Hey, React Native! I’d find out why barcode implementation isn’t stable. But for now, let me try Flutter. Let’s see how it goes. Sometime last year, I read a few materials on Flutter, but due to the fact that I had no project to work with, I wasn’t consistent with it. This is a chance to dive deeper into Flutter. React.Component render componentDidMount props/state dangerouslySetInnerHTML React is a JavaScript library for building user interfaces. This guide targets React v15 to v16. I've put together for you an entire visual cheatsheet of all of the concepts and skills you need to master React in 2020. But don't let the label 'cheatsheet' fool you. This is more than a mere summary of React's features. My aim here was to clearly and concisely put.

Or to use on the desktop, install FontAwesome.otf, set it as the font in your application, and copy and paste the icons (not the unicode) directly from this page into your designs.
Ever since I started using TypeScript, I can't stop using it. Sometimes finding the correct type and where you should import it from can be a real headache. Especially when building a ReactJS application. This blog post is a great chance to publicly document my most used React TypeScript types. I focus on functional components and react hooks.
The structure of the article is that each paragraph is a standalone tip.
To create a React TypeScript project, we can use Create React App:
There have been lots of talks about the right way to import React. This is the most updated way to do it:
The return type of a functional component is ReactElement
If you want to extend the props of a native HTML element, you can use the generic class HTMLAttributes. Let's say I want to create a new button:
Note that we use destructuring to forward the props to the button element.
The children prop is of type ReactNode.
React's events system uses its own types and not the native HTML events. Make sure to import the event from the react library. import { MouseEvent } from 'react'.
Pass the correct type to the useRef generic. If you want to create a ref to an input element:
The ref.current type will automatically be HTMLInputElement.
The same goes for useState.
If you provide an initial value in both cases, the type will be inferred implicitly.

When creating custom hooks make sure to explicitly set the returns type. Otherwise, TypeScript may infer incorrectly the types.
