Server-side rendering

Getting started

Download the jsblocks-seed project and run the commands below:

npm install

npm run node

Understanding server-side rendering basics

var blocks = require('blocks');

// creates the server which will automatically handle server-side rendering

Creating a blocks.server() does couple of things:

  • creates an express app listening to the specified port (default 8000)
  • expects an app folder where to place index.html file which will be the main application view
  • register a middleware which handles all requests and servers all routes that you have created in your client-side code
  • when a route is satisfied it renders the page executing your client-side application logic on the server


var blocks = require('blocks');
var server = blocks.server({
    // the port at which your application will be run
    port: 8000,

    // the folder where your application files like .html, .js and .css are going to be
    // the value is passed to express.static() middleware
    static: 'app',

    // caches pages result instead of executing them each time
    // disabling cache could impact performance
    cache: true,

    // provide an express middleware function or an array of middleware functions
    // use: [compression(), bodyParser()]
    use: null

// returns the `express` app `blocks.server` is using internally
var app =;
