Ext JS to React: Class Instantiation and Code Style

  • Ext JS components are really just JavaScript functions which allow you to use the keyword: – – This means each class is native JavaScript.
  • Meaning, JSX enables you to outline not only the HTML and React component structure, but also call other JavaScript functions or even execute code statements right from within the JSX body.
  • Here is an example functional React component: – – This code sample highlights one of the major differences between Ext JS and React.
  • JSX is a very common strategy when creating React components.
  • Instead, each component is instantiated by React itself when you include the component class in returned JSX (i.e. in the example above).

React enjoys the benefits of the latest ECMAScript conventions (with some transpiling magic from Babel) along with JSX syntax. In the following sections, we will look at how Ext JS components are instantiated along with how a functional component is used in a React app. We’ll also review common coding styles that differ between the two ecosystems. Just a note before we proceed, this blog post aims to discuss how React components are created and used, but doesn’t wade into the various ways components may be defined initially. We’ll dedicate our next blog post in the series to the topic of defining React components.

7 Strengths of #ReactJS Every Programmer Should Know About

  • React is blazingly fastIt is actually much faster than manually manipulating the DOM, which is the reason why Flipboard has built their own React-Canvas library to achieve 60fps performance on the mobile web.Modifying the DOM after every change can be slow, therefore React creates a simplified JavaScript version of DOM called VirtualDOM and uses a diffing algorithm to apply only necessary changes to the real DOM.JavaScript is a reasonably fast language, and typical web apps consist of only several hundreds of DOM elements.
  • They have invested years into creating the Facebook site, so a complete rewrite just to use React would not be justifiable.It is really easy to use React with jQuery, Angular, Backbone, or any other JavaScript framework.4.
  • You can create truly native apps with JavaScript and other tools you know from the web.
  • Some of the biggest innovations in React were actually inspired by ClojureScript, some were taken from Ember, and some come from Elm.Whether it is ClojureScript, Elm, Angular, or Ember, these great people are part of our Reactive Community, and they remind us why we should work together every day.The React ecosystem is extremely focused on developer experience and productivity.
  • But Facebook is not the only big supporter of the React community: Yahoo, Mozilla, Airbnb, Netflix, and other big companies use React in production and have supported the community with useful open-source libraries and tools.6.

In the past six years, we have seen a huge rise of JavaScript on the web. It has become a prominent server-side language and a popular compile target for other languages. Offline-first SPAs have…

React Ecosystem Setup — Step-By-Step Walkthrough – codeburst

#ReactJS Ecosystem Setup — Step-By-Step Walkthrough:

  • It’ll recursively go through every dependency and the dependencies’ dependencies, resolving all the way down.It’ll transpile our farm-fresh, cutting-edge ES6+ down to ES5 so that it’ll work on virtually every browser.It’ll minify our code by removing whitespace and shortening variable names, reducing the final file size.In the end, we’ll be able to write modular, modern Javascript and CSS that we can work with easily and use best practices on.Getting StartedLet’s create a folder named src in our root directory.

  • To make webpack minify your code, use the production flag, -p. Type in webpack -p and look at the bundle file.

React Ecosystem Setup — Step-By-Step Walkthrough

  • An issue with using a bundle instead of our source code is that it makes debugging more difficult, because the stack trace now refers to our bundle file.
  • Using the flag during development means webpack will watch our files and re-generate the bundle every time we save a change.
  • This code is telling webpack to test the files in our directory and look for the filenames matching the regex in the property.
  • Now we can use ES6 code and the bundle generated by webpack will contain only ES5 code.
  • We’ll have to add a term to our file to tell it that we’re writing React code.

Understand what React, Webpack, and Babel are doing and how to configure them yourself.

Angular to React: Fullstack Academy Updates its…

We've switched our curriculum to @reactjs!  #JavaScript #webdevelopment #FrontEnd #coding

  • Fullstack Academy has switched from Angular 1.x to React throughout our immersive curriculum.
  • We also are keeping our extensive Angular 1.x curriculum for students who want to see how the applications that we build in React would also work in Angular.
  • We’ve also seen students excited by the ideas in FRP and are looking at integrations with RxJS/BaconJS.
  • The shift applies across all our campuses and programs (including Fullstack Chicago and the Grace Hopper Program ).
  • When we first started Fullstack Academy, we were excited about how we could respond quickly as technology changed and the market moved.

In order to mirror industry demand and improve the relevancy of Fullstack Academy’s curriculum, a major technology switch from Angular.js to React has recently
