Hotwire: A Magic in Ruby on
Rails World
Imagine a web app that feels quick and responsive, like magic! That's
the objective of Hotwire Rails. Instead of tons of confusing JavaScript
code, Hotwire Rails relies on the server to do more work, keeping
things simple. When you click a button on a website, the whole page
reloads. Hotwire Rails makes it so only the part that changes needs to
refresh, enhancing the user experience in web application
development. This approach is easier to learn and write, so you can
focus on building cool features instead of wrestling with complex
code.

As web applications continue to evolve, embracing Hotwire web
development positions your projects for success. By prioritizing
speed, responsiveness, and simplicity, you can create applications
that stand out in today’s competitive digital landscape.
What is Hotwire?
Hotwire is an approach to building web and mobile applications by
sending HTML over the wire. It itself isn't a single framework, but
rather
a collection of tools designed to work together. You can use Hotwire,
wherever you want to add interactivity to your application. When you
want to display/hide content conditionally based on user ’ s interaction
or to update some content in real-time.
Hotwire Components:
As mentioned before, Hotwire is a collection of tools for building web
applications. It includes three main components:
1. Turbo:
This is the workhorse of Hotwire, particularly with its Rails Turbo
capabilities, responsible for speeding up page interactions. It provides
techniques to handle HTML data coming over the wire and display it
on the application without performing a full page reload. Furthermore,
it achieves this through features like:
● Turbo Drive □ Handles seamless partial page updates without full
reloads, keeping your application feeling snappy.
● Turbo Frames □ Targets specific areas of the page for updates,
minimising unnecessary DOM manipulation.
Turbo Streams □ It enables real-time updates to your applications,
without reloading the page. Keeping your data fresh.
Now, Let's walk through a simple Turbo example:
Turbo Frames allow you to update only part of a page when a user
interacts with it. Here’s an example of updating a frame i.e. my-frame,
without a full page refresh:
In this example, clicking the link triggers Turbo to load content from
'frame_path' into the 'my-frame' without reloading the whole page.
Take another example. You can use Turbo Streams to push real-time
updates to the client. Here's how you can create a chat application
where new messages appear without reloading:
In this case, each new message is appended to the messages div
using turbo-stream, allowing real-time updates without needing to
refresh the page.
Turbo Action List
Turbo actions define how your application should interact with the
server-side responses:
● replace□ Replaces the content within a Turbo Frame.
● append□ Adds new content to the end of an existing section.
● prepend□ Inserts content at the beginning of an existing section.
● update□ Modifies content within an element.
remove□ Removes an element from the DOM.
2. Stimulus:
A lightweight JavaScript framework for handling user interactions. It
uses controllers and targets to define how your application responds
to user input. By leveraging Hotwire Stimulus Rails, you can build fast,
dynamic applications with minimal JavaScript, using attributes like
data-controller, data-action, and data-target on page
elements to handle interactions efficiently.
3. Strada:
Strada is an upcoming addition to the Hotwire suite, aimed at
enhancing hybrid mobile app development. It provides native-like
controls and interactions with minimal JavaScript, ensuring web-
driven hybrid apps maintain performance.
Lazy Loading with Turbo Frames:
Lazy loading is a performance technique that allows you to load
content only when needed, often improving user experience by
delaying the loading of offscreen or secondary content. With Turbo
Frames, lazy loading can be achieved by wrapping the content you
want to load later in a frame and setting it to load via user interaction.
Example for lazy loading with turbo frames:
Here, the content within the frame will load only when the frame is
requested, either by navigating to it or via user interaction like clicking
a button.
Benefits of Using Hotwire Rails:
Hotwire Rails offers several advantages for developers seeking to
streamline their workflow and create high-performing web
applications. Here's a breakdown of its key strengths:
I. Less Code, More Action: Hotwire Rails lets you build dynamic
features with way less JavaScript. This means you can focus on the
important stuffs and write less code overall.
II. Speedy Apps: Hotwire Rails keeps your app feeling fast by only
updating parts of the page that need it. No more waiting for full
reloads just smooth sailing for your users.
III. Search Engines Love It: Since Hotwire Rails uses server-side
rendering, search engines can easily understand your content. This
means your app is more likely to show up at the top of search results.
IV. Clean and Organised: Hotwire Rails keeps your code nice and tidy
by separating what happens on the server (server stuff) from what
happens on the user's screen (client stuff). This makes your code
easier to understand and maintain.
Comparison to Similar Technologies:

https://hotwired.dev/
There are several other technologies that are similar to Hotwire,
including React, Vue.js, and Angular. These technologies are also
designed to make it easier to build interactive, reactive web
applications.
1. Hotwire is designed to be used with the Ruby on Rails
framework, whereas React, Vue.js, and Angular are more
general-purpose and can be used with any web development
framework or language. This means that if you ’ re already using
Rails, Hotwire may be a more natural fit for your project than
these other technologies.
2. Hotwire uses “ partial replacement ” technique to update specific
parts of the page without having to reload the entire page. This
means that you can update the page just by rendering a view or
redirecting to a different action.
Conclusion:
Hotwire Rails represents a shift towards a more efficient and server-
centric approach to web development. By leveraging the power of
HTML over the Wire □HOT□, Hotwire allows you to build dynamic and
interactive applications without the burden of heavy JavaScript
frameworks.
