, you need to compress an existing and already complete data.
compress() takes two arguments: the data (must be a Buffer()) and optional compression level which must be within 1..9. It returns compressed Buffer() or undefined on error.
uncompress() takes a single argument: the data (must be a Buffer()) and returns uncompressed Buffer() or undefined on error.
Both functions could throw exceptions in the following cases:
- zlib initialisation fails;
- first argument is not a
Bufferinstance.
npm install compress-buffer
or
npm install .

- A lot of thanks for important suggestions goes to Konstantin Käfer who implemented a nice similar module node-zlib (https://github.com/kkaefer/node-zlib) earlier than me;
