    prerender-node-mongo

    Express npm plugin for MongoDB caching, to be used with the prerender-node middleware for prerender

    This was inspired by prerender-mongo and modified to work with Express apps. This also works with Meteor.

    How it works

    This plugin will store prerendered pages into a MongoDB database.

    Default values:

    mongoUri: mongodb://localhost/prerender // prerender being the database name
    ttl: 86400 // pages will be cached for 1 day
    collection: pages
    

    How to use

    In your local Express app run:

    $ npm install prerender-node-mongo --save
    

    Then in your app's server.js:

    // set up prerender-node
    let PrerenderNode = require('prerender-node');
    
    // set up prerender-node-mongo
    let PrerenderNodeMongo = require('prerender-node-mongo');
    
    // hook up the cache
    PrerenderNode.set('beforeRender', PrerenderNodeMongo.beforeRender);
    PrerenderNode.set('afterRender', PrerenderNodeMongo.afterRender);
    
    app.use(PrerenderNodeMongo);
    app.use(PrerenderNode);
    

    A custom mongo url can be set using env variables MONGOLAB_URI or MONGOHQ_URL.

    To change the page expiration use env variable PAGE_TTL.

    How to update stored cache

    Change the HTTP GET method to POST or PUT and prerender will re-cache it.

    Install

    npm i prerender-node-mongo
