Requirements

• Docker

Usage

Pull and run the image:

docker pull microlc/micro-lc-prerender
docker run -p 3000:3000 microlc/micro-lc-prerender

Prerender will now be running on http://localhost:3000. Try the container out with curl:

Prerender plugins

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

• blacklist
• httpHeader
• removeScriptTags

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 microlc/micro-lc-prerender

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 microlc/micro-lc-prerender
