Jennifer Williams shows us how use Redux with Hooks When I was first learning Redux I found all the moving parts and files incredibly hard to wrap my head around. Surprisingly, React hooks made the process of using Redux a lot easier for me. The post provides us with a two-fold example. One “without hooks” …
To work with forms in React two approaches are to either use Controlled Components or use Uncontrolled Components (as detailed here). Swyx shares a third way of working with forms: A lower friction way to handle form inputs is to use HTML name attributes. As a bonus, your code often turns out less React specific! …

Nice post comparing these three approaches and detailing why you should use the version with hooks. // #1 – Hooks const MyComponent = () => { const mousePosition = useMouse(); // mousePosition.x, mousePosition.y } // #2 – Render Props const MyComponent = () => { return ( <Mouse> {({ x, y }) => { // …

useDeepCompareEffect Hook: A useEffect using deep comparison
A custom Hook by Kent C. Dodds (who else?) that might come in handy for “those situations”: React’s built-in useEffect hook has a second argument called the “dependencies array” and it allows you to optimize when React will call your effect callback. React will do a comparison between each of the values (via Object.is) to …

Chris Coyier wants to create a Card Component in React. But then he suddenly finds himself down the rabbit hole: how flexible does he make it? What is configurable and what is not? Where to draw the line? It sounds very familiar, as I’m always pondering over things like this when writing libraries/reusable things in …

A common misconception about React is that you need to set up an entire toolchain to get started with it. While that might have been true in the past, that certainly isn’t the case today. From the React Docs: The majority of websites aren’t, and don’t need to be, single-page apps. With a few lines …

React Query provides you with a set of hooks to fetch data in React. Think of pages that use pagination, infinite scroll, auto-refetching, etc. It’s backend agnostic, so sources can be REST, GraphQL, etc. Here’s an example that uses pagination import React from 'react' import fetch from '../libs/fetch' import { usePaginatedQuery } from 'react-query' export …

Good post by Lachlan Young with a simple use case for using createRef (Class Components) and useRef (Function Components): focusing an external component (here: TextField from Material UI) when your own parent component mounts. I especially like the final thoughts at the end of the post: If you had no need for a ref besides …

If you’re looking to get started with React Router – or looking to migrate away from version 4 – this article on CSS-Tricks will introduce to it and its hooks: React Router 5 embraces the power of hooks and has introduced four different hooks to help with routing. You will find this article useful if …
useEffect(fn, []) is not the new componentDidMount() Brad Westfall from React Training on why the React hook useEffect(fn, []) is not the same as componentDidMount(): When developers start learning hooks having come from classes, they tend to think “I need to run some code once when we mount, like how componentDidMount() works. Ah, I see that useEffect with an empty dependency array …
