Prerender In-Memory Cache plugin

This is a plugin meant to be used with your Prerender server to cache responses in memory.

Run this from within your Prerender server directory:

$ npm install prerender-memory-cache --save

server.js

const prerender = require('prerender');
const server = prerender();

server.use(require('prerender-memory-cache'))

server.start();

Test it:

curl http://localhost:3000/render?url=https://www.example.com/

Accessing that URL twice should render the page the first time and then serve it from the in-memory cache on the second request.

Options

CACHE_MAXSIZE

Maximum number of items in the cache.

export CACHE_MAXSIZE=1000

default: 100

CACHE_TTL

Time to live for items in the cache (in seconds)

export CACHE_TTL=600

default: 60
