sportihome-prerender-filesystem-cache v1.0.0

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

How it works

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

How to use

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'));

Configuration

Optionally, define some env variables:

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

• CACHE_ROOT_DIR defaults to os.tmpdir()/prerender-cache
• CACHE_LIVE_TIME defaults to 3600 (1 hour)
