NPM version Build Status Dependency Status

connect-gzip-static

Middleware for connect: serves compressed files if they exist, falls through to connect-static if they don't, or if browser does not send 'Accept-Encoding' header.

You should use connect-gzip-static if your build process already creates compressed (using gzip or brotli) files. If you want to compress your data on the fly use built-in connect compress middleware. And if you want to compress your files dynamically you may want to look up connect gzip.

Installation

  $ npm install connect-gzip-static

Options

gzip-static is meant to be a drop in replacement for connect static middleware. Use the same options as you would with connect static.

Usage

var gzipStatic = require('connect-gzip-static');
var oneDay = 86400000;
 
connect()
  .use(gzipStatic(__dirname + '/public'))
 
connect()
  .use(gzipStatic(__dirname + '/public', { maxAge: oneDay }))

How it works

We start by locating all compressed files (ie. files with .gz and .br extensions) in root directory. All HTTP GET and HTTP HEAD requests with Accept-Encoding header set to gzip are checked against the list of compressed files and, if possible, fulfilled by returning the compressed versions. If compressed version is not found or if the request does not have an appropriate Accept- Encoding header, the request is processed in the same way as standard static middleware would handle it.

Debugging

This project uses debug moudle. To enable the debug log, just set the debug enviromental variable:

DEBUG="connect:gzip-static"
