Death to Static Websites

All too often, web developers start a web application or website with a framework like Express, Rails, or ASP.NET MVC. For a time, they were necessary, but their time and usefulness is quickly expiring. In this post, I will make the argument for why you should not use these frameworks for the next great web application and instead use simpler websites based on a mix of static and dynamic HTML and web APIs.

This isn’t my first blog. This blog has been my home since 2012 when I learned about GitHub Pages and decided to give it a try. Previously, I have tried WordPress, BlogEngine.NET, and others. They worked fairly well, I blogged happily for a while, then I eventually stopped using them. While they were great as blogging engines and I was a successful blogger, I determined that being a successful blogger was not all that I wanted.

The problem, I determined, was that the blog engines were all successfully built on various web technology. WordPress is a lot of PHP, a language that I don’t know that well. I could probably learn it if I put the effort in, but to date I haven’t had much of a need to learn PHP. BlogEngine.NET was built on .NET, which pays my bills on a daily basis. But my problem with BlogEngine.NET was that I had a hard time diving into the code to learn how it works and I didn’t want to put in the effort to make changes that I wanted to make to fill the holes that I perceived that the blog engine had.

I also tried big content management systems like Umbraco. I was very successful with Umbraco and I liked the flexibility that it gave me, but in the end, changing or getting into the mindset of contributing to the core development, I decided that I just didn’t have the time. I wrote a few extensions, but I just didn’t want to build older-style ASP.NET applications. I was more into MVC at the time.

What I liked about GitHub Pages was the framework. Jekyll is a Ruby application that produces static websites given basic content. The static website is then uploaded and hosted on GitHub’s web servers. At first, the static website feature worried me, but I found freedom and satisfation creatively in my blog because there was not much there except for generating static content. It was easy to produce blog posts using Markdown, which I appreciated. I no longer needed a special editor like Windows Live Writer to write my posts and upload them to the blog site. A simple text editor will do.

Creatively, I liked that although I was still using Jekyll, the entire website was my creation. I defined the HTML structure. I defined the CSS. I didn’t have to fit into the constraints of an existing framework. I could choose to use other frameworks like Bootstrap if I wanted to. I could use tools like Less. I could tinker and play with the website and make it an invention of what I wanted it to be, which was very exciting for myself creatively.

The part that worried me was the static part of static websites on GitHub Pages. I worried that I was going to miss things that I could do in a server-side application that I couldn’t do in a static website. I worried that I would feel limited by the client-side only approach to developing. But fortunately, technology caught up in the form of newer web browser features and those concerns became less of an issue over time.

The modern web is in a wonderful place. We have excellent web browsers that are constantly pushing the envelope in making web applications more feature rich by the day. The Internet speeds are very fast and getting faster as cable providers are introducing gigabit Internet speeds to homes and businesses. Mobile browsers are exceptional. There are modern frameworks that make creating responsive applications so incredibly easy. It’s no longer necessary to run a separate mobile website to accommodate devices such as iPhones or iPads.

Another great technology that I feel is just starting to see its potential is something call Cross-Origin Resource Sharing or CORS. If you’re not familiar with CORS, it’s a mechanism for client side code from a website to safely invoke web service APIs from another service accessible over the Internet. It is meant to obsolete and replace technologies such as JSONP that allowed JavaScript code to be injected into web pages dynamically at runtime.

CORS is an extension to the HTTP protocol that allows a web service to indicate if a client appliation is authenticated and allowed to make HTTP requests to the web service’s APIs. Most importantly, CORS is supported by all major web browsers.

The great thing about CORS is that CORS makes static websites not so much static anymore. Using simple cloud technologies, static websites are just as capable as their server-generated peers, but might just be a bit easier and more flexible to develop.

An Example

With a little bit of CORS magic, I am going to accomplish a first for me: I am going to turn a blog post into an actual web application. This blog post is hosted by GitHub Pages and the page that you are reading now was generated using Jekyll. The original content was written in Markdown with a few HTML elements thrown in. You can see the code for the post in my public repository at

The web application that I am going to build is just going to be a simple form that accepts your name. When you enter your name and press the submit button to submit the form, client-side JavaScript will execute in your web browser that will invoke a CORS-enabled web API that will simply return a welcome message to you. The welcome message will then be displayed in the form. For full disclosure, I am going to use jQuery to implement the client-side form application. I will also be using CoffeeScript to write the source code for the web application. I use Grunt to build the website before I publish it to my GitHub repository, and I will use Grunt to transform the CoffeeScript source code into JavaScript.

Here’s the web application:

The source code for the form is below:

<form id="example-app">
  <div class="form-group">
    <label for="firstName">First name</label>
    <input type="text"
           placeholder="Enter your first name"
  <div class="form-group">
    <label for="lastName">Last name</label>
    <input type="text"
           placeholder="Enter your last name"
  <button type="submit" class="btn btn-default">Submit</button>
<div class="alert alert-success hidden">
  <p id="welcomeMessage"></p>

The application is simple. The user will enter a first name and a last name into the form, then press the Submit button. This will execute the JavaScript (or CoffeeScript) code that is behind the form to submit the user’s name to the web service, and the welcome message will be returned. When the welcome message is returned, the message will be output to the welcomeMessage paragraph element.

