![]() It works both on the client and on the server with Node.js, so that you can also use server-side rendering. Our applications become less buggy and easier to maintain. The good news is React does this for you in an optimized way to minimize unnecessary re-renders. It also decouples data from the view so that updates can be batched or done asynchronously. One-way data flow ensures that the state remains the single source of truth for a component tree. In React, the markup and click event are both in the same JavaScript file: For example, we might have a button with a click event. Often, we put the style there too, but this isn’t required. In other words, we put both the structure (markup) and behavior (events, etc.) in one place. In React, we write one full representation of a view. In the next section, you’ll see how developing components is easier with one representation of a view. React takes this one step further with more flexibility, ease of developing and modifying, and composition of applications from components. Pattern Lab and Emulsify have made atomic design easier in Drupal through the use of "living" style guides. Components are similar to Drupal or Twig templates in that they can be reused with different sets of data through variables, and assembled into a tree of layouts and elements. Each of these atoms can receive data and have their own state, creating a powerful set of UI building blocks. We refer to this as the component hierarchy. Developers write reusable components, starting at the "atomic" level, and work their way up to collections of atoms, layouts, and screens. How does all of this relate to React? React is a component-based system of building user interfaces (UI). This is how Drupal core and most web development currently works.Ītomic Design, a design-systems methodology outlined by Brad Frost, states that we should start with the basic building blocks, or atoms, of a page and work our way up to create designs: We then took those designs and broke them down into their containers, grid systems, and elements to write our markup. Most of us have probably worked with top-down designs provided by page and screen. Finally, with React you can use other non-Drupal services to extend the features of your application. Secondly, it can provide more complex user experiences that are also more performant. One of the biggest reasons to use React is that it makes building the front end immensely easier than Drupal theming. The REST API in Drupal 8 Core, the JSON API module, and the GraphQL module all have made implementing React on a decoupled Drupal backend easier. You can also embed it directly in your Drupal front end, and pick and choose parts of your application to convert - much the same way you might use jQuery with Drupal right now. One is as a stand-alone front-end application that uses API endpoints from your Drupal app, as a headless CMS. You can implement React in multiple ways. In a typical Drupal site a React front-end would replace your theme layer. If you’re familiar with the MVC framework, it’s really only the V, or view. But first, what is React? React is a JavaScript library for building user interfaces. We’ll also talk about how some of the concepts are similar or different from the Drupal and PHP world. ![]() In this article, we will give you a taste of why developers are so happy with React. Those are the highest percentages among all frameworks surveyed, including Angular 1 and 2, Vue, Backbone, Polymer, Ember, and others. According to the State of JavaScript, in 2016, 92% of developers who had used it before would use it again, and that number rose to 93% in 2017. Why is that? One of the primary reasons is developer happiness. Even with all this churn, React has won the front-end race for a few years now. Blink and you may miss the next big thing. The JavaScript ecosystem notoriously churns out new frameworks and libraries seemingly on a weekly basis. 8 Things to Know About React for Drupal Devs ![]()
