prerender-multidomain-disk-cache v2.0.2

prerender-multidomain-disk-cache

This is a plugin for prerender.io providing caching on disk. It is a fork of legalnavigator/prerender-disk-cache.

Requires:

• node >= 4.0
• prerender >= 5.0.0

How it works

This plugin will store all prerendered pages into a filesystem hierarchy including the server host name. For example:

• url http://www.domain.com/?escaped_fragment=/en/about - will be saved in CACHE_ROOT_DIR/www.domain.com/en/about/perender.cache.html
• url http://www.domain.como/en/about?escaped_fragment= - will be saved in CACHE_ROOT_DIR/www.domain.com/en/about/perender.cache.html
• url http://www.domain.com/?escaped_fragment=/en/main/path/blah - will be saved in CACHE_ROOT_DIR/www.domain.com/en/main/path/blah/perender.cache.html
• url http://www.domain.com/en/main/path/blah?escaped_fragment= - will be saved in CACHE_ROOT_DIR/www.domain.com/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-multidomain-disk-cache --save

Then in the server.js that initializes prerender:

server.use(require('prerender-multidomain-disk-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)
