Prerender plugin for Redis caching, to be used with the prerender node application from https://github.com/prerender/prerender.
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 --save
Then in the server.js that initializes the prerender:
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
REDIS_URL (in the format redis://user:password@host:port/databaseNumber). This currently covers all heroku add-ons for Redis to support quick start.
Thanks to the following for making branches with changes which were merged with the 0.2.0 release.
Fantastic Prerender team.
- 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
