Synchronous 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
Buffer
instance.
npm install compress-buffer
or
npm install .
See LICENSE file. Basically, it's a kind of "do-whatever-you-want-for-free" license.
