gzippo Build Status

gzippo pronounced g-zippo is a gzip middleware for Connect / expressjs using node-compress for better performance, in node 0.6 and up will be using the new zlib api.

gzippo currently only supports only gzipping static content files however a release is in progress to introduce streaming support.

Notice

Please note that [email protected] branch will only be tested for nodejs 0.4, where as [email protected] will work for node 0.6

Installation

$ npm install gzippo

Usage

Static Gzip

In your express/connect server setup, use as follows:

var gzippo = require('gzippo');

//Replace the static provider with gzippo's
//app.use(express.static(__dirname + '/public'));
app.use(gzippo.staticGzip(__dirname + '/public'));

Options:

  • contentTypeMatch - A regular expression tested against the Content-Type header to determine whether the response should be gzipped or not. The default value is /text|javascript|json/.
  • maxAge - cache-control max-age directive, defaulting to 1 day
  • clientMaxAge - browser cache-control max-age directive, defaulting to 1 week
  • prefix - A url prefix. If you want all your static content in a root path such as /resource/. Any url paths not matching will be ignored

Currently the gzipped version is created and stored in memory. This is not final and was done to get a working version up and about.

Gzippo now uses the native Zlib support found in node >= 0.6

Streaming Gzip

Starting in Connect 2.X Expressjs has the ability to use a streaming gzip module provided natively by connect. As this 2.X branch is not currently stable I have back ported the compress.js component into gzippo.

app.use(gzippo.staticGzip(__dirname + '/public'));
app.use(gzippo.compress());

This has no caching and is currently unsupported as it will be included in a future connect 1.X release, up until then compress.js will be included in gzippo.
