prerender-cache-auto-refresh v1.0.3

prerender-cache-auto-refresh

The plugin is currently in development

Prerender plugin for level caching, to be used with the prerender node application from https://github.com/prerender/prerender.

How it works

This plugin will store all prerendered pages into LevelDB.

How to use

In your local prerender project run:

$ npm install prerender-cache-auto-refresh

Then in the server.js that initializes the prerender:

server.use(require("prerender-cache-auto-refresh"));

Features

Ttl

It uses a default ttl of 2 months, but that can be overridden by setting a different value in prerender server.options.ttl.

Refresh

You can force a refresh from another plugin by setting req.refresh = true

Exemple:

// in another plugin placed before prerender-cache-auto-refresh
module.exports = {
  requestReceived: (req, res, next) => {
    req.refresh = true;
    next();
  },
};

Alternatively, you can delete the cache directly in the LevelDB database, using a tool such as lev2.

Level-party

The plugin uses the level-party module to get over the level multi-process restrictions.
