Prerender plugin for Redis caching, to be used with the prerender node application from https://github.com/prerender/prerender.
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.
In your local prerender project run:
$ npm install prerender-redis-cache --save
Then in the server.js that initializes the prerender:
server.use(require('prerender-redis-cache'));
By default it will connect to your Redis instance running on localhost and the default redis port with no authentication. You can overwrite this by setting the REDISTOGO_URL, REDISCLOUD_URL, REDISGREEN_URL or REDIS_URL (in the format redis://user:password@host:port). This currently covers all heroku add-ons for Redis to support quick start.
- Slightly finer-grain error catching to make sure this plugin doesn't crash prerender for any reason.
- Make POST request to a URL clear the cache in line with a few other plugins
