express-renderer

Gives express the ability to render pages via phantomjs for SEO purposes.

installation

$ npm install express-renderer

use

after you instantiate your app you can use the middle-ware like this

app.use(require('express-renderer')({
    portPool: [18080,18081,18082,18083,18084], // required

    host: 'localhost:4321', // required

    userAgentMatch: function (userAgent) {
        return true;
    }

    // phantomOptions: ['--load-images=no', '--disk-cache=yes', '--web-security=no'],

    // log: true,

    // routeMatch: function () {
    // 	return true
    // }
}));

when a request fulfills the userAgentMatch, and the routeMatch the server will render the HTML

advanced

if your page needs additional async tasks to be completed you can specify a ServerRendering method that can return true when everything is ready:

window.ServerRendering = navigator.userAgent.match(/PhantomJS/);

if (window.ServerRendering) {
    window.ServerRenderingWaitFor = function () {
        return window.pageIsReady;
    };
}
