1/3/2024 0 Comments Rails 7 react![]() Let's create our first component by running the following command in our console rails g react:component HelloWorld greeting:string Now let's link the Javascript pack in Rails view using javascript_pack_tag helper: This gives us a components directory under app/assets/javascripts/, a manifest file and adds them to our application.js's dependency. Run the generator rails webpacker:install Install the added gem, by running bundle install We can start by adding the gem to our dependencies: #Gemfile So to begin with let's create our rails app (assuming you already have rails framework installed on your PC) rails new react-rails-app Webpack is a popular JavaScript bundler built on top of Node.js. In order to make it work with rails versions lower than 4.2, you have an option of either using an asset pipeline or have to do some workaround on setting webpack.īefore moving on let's learn about Webpack in brief. This gem supports rails version greater than 4.2 because webpacker gem does not support rails versions lower than 4.2. Lets you use JSX, ES6, TypeScript, CoffeeScript.It automatically renders React server-side and client-side.Some of the features of using react-rails gem are: React can be integrated with Ruby on Rails in many ways, but we suggest official react-rails gem which is the simplest way to get started with React and JSX in a Rails application. ![]() Part-I: Integrating React with Ruby on Rails In the first part of this article, we will discuss how to integrate React with Ruby on Rails application and in the second part, we will discuss common challenges we might face during integration. We can pass properties to the component, as soon as the property gets changed, the component automatically gets re-rendered, which results in improving the performance of the page by reducing the API calls. It can be considered as the "V" of the " MVC" architecture. React creates a virtual DOM, which helps in fast rendering and handling the state changes with ease without interfering with the actual DOM. ![]() Component logic is written in JavaScript instead of templates, you can easily pass rich data/properties through your app and keep the state out of the DOM. React enforces component-based structure of building UIs. Its declarative views make the code predictable and easier to debug. React is a JavaScript framework (developed by Facebook) which is most widely used for creating interactive UIs. ![]() They provide robust abstraction & intuitive APIs to work with while providing a great developer experience. Another major concern is an actual refresh/reload of the page while navigating from one page to another, this induces the assets to be loaded again and again which makes the webpage slow and non-interactive.įrontend frameworks are great when it comes to solving these above-mentioned problems. Keeping track of multiple elements, dealing with multiple UI states, updating UI based on user interaction while keeping business logic in check is a tough problem to deal with. On the frontend side of things, building snappy & reactive UIs can be challenging as DOM manipulation using plain-vanilla JavaScript and jQuery can be a snag at times. All these characteristics make Ruby on Rails a near perfect choice of framework for businesses & startups. One can also say that its an extremely productive technology stack that enables quick development with easy deployment. ![]() Ruby on Rails has been one of the most versatile and most widely used technology for creating a fast-paced application. 7 min read Gracefully integrate Reactjs with Ruby on Rails in SaaS Applications. ![]()
