Top 5 HTML-over-the-Wire Libraries for Modern Web Development
Introduction
HTML-over-the-Wire is an approach to web development that focuses on rendering HTML on the server and updating only the parts of the page that need to change, rather than rendering the entire page on the client side. This reduces the amount of JavaScript required, which can lead to faster page load times, better performance, and an overall improved user experience. HTML-over-the-Wire libraries are essential tools in modern web development, as they provide a lightweight and efficient way to build rich, interactive web applications without the need for complex client-side frameworks and libraries.
In this article, we will explore the top 5 HTML-over-the-Wire libraries for modern web development, their key features, and how to get started with each one. These libraries include Turbolinks, StimulusReflex, Phoenix LiveView, Unpoly, and HTMX. We will also discuss the advantages and limitations of each library to help you choose the best one for your project.
1. Turbolinks
Overview of Turbolinks
Turbolinks is a minimal JavaScript library created by the team behind Ruby on Rails. It was first introduced in Rails 4 and has since become a popular choice for developers looking to improve the performance of their web applications. The main goal of Turbolinks is to provide fast and efficient navigation between pages of a web application by replacing full page reloads with partial updates.
Key features of Turbolinks include:
- Fast and efficient navigation between pages
- Automatic handling of page updates and asset loading
- Built-in caching for improved performance
- Easy integration with existing applications
Turbolinks is an excellent choice for projects that need a lightweight solution to improve navigation performance and user experience, without the overhead of a full client-side framework.
How Turbolinks Works
Turbolinks works by intercepting clicks on links within your application and fetching the requested page via AJAX. Instead of loading the entire page, Turbolinks replaces only the <body> element of the current page with the <body> element of the fetched page. This results in a faster and more seamless navigation experience.
Turbolinks also includes built-in caching to further optimize performance. When a user navigates to a previously visited page, Turbolinks retrieves the cached version of the page, which can significantly reduce server load and improve response times.
In addition, Turbolinks handles asset loading and management, ensuring that CSS and JavaScript files are only loaded once, regardless of how many times a user navigates between pages.
Getting Started with Turbolinks
To get started with Turbolinks, you can install the library using npm or yarn:
npm install turbolinks
# or
yarn add turbolinks
Next, import Turbolinks into your JavaScript entry point:
import Turbolinks from "turbolinks";
Turbolinks.start();
With Turbolinks installed and initialized, you can now enjoy faster navigation in your web application. To further customize the behavior of Turbolinks, refer to the official documentation.
2. StimulusReflex

How StimulusReflex Works
StimulusReflex extends the capabilities of the Stimulus JavaScript framework by integrating it with Ruby on Rails and ActionCable, a built-in framework for real-time communication in Rails applications. When a user interacts with a StimulusReflex-enabled component, an ActionCable channel is used to send the event to the server, where the application state is updated, and the corresponding server-rendered HTML is sent back to the client. The updated HTML is then merged with the existing DOM, resulting in a seamless, real-time update.
By delegating state management and rendering to the server, StimulusReflex enables developers to build complex, interactive applications with minimal client-side code, leading to improved performance, easier maintenance, and a more streamlined development process.
Getting Started with StimulusReflex
To begin using StimulusReflex, first ensure that you have a Ruby on Rails application with ActionCable and Stimulus set up. Then, add the stimulus_reflex gem to your Gemfile and run bundle install:
gem "stimulus_reflex"
Next, install the stimulus_reflex npm package and import it into your JavaScript entry point:
npm install stimulus_reflex
# or
yarn add stimulus_reflex
import StimulusReflex from "stimulus_reflex";
import consumer from "./channels/consumer";
// Initialize StimulusReflex with your ActionCable consumer
StimulusReflex.initialize(application, { consumer });
With StimulusReflex installed, you can now create Reflex components by defining a Stimulus controller and corresponding server-side Reflex class. For more detailed instructions and examples, refer to the official documentation.
3. Phoenix LiveView