Here is the CoffeeScript code that reacts to the form and calls the remote web service:

$(document).ready ->
  $('#example-app').submit (event) ->
    userData =
      firstName: $('#example-app input[name=firstname]').val()
      lastName: $('#example-app input[name=lastname]').val()
      url: ""
      type: "POST"
      data: JSON.stringify userData
      contentType: "application/json"
    .done (data) ->
      console.log data
      response = JSON.parse(data)
      $('#welcomeMessage').text response.greeting
      $('#welcomeMessage').parent().removeClass "hidden"
    .fail (xhr, status, err) ->
      console.log err

When the form is submitted, the code will intercept the submit event for the form. The event handler will capture the first name and the last name that were entered into the form and will create a new JavaScript object containing those values. The event handler will then use jQuery to send an HTTP POST request to the web service that is hosted at, passing the JavaScript object as a JSON object. When the call is successfully handled, the done handler will be invoked which will store the welcome message in the welcomeMessage HTML element.

To complete this solution, I need a web service. For this example, I am going to build the web service in Go and will host the web service in a Heroku application.

Here is the source code for the web service:

package main

import (


func main() {
  port := os.Getenv("PORT")
  log.Println("Listening on port ", port)

  log.Fatal(http.ListenAndServe(":"+port, nil))

type welcomeRequest struct {
  FirstName string `json:"firstName"`
  LastName  string `json:"lastName"`

type welcomeResponse struct {
  Greeting string `json:"greeting"`

func sayHello(w http.ResponseWriter, r *http.Request) {
  body, err := ioutil.ReadAll(r.Body)
  if nil != err {
    log.Println("ERROR: ", err)
    http.Error(w, err.Error(), http.StatusInternalServerError)

  var request welcomeRequest
  err = json.Unmarshal(body, &request)
  if nil != err {
    log.Println("ERROR: ", err)
    http.Error(w, err.Error(), http.StatusInternalServerError)

  var response welcomeResponse
  response.Greeting = fmt.Sprintf("Welcome %s %s!", request.FirstName,
  data, err := json.Marshal(request)
  if nil != err {
    log.Println("ERROR: ", err)
    http.Error(w, err.Error(), http.StatusInternalServerError)

  _, err := w.Write(data)
  if nil != err {
    log.Println("ERROR: ", err)
    http.Error(w, err.Error(), http.StatusInternalServerError)

Now give it a try. Go back to the form and enter your name or someone else’s name. When you click on the submit button, the reqeust will be sent to the web server running in Heroku and a response will be returned. If you are using Google Chrome, open the Developer Console and watch the web request be sent. My static website now has the ability to display dynamic content, and no server-side framework such as ASP.NET MVC or Rails was used. Everything was rendered in the web browser, and a web API on a remote server performed data manipulation for my website.

Why I Like Static Websites

I demonstrated that using CORS, JavaScript, and a web API, I could add a bit of dynamic functionality and processing to an otherwise static website. Why is this important? Why would I still not use something like ASP.NET, Express, or Rails to build a website or web application?

The answer is that you can, but it’s not fully necessary in a lot of circumstances. If you have a mostly static website, say a corporate website, that has a few interactive features such as a contact form or a career application that is part of your website, you don’t need to use a complex framework like ASP.NET MVC that relies on server-side rendering. All of this can be achieved on the client.

When you utilize client side features using JavaScript and HTML, you effectively have a static website. The advantages of a website built with client technologies and supported by a web API is some very cool deployment options.

For example, if you have mostly static content with dynamic content that is driven with JavaScript on the client, you can use cheap cloud technologies such as Amazon Web Service’s S3 service for storing and serving your website. There is no need to run a web farm on the Internet. You only need to pay for the storage fees for storing your website content and the bandwidth for serving the content. S3 makes a great container for hosting websites.

The second great advantage is CDN deployment. A CDN, or content delivery network, is a set of edge servers that are deployed around the world. By combining AWS CloudFront with S3, you can increase the speed at which your website is downloaded by serving your content from the CloudFront edge servers around the world. Your website will appear faster and more response for your customers and users no matter where the user is located.

A third great advantage is SSL. Google and other search engines are starting to provide search optimization points for websites that are served via SSL. If you use server-side technologies and use a cloud hosting service to serve your website, you may have issues or extra costs for serving SSL content and associating a custom domain with your website. With Amazon CloudFront, you don’t have those costs. You can associate a domain with your S3 buckets and CloudFront edge locations, and you can also associate an SSL certificate with the CloudFront servers, all at no additional cost.

What We Learned

The goal of this post has been to make an argument that using modern web technologies including JavaScript and CORS, static websites do not have to be so static and websites that traditionally needed complex server-side architectures may not necessarily need them anymore. Thanks to advances in JavaScript and CORS for calling web APIs from web browsers, services that required technologies such as ASP.NET MVC or Express can now be accomplished using pure web technologies.
