Prerender plugins

A few default plugins have been activated by default (see server.js):

This can be modified by creating your own server.js and mounting this file as a docker volume:

docker run -p 3000:3000 -v $(pwd)/server.js:/home/node/server.js tvanro/prerender-alpine:6.5.0 

Prerender memory cache

The prerender-memory-cache plugin is not activated by default. You can activate it with the environment variable MEMORY_CACHE=1.

You can customize cache behavior with environment variables :

  • CACHE_MAXSIZE=1000 : max number of objects in cache
  • CACHE_TTL=6000 : time to live in seconds
docker run -p 3000:3000 -e MEMORY_CACHE=1 -e CACHE_MAXSIZE=1000 -e CACHE_TTL=6000 tvanro/prerender-alpine:6.5.0
