Why Use React JS for Fast Interactive User Interfaces? — SitePoint

  • The Virtual DOM is at the core of what makes React fast at rendering user interface elements and their changes.
  • Each time there are changes to the underlying data in a React app, React creates a new Virtual DOM representation of the user interface.
  • This is where efficient diff algorithms, batching DOM read/write operations, and limiting DOM changes to the bare minimum necessary, make using React JS and its Virtual DOM a great choice for building performant apps.
  • Our First 50,000 Stars — Vjeux

    Although some would argue that all projects need React JS, I think it’s uncontroversial to say that React would be a great fit for web apps where you need to keep a complex, interactive UI in sync with frequent changes in the underlying data model.

    If you’re curious about how React JS and its Virtual DOM work, here’s where you can learn more:

    Conclusion
    React JS and other similar JavaScript libraries ease the development of snappy, event-driven user interfaces that are fast at responding to state changes.

Maria Antonietta Perna discusses what makes React JS a great fit for building fast UIs and introduces the concept of the Virtual DOM and how React uses it.

Learning React and React-Native – Jorge Rubiano – Medium

Learning React and React-Native  #react #learning #reactnative #reactjs #reactjs

  • Learning React and React-NativeExample APP React-nativeIn this article I want to show you about my learning experience using the technologies: “React” and “react-native”, in this moment I am not an expert in this topic, but I am convinced the best option for learning is to create something.Shots — Game ES6I heard about react in the past year (2016), in that year I followed the new technologies and standards in Javascript, learning about ES6, how to configure a basic environment with npm scripts, in this case I used this environment to develop simple games with ES6 and use new technologies such as Service WorkerI decided to start learn react, At first to me was complicated because I had never used webpack, the majority of tutorials I followed need configure this tool initially.Fortunately in this year emerged create-react-app, with this module is very easy to start a project with react, this module configure the environment for you.With create-react-app developed my first “Hello World”, the process was very easy, even the browser makes automatic updates, I think this is “Awesome”.
  • I read articles and saw videos about react, later I decided search a course, It called my attention “react for beginners” by Wes Bos, I learned other topics in courses the Wes Bos for example Flexbox, then I decided to take that course (React for Beginners).
  • Example Project course.The project we develop in this course is called “Catch of the day”, we not only learned about react but also firebase, in this course I understood about the JSX, state, props, components, routing, fetch data and other topics.For me this course is a good introduction to learn react, in this course we not use redux or other libraries to manage the state.Personally I liked React because I use ES6 in the process, for example .
  • reducer, arrow functions and other features , I know there are other fantastic frameworks for example AngularJS/Angular or libraries such as VueJS, At this moment for my work React is the perfect tool.

In this article I want to show you about my learning experience using the technologies: “React” and “react-native”, in this moment I am not an expert in this topic, but I am convinced the best option…

My Experience With Progressive Web Apps – Renganatha Arunachalam – Medium

My Experience With Progressive Web Apps  #webpack #progressivewebapp #react #reactjs

  • They are the future.I built a Progress Web App of WhatsApp Web using Webpack 2.0, React and Express.Note: This is not a complete clone of WhatsApp Web but minimal one to have an understanding of how to create a PWA app.Case StudyMain aim of PWA apps should be making the load time of webapp faster.Server Side RendingServer Side Rendering (App shell architecture) is a way of making the load time faster without JavaScript .
  • Sample Code of match api from react-routerBundlingVarious ways are available to bundle the app with minimum size using Webpack.I say separating the vendor libraries and components is the best way to reduce the bundling size.
  • The remaining two bundles are precisely due to code splitting.react-router can be used for Route based splitting out of box with WebpackWorkers From WebWeb workers and Service workers are most useful feature from web.
  • Both the workers have no access to DOM.Web Workers are use to do heavy operation in separate thread of browser and return result to the web app.Service workers are useful for caching the request.
  • All three attributes are used for loading the scripting without blocking onLoad function.Use Web manifest.json to have Native feel when users does Add to Home Screen in Mobile.Use LightHouse Chrome extension to validate your websiteUseful ArticlesProgressive web app with with React.js — Four LiteUber ClonePrefer defer over AsyncGetting most out of CommonChunksPluginVendor and Code Splitting in WebpackUseful webpack pluginsThe Offline CookbookHttp Browser Caching

Introduction to Progressive Web Apps with React.js with George Chen

  • Progressive web apps (PWA) use the latest web technologies to create native-like performance and user experiences.
  • By implementing PWA, businesses such as Google, AliExpress, and FlipKart have observed a 50-100% increase in retention and conversion rates.
  • In this presentation we will learn the core concepts of PWA such as service worker, app manifest, and push notification.
  • We will also look at how to use these exciting technologies to add offline capabilities to a React.js app as well as improve its speed and performance.
  • He enjoys learning new technologies and sharing findings with the community.
