prerender-filesystem-cache

This is a plugin for prerender(.io) providing caching in the file system. It is a fork of https://github.com/suhanovv/prerender-file-cache, focussing on improved URI parsing, platform-independency and providing test coverage.

Version 2.0.0 has been tested to work with prerender version 5.4.x.

Requires node >= 4.0

Status

The version 1.0.0 of this plugin and all its hotfixes target the prerender phantomjs branch (version 4.4.x).

This plugin will store all prerendered pages into a filesystem hierarchy. For example:

url http://domain.lo/?_escaped_fragment_=/en/about - will be saved in CACHE_ROOT_DIR/en/about/perender.cache.html
url http://domain.lo/en/about?_escaped_fragment_= - will be saved in CACHE_ROOT_DIR/en/about/perender.cache.html
url http://domain.lo/?_escaped_fragment_=/en/main/path/blah - will be saved in CACHE_ROOT_DIR/en/main/path/blah/perender.cache.html
url http://domain.lo/en/main/path/blah?_escaped_fragment_= - will be saved in CACHE_ROOT_DIR/en/main/path/blah/perender.cache.html

The package is available on npm. Thus, in your local prerender project simply run:

$ npm install prerender-filesystem-cache --save

Then in the server.js that initializes prerender:

server.use(require('prerender-filesystem-cache'));

Optionally, define some env variables:

export CACHE_ROOT_DIR=/your/directory/for/cache  
export CACHE_LIVE_TIME=10000 (in seconds)
