![]() Turbo will intercept your links and forms.Regardless of whether the server provides a full document, or just a fragment containing an updated version of the requested frame, only that particular frame will be extracted from the response to replace the existing content. Any links and forms inside a frame are captured, and the frame contents automatically updated after receiving a response. ![]() Turbo Frames allow predefined parts of a page to be updated on request. Here’s the explanation of what a Turbo Frame is, from the Turbo manual: Importantly, our Rails app is now made up of turbo-frames, that look like this: Turbo Rails is a collection of Javascript that operations behind the scenes and also an implementation of pattern for how Rails responds to requests on the backend To find out my about this, see Option B in my Rails Heart React Series.) However, I am very careful to make sure to separate my React parts from the Turbo Rails interactions and it takes more work. (For my apps, sometimes I build do build some sections of the app in React while still using Turbo Rails for the primary navigation. In this lesson, I will cover Turbo Rails, Hotwire, and Stimulus to set you up for success with Rails 7. You must know how it works or else you will be thrown off and get unexpected errors. Turbo Rails is an all-in solution that takes over all link clicks and forms on your website. Unless you want to split you app into different sections, I would not recommend mixing & matching React, Vue, Angular, etc with Turbo Rails. For these kinds of apps you might do best to consider a more data-centric frontend paradigm. For these apps, you need the data to be very close to the user, and you want to harness that fact to build highly interactive or animated experiences. Also, apps that need specific animations between steps (like games). (Turbo Rails handles your transitions and the options are limited.)įor example: charts & graphs, interactive gaming experiences, super interactive/immersive VR experiences, highly immersive mobile or browser experiences. ![]() The kinds of apps that Turbo Rails will not be suitable for are apps which are necessarily data-heavy on the frontend or apps that require specific animations when flipping between views. ![]() These apps need a lot of quick user interaction that treats the client as a dumb terminal and leaves the view rendering to Rails. Paradigmatically, your business logic will remain on the server (primarily), and you won’t write much business logic into Javascript or the frontend layer. Most dashboard-like apps, apps like Facebook, Github, Shopify, Basecamp, etc will fly just fine using Rails Turbo. It’s either-or, and here’s my brief recommendation: It is not recommended that you mix these paradigms with Javascript-heavy frontends, like React, Angular, Vue, etc. Although Rails remains an excellent option for API-only backends (create your rails app with -api-only), Rails 7 major improvements are around the frontend and the new Turbo, Stimulus, and Hotwire paradigms. In this crash minicourse I’ll cover Rails 7 only, its major parts and key elements benefits, whats new, what’s changed, and why. However, it’s important when structuring a new Rails app to think about how much navigational control you will want to delegate to Rails’s Turbo system and/or how much you want to implement as a single-page app (for example, using a front-end routing system instead of Turbo). If you are using Rails as an API-only backend, this likely does not affect you. That means that Hotwire is the default way to implement a Rails app. HotWire and Turbo Rails are now first-class citizens in Rails.
