  • 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.

Writing Easily Testable Code with Stateless Components in React.js

Writing Easily Testable Code with Stateless Components in #React.JS  #javascript #testing

  • By relying on pure components, developers end up writing reusable code that’s extremely easy to test, which leads to better application architecture.
  • Personally, I like the term “pure component” because it’s indicative of what the code really is — a pure function sprinkled with some JSX.
  • In addition to these benefits, pure components also make it extremely easy to test code with any crazy props that you wish.
  • Like a pure function, pure components will always map the same input to the same output, therefore, if we can think of the scenario, we can test how our component will react.
  • As we just saw, the code for functional components provides us awesome intel for everything we need to know in order to write effective tests.

Functional Stateless Components provides clean syntax that allows us to
write more declarative code. We will look at stateless components and finish up with some unit tests in this article.

Styling in React – codeburst

  • A style rule will have been inlined ğŸ‘� – Before digging into third party CSS in JS, let’s roll back to creating it ourself to understand the core benefits.
  • ğŸ‘� – A major benefit of defining CSS in JS is to be able to conditionally generate styles.
  • You’re also inlining everything 😭 – Third party packages exampleLuckily, there are some great third party packages to aid with handling CSS in JS 😌 – I don’t have experience with them all so I will be using styled-components for these examples.
  • If you’d rather take a quick look at styled-components before going any further, check it out here ğŸ‘� Don’t worry though, I will keep any examples intuitive and simple.
  • But consider that our CSS will have to contain styling for when the nav is open and closed ğŸ‘� – Using styled-components we could create something more along the lines of – That is so much clearer ğŸ˜� Any styling declaration via classNames are extracted and we are left with…

Styling is a huge part of the user experience for your apps. You’ve got a new design and you’re going to build your new awesome app in React. But how do you go about implementing that design? It…

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.

10 key differences between ReactJS and React-Native? – Georgia Hovis

10 key differences between #ReactJS and #React-#Native?


#reactjs #reactnative

  • ReactJS and React Native are some emerging technology for web and mobile development.
  • React-Native and React-JS are quite similar, yet it has many differences which one should know before starting developing apps using this platform.
  • Here, are some important differences which should know by every ReactJS web developer should learn before using this technology for the offshore web development purpose.
  • Moreover, the community around React-Native gets very big and keeps growing, the technology is not going away anytime soon, and I would recommend any web developer who wants to develop a mobile app.
  • Thus, it hardly surprises that both react js and react native enjoy so much popularity and many offshore development firms prefer it for developing all type of web application for their business.

ReactJS and React Native are some emerging technology for web and mobile development. This project was started with the goal of simplifying the development process and provide the more comfortable user experience. This library allows for building a web interface with JavaScript. React-Native and React-JS are quite similar, yet it has many differences which one…

6 Pro Tips from React Developers — SitePoint

We've got 1 #reactjs tip from a pro devs for you. Watch  for all 6 tips.

  • Tip 1: Use functional components – Cam Jackson – 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 props as its argument and returns a React element.
  • Benefits of functional components: – – Less code – Easier to understand – The component is stateless, so you avoid accidentally storing state on a component you shouldn’t – The component is simpler to test – There’s no this binding – It’s easier to see where and when to extract…
  • Keep Tip 1 in mind and extract blocks of code into functional components whenever possible.
  • Tip 6: Use React Developer tools – Brian Gates – 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…

Writing Easily Testable Code with Stateless Components in React.js

Writing Easily Testable Code with Stateless Components in #React.JS  #javascript #testing

  • The use of Stateless Functional Components (a.k.a. “pure” or “dumb” components) in React.js continues to grow since first it was released in React 0.14, and for good reasons.
  • By relying on pure components, developers end up writing reusable code that’s extremely easy to test, which leads to better application architecture.
  • Personally, I like the term “pure component” because it’s indicative of what the code really is — a pure function sprinkled with some JSX.
