Making of a component library for React – Hacker Noon

Making of a component library for React  #reactjs

  • For this library, this is what I had at the end: – assets/ — Skip this folder, this is just for images I had in API docsbuild/ — UMD and ES module build files + sourcemaps.examples/ — This folder contains test .
  • PopupMenu header partAs we build components for UI we include style files, rollup allows us to make bundles with styles and images the same way as webpack does.
  • import React, {Component} from ‘react’;In my case I even need to use React to provide context to child components this old way: (old because recently React introduced new Context API).
  • I have PopupTable that takes popupWidth of the parent PopupMenu – React context in PopupMenu classI would like to also highlight classnames npm module that does pretty good job in combining multiple classes from CSS modules: – classnames module exampleUsage: – Unit testingFirst you need to decide which unit-testing framework you…

React Tutorial: A Comprehensive Guide to learning React.js in 2018

  • These components are defined either in pure JavaScript or they can be defined in what the React team calls “JSX”.
  • The reason the React team went with this approach is because, since the virtual DOM is a JavaScript representation of the actual DOM, React can keep track of the difference between the current virtual DOM(computed after some data changes), with the previous virtual DOM (computed befores some data changes).
  • In more layman’s terms, because manipulating the actual DOM is slow, React is able to minimize manipulations to the actual DOM by keeping track of a virtual DOM and only updating the real DOM when necessary and with only the necessary changes.
  • The process looks something like this, – – Some user event which changes the state of your app → Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.
  • Signal to notify our app some data has changed→ Re-render virtual DOM -> Diff previous virtual DOM with new virtual DOM -> Only update real DOM with necessary changes.

9 React Tools To Master Your Component Workflow – Bits and Pieces

  • Basically, this project lets you define styled-components that posses their own encapsulated styles so that styling becomes an actual part of your components while avoiding the use of CSS classes as a mediator layer.
  • This project is growing in popularity to become the go-to choice for styling React components, and is defiantly worth checking out for your next app.
  • This project “scans” your app for React components and lets you render components with different states and props while mocking external dependencies, so you can see your app’s state in real-time.
  • React Sketch.appFor the UI designer / dev among you, React-sketchapp is Airbnb’s open source project built for design system which enables the rendering of React components using Sketch.
  • From sharing components between apps with Bit to styling with styled-components or using storybook to render and play with components in isolation, and all the way to less familiar projects like UiZoo and others, the React ecosystem is growing rapidly to help you build an amazing UI.

Best 9 React component tools and libraries that can make all the difference for mastering your work with React components for developing a beautiful UI for your React application. Check out the list.

3 Ways to Fine-tune Presentational Components

Three ways to fine-tune your React presentational components  #reactjs #javascript

  • Here are three ways I’ve found to make React presentational components work as re-usable building blocks.
  • Here are two stories for a text input component: the first shows the component in its valid state, and the second show the component in its invalid state.
  • Instead, extract a new component and pull it up: – – Let the container decide explicitly when and where show presentational components.
  • As you keep pulling presentational components up, they start looking like enhanced native elements, so you’d like to be able to pass all props you would pass to a native element, like or .
  • Inside the component, extract the props you’ve defined yourself and pass the rest to the element that you’re wrapping: – – Here, we’re separating the prop from the rest, and passing the remaining props to the element.

Step by step guide for writing awesome React components

  • Now imagine the most verbose way to write it.class SlothImage extends React.Component { render() { return img src=’sloth.gif’ alt=’Pretty face’ }}export default SlothImageThis code is completely correct and performant but can it be shorter?
  • This component has no use of lifecycle methods.const SlothImage = props = { return img src=’sloth.gif’ alt=’Pretty face’}export default SlothImageTwo lines have been spared by converting the class component to the functional component.
  • /*The props should now be built like this:{ src: ‘sloth.gif’, alt: ‘Pretty face’,}*/export default props = img {…props}The dots are called a spread operator (❧).
  • My personal taste for writing more complex components is as follows:export default ({ separateNext: underline, rightComponent, onRightComponentClick, …rest: imgProps}) = { return ( Row underline SlothImage {…imgProps} / /Row )}If I could pick one rule in writing React components it would be exceeding the 80 characters mark (❧) in a…
  • The sign of overcomplication is the usage of “enum” like props or having too many props.TextInput required width=’col-6′ height=’xlarge’ bgColor=’#a4a4a4′ type=’primary’ suffix=’dollar’ 1337/TextInputEvery component should have a single responsibility (❧) and a reasonable amount of flexibility.

Going through the process of learning and using React and Redux I came to a following conclusion – they are not hard to grasp but are fairly difficult to master. Both are pretty minimal when it comes…

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.
