The Future of State in React

The Future of #State in #reactjs   #javascript #developers

  • React’s new Context API will be the go-to solution for sharing state simply™️.
  • In this post, I’ll describe Context by creating a simple theme-switching component: – – Since Context won’t be live until React 16.3, I’ll be using the polyfill.
  • Creating a Context instance is as simple as calling a function with a default value .
  • Context’s has less emphasis on global state than Redux and can be used to as little or as large a scale that you’d want: just like MobX.
  • In the following snippet, I set up a React Component that manages the state that our Provider will pass to those willing to consume it: – – Consumers must be descendants of its context’s Provider for it to access the value it wants.

The days of relying on state-management libraries for non-local state are coming to a close. You wont need Redux anymore. Not even MobX. React’s new Context API will be the go-to solution for sharing state simply™️.

Vue.js vs. React.js: Comparing Two JavaScript UI Component Libraries

  • At a time where large MVC (model-view-controller) frameworks were cutting edge, two-way data binding was considered a feature, and SSR was mostly used for static webpages, React reversed the trend, focusing on building applications from encapsulated view components, one-way data binding, and using SSR on dynamic web pages via the…
  • Dependency tracking gives Vue’s virtual DOM a slight edge over React out of the box, because it can selectively re-render the child components that are actually affected by a change in state by default — no additional coding required.
  • In React, JSX breaks with the convention of keeping JavaScript and HTML separate, by providing a declarative XML-like syntax that allows you to create self-contained UI components that encapsulate all the instructions required to render them within the view: – – The React code above will render into a simple…
  • Under the React umbrella, we have Flux, the application architecture pattern Facebook developed as a state management solution to avoid issues like the infamous phantom unseen message bug, and Redux, a framework agnostic library for providing a simplified implementation of the Flux pattern, which replaces MVC (model-view-controller).
  • Both Vue and React are cutting edge UI component libraries that make use of a virtual DOM, embrace the components based future of web development, support SSR, and Universal JavaScript.

In this article, we’ll explore some of the key differences between the React.js and Vue.js JavaScript libraries, and learn which might be the best fit for your next web project.

React State vs Props explained – codeburst

  • Let me define a React component a plain javascript function side by side.class DummyComponent extends React.Component { render () { return divHey/div }}const DummyFunction = () = console.log(‘Hey’)We defined a React component named DummyComponent and returned a div containing text Hey similarly, we defined a function named DummyFunction and output…
  • Let’s take a look at State.React Component StateA state in React Component is its own local state, the state cannot be accessed and modified outside the component and can only be used inside the component which is very similar to, you already guessed it a function own local scope.
  • Let’s demonstrate this with an example.class DummyComponent extends React.Component { state = { name: ‘Manoj’ } render() { return divHello {this.state.name}/div; } }const DummyFunction = () = { let name = ‘Manoj’; console.log(`Hey ${name}`)}As you can see a component state can be compared to a function local scope.
  • Let’s take a look how we can use props in react.class DummyComponent extends React.Component { render() { return divHello {this.props.name}/div; } }// when using the componentDummyComponent name=”Manoj” /DummyComponent name=”Ajay” /We used one react component in multiple places here but with a different name.
  • Props, on the other hand,make components reusable by giving components the ability to receive data from the parent component in the form of props.We also get to know that React components are pretty similar to normal JS functions so from the next time keep this thing in mind 😉 .

Before jumping to state vs props we have to compare a React component with a javascript plain function. Let me define a React component & a plain javascript function side by side. We defined a React…

The Pros and Cons of ReactJS for your Online Business

The Pros and Cons of ReactJS for your #OnlineBusiness via @janlgordon

  • With React, it is possible for webmasters and online business owners to develop large web-based applications that change data while reloading pages.
  • Webmasters can also use React together with other forms of frameworks or JavaScript libraries like Angular in MVC.
  • It makes it possible to reuse components that didn’t produce changes, and this makes programming more comfortable and precise for online business owners.
  • The great news for webmasters is that Google might still find the React component when just the client-side is rendered.
  • ReactJS is a great framework for online business.

This isn’t quite a ReactJS guide for the layman. But it is a useful for business owners, if only to glean enough to know how to talk with your techie

Tutorial on how to make a custom React renderer #ReactJS

Tutorial on how to make a custom React renderer  #ReactJS

  • This is a small tutorial on how to build your custom React renderer and render the components to the host environment you need.
  • In part three, we will build a function that will parse the input component and will return the output (rendered children and props).
  • In part four, we will create a render method which will render our input component.
  • We will create a custom renderer that will render a React component to a word document.
  • It generates a output stream and not a file.

How to learn React Native

  • React Native is the hot topic these days for building mobile apps.
  • Learning ES6 makes it much easier to write React and React Native code.
  • The main things you should have learnt after completing the tutorial are Lifecycle of a React Component and what are props and state – – React Native uses Flexbox layout style to render views in a much easier and responsive way.
  • Since an important function in mobile app is how to navigate between screens, it is important to know how it’s done in React Native.
  • As of this writing, RN recommends to use libraries like ReactNavigation and React Native Navigation to use same code for both Android and iOS.

Here is a small guide for Android/iOS developers on how to learn React Native.
