GZIP in pure JavaScript (works in the browser)

Package Exports

  • gzip-js

This package does not declare an exports field, so the exports above have been automatically detected and optimized by JSPM instead. If any package subpath is missing, it is recommended to post an issue to the original package (gzip-js) to support the "exports" field. If that is not possible, create a JSPM override to customize the exports field for this package.

Readme

Intro

gzip-js is a pure JavaScript implementation of the GZIP file format. It uses the DEFLATE algorithm for compressing data.

Please note that since this is a pure JavaScript implementation, it should NOT be used on the server for production code. It also does not comply 100% with the standard, yet.

The main goal of this project is to bring GZIP compression to the browser.

API

There is only one function so far, zip:

function zip(data[, options])

  • data- String of text or byte array to compress
  • options- object with options; options include:
    • level- compression level (1-9); default 6
    • timestamp- UNIX timestamp (seconds); if omitted, the current time will be used
    • name- optional; original name of the file

Sample usage:

var gzip = require('gzip-js'),
    options = {
        level: 3,
        name: 'hello-world.txt',
        timestamp: parseInt(Date.now() / 1000, 10)
    };

// out will be a JavaScript Array of bytes
var out = gzip.zip('Hello world', options);
