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.

Includes() vs indexOf() in JavaScript

  • ES2016 Specifications included the  method  for  Array data structure.
  • But in ES5 we are used to performing operations like this with method.
  • Let’s perform the same operation with method.
  • Let’s see how method will handle this operation.
  • The method  does not distinguish between -0 and +0 – – Typed Arrays will also have a method

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…

  • 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

Caching images in React Native – React Native Training – Medium

  • The example app using images from Unsplash.This is the result of opening and closing the app five times.
  • The app downloads the images every time it launches, which is very much undesired and poor design.
  • Not only does this result in exponential data usage, which is an unpleasant surprise for your customers, it also makes your apps reliant on network connection every time external images are shown.
  • To provide our apps with minimal data usage, faster reponse time and improved offline capabilities, let us take a look at how we can cache external images.
  • import { CachedImage } from ‘react-native-cached-image’;In my example app, I set up a FlatList to show the images.

I can still recall the moment where I realised something was terribly wrong.
I was on the verge of publishing my first app. I had gone over everything and I felt I had my bases covered. It was then…
