prerender-redis-cache-gzip

============================

Prerender plugin to cache (redis) compressed html, to be used with the prerender node application from https://github.com/prerender/prerender. This was highly influenced by https://github.com/JonathanBennett/prerender-redis-cache

How it works

This plugin stores pages returned through prerender in a redis instance. Currently, it caches the pages for 1 day then expires them. This can be overridden by specifying the env variable “process.env.PAGE_TTL” in seconds. To never expire you should set the PAGE_TTL variable to 0.

How to use

In your local prerender project run:

$ npm install prerender-redis-cache-gzip --save

Then in the server.js that initializes the prerender:

server.use(require('prerender-redis-cache-gzip'));

Configuration

By default it will connect to your Redis instance running on localhost and the default redis port with no authentication, and the default database number (normally 0). You can overwrite this by setting the REDISTOGO_URL, REDISCLOUD_URL, REDISGREEN_URL or REDIS_URL (in the format redis://user:password@host:port/databaseNumber). This currently covers all heroku add-ons for Redis to support quick start.
