Why ReactJS Is More in Demand

One of the most in demand technologies right now is #ReactJS



#WebDev #javascript  #WebApp

  • As stated already, the most compelling feature of React is that it reduces the complexities of user interface.
  • If the mechanism that we are trying to interface can comprehend Javascript, we can use React to build the user interface for it.
  • You describe the user interfaces in React languages and tell it what you want, it will take care to translate your description and prepare the actual interface.
  • You will illustrate user interfaces to React with simple components.
  • When state of a component changes, its User Interface will change automatically.

ReactJS is a JavaScript library for building user interfaces. According to Google Trends data last 5 years in increased popularity of ReactJS development and we explain why ReactJS is more in demand.

Styling React for Reuse

  • We’ve all excitedly installed a third-party component that beautifully fit our functional needs, only to sacrifice design, and waste hours covering our code in !
  • Between state-based components, class naming conventions, and the inline versus stylesheet wars, it’s difficult to wrap your head around your own components, let alone releasing them for reuse.
  • In this session, we’ll take all that information and distill it into an easy to digest discussion for those who are looking to standardize their own components, or release their first components for public use.
  • My goal is to help the community, at large, think about CSS in their OSS components in an extensible way.

In this session, we’ll take all that information and distill it into an easy to digest discussion for those who are looking to standardize their own components, or release their first components for public use.

  • Add responsive behaviour exactly where you want it, with the flexibility to create fixed non-responsive layouts or layout sections.
  • WebUI includes a flexbox module as well as a traditional grid system by default, as it is recommended to make use of both to provide maximum flexibility and browser support.
  • WebUI uses a 20 column grid system to create grid layouts.
  • Here is a quick example of a shared layout structure with a container and some rows and columns: – – The respond-bp-3-under class on the columns will cause the form to re-render for a mobile screen size at the medium breakpoint.
  • Responsive gutters can be used with any container type or on any row type, but should not be used directly on columns, so there is no problem with placing containers inside columns and applying responsive gutters to the containers.

GitHub is where people build software. More than 27 million people use GitHub to discover, fork, and contribute to over 80 million projects.

Installation Steps or Guides for ReactJS

  • After the folder is created, we need to open it and create empty package.json file inside by running npm init from the command prompt and follow the instructions.
  • Create the index.html file inside the root folder, this is just regular HTML.
  • We are setting div id = “app” as a root element for our app and adding main.js script, which is our bundled app file.
  • We need to import this component in main.js and render it to our root App element, so we can see it in the browser.
  • If you want to make the component usable in other parts of the app, you need to export it after creation and import it in the file where you want to use it.

react installation in windows : Today, we will see how to install an environment and require dependencies for development of reactjs application. The environment and configuration files installation process is bit time taking but not that complex. First thing First, we need NodeJS, so if you don’t have it installed, check the below official website link for NodeJS Installation :

6 Pro Tips from React Developers

6 Pro Tips from React Developers

☞ 

#Reactjs #Developers

  • If you’re new to React, you could benefit from learning from the success—and failures—of React developers who’ve learned valuable lessons about the framework.
  • If you don’t need internal state or lifecycle methods on your component, use a functional component instead.
  • A functional component is a pure JavaScript function that accept as its argument and returns a React element.
  • But if you are using an ES6 class, you’ll need to bind manually since React doesn’t autobind the functions inside that component.
  • With React Developer Tools, available as a Google Chrome and Firefox extension, as well as a standalone app for other environments, you can quickly view your component hierarchy, inspect and edit a component’s props and state, and invoke methods on a component within the DevTools.

Top React and Redux Packages for Faster Development

Top React and Redux Packages for Faster Development

#Reactjs #Redux

  • After all, we always want our development tools to – Via GiphyIf you are a beginner in React, you may find some of the packages helpful in debugging or visualising various abstract parts of your app.
  • React StorybookWhile creating applications in React, you must have had this thought at least once: What if I could see a rendition of the component that I am using(or making) and see how it behaves under different combinations of props, states, and actions.
  • Demo from storybook’s repoSome highlights are — – Storybook runs outside of your app.This allows the components to be developed in isolation from the app development.It also means that you do not have to worry about various dependencies while creating the components.Other similar packages are: React Cosmos, React Styleguidist -…
  • It keeps track of the props and states, and when a component is re-rendered without any change in the props or the state, the package logs the details in the console.
  • Image from Why did you update’s repoCreate React App(CRA)Not exactly a development tool, but over the years I have found that this package is really helpful in creating rapid prototypes.

React has grown in popularity over the last few years. With that, a lot of tools have emerged that make developer’s life easy and development fun. They are going to help us in achieving the extra…

Migrating to React’s New Context API – kentcdodds

📝 Article => Migrating to React’s New Context API by @kentcdodds  | #ReactJS

  • Because of this significant change, I’m making an update to my advanced component patterns course on Egghead.io to use the new API rather than the old one.
  • The Old Context APIHere’s the version of the implementation with the old context API: – const TOGGLE_CONTEXT = ‘__toggle__’ – function ToggleOn({children}, context) { – const {on} = context[TOGGLE_CONTEXT] – return on ?
  • null : = { – [TOGGLE_CONTEXT]: ToggleButton(props, context) { – const {on, toggle} = context[TOGGLE_CONTEXT] – return ( – Switch on={on} onClick={toggle} {…props} / – ) – } – ToggleButton.contextTypes = { – [TOGGLE_CONTEXT]: Toggle extends React.Component { – static On = ToggleOn – static Off = ToggleOff – static…
  • on}), – () = ) – getChildContext() { – return { – [TOGGLE_CONTEXT]: { – on: this.state.on, – toggle: this.toggle, – }, – } – } – render() { – return div{this.props.children}/div – } – }With the old API, you had to specify a string for what context your component…
  • Here’s my new version of this same exercise: – const ToggleContext = React.createContext({ – on: false, – toggle: () = {}, – })class Toggle extends React.Component { – static On = ({children}) = ( – ToggleContext.Consumer – {({on}) = (on ?

With the recent release of React 16.3.0 came an official context API. You can learn more about the why and how behind this API from my previous blog post: “React’s ⚛️ new Context API”. Because of…

Understanding React `setState`

  • The object contains the part of the state we want to update which, in this case, is the value of .
  • The reconciliation process is the way React updates the DOM, by making changes to the component based on the change in state.
  • When the request to is triggered, React creates a new tree containing the reactive elements in the component (along with the updated state).
  • This tree is used to figure out how the component’s should change in response to the state change by comparing it with the elements of the previous tree.
  • When building React applications, there are times when you’ll want to calculate state based the component’s previous state.

React components can, and often do, have state. State can be anything, but think of things like whether a user is logged in or not and displaying the correct username based on which account is active. Or an array of blog posts. Or if a modal is open or not and which tab within it is active. React components with
