![]() It also does not require you to write much of custom JavaScript code. Hotwire name basically is an abbreviation for `HTML Over the Wire`, which means sending generated HTML instead of JSON from the server to the client. Keeping rendering on server side makes your development experience simpler and more productive. Hotwire is an alternative approach to building SPA like web apps, rendering all of the HTML server side using Rails templates, while keeping the app fast and responsive. As you probably know there's a whole lot of complexity of building, maintaining and deploying two separate apps with interchangeable data.īut what if you could build an SPA without all that complexity of building two separate apps and writing lots of JavaScript code? Here's what Hotwire can help you with. With this approach, frontend is a separate application which sends AJAX requests to the Rails server, and Rails is being solely a JSON API. And it works nice, the only downside is that it's mixing server side rendering and client side rendering on a page.Īnother, more traditional way these days, is going all in and using React, Vue or another JS framework on the frontend to use only client-side rendering, i.e., so-called Single Page Application (SPA). Then frontend framework transforms received JSON to DOM elements and updates DOM to reflect those changes. So, JS component sends an AJAX request and Rails server responds to it with JSON data. Then we can get to some JS components on the frontend (e.g., using React) to make an app feel even more responsive. And Rails responds with generated JS code, which then is executed by the browser to dynamically update those parts of the page. But it still is replacing the whole body, not only changed parts of the page.īut what if you want to reload only parts that changed? Well, you could use Rails AJAX helpers, when you mark some elements as data-remote='true', which makes those element sending AJAX GET/POST requests instead of regular GET/POST requests. No stylesheets or scripts reloading, which means a faster page navigation. It then merges the head tag of the fetched page and replaces the whole body tag of the page, so there is no full page reload. What Turbolinks are doing for "responsiveness" of Rails? Turbolinks intercept all link clicks and instead of sending regular GET request, it sends asynchronous JavaScript request (AJAX) to fetch HTML. ![]() On June 25, 2013, Rails 4 was released introducing Turbolinks.
