React Hooks: The Deep Cuts
13.7.2022
Hooks are reusable functions. They allow you to use state and other features (e.g. lifecycle methods and so on) without writing a class. Hook functions let us “hook into” the React state lifecycle using functional components, allowing us to manipulate …

Theming and Theme Switching with React and styled-components

The Hooks of React Router
12.2.2020
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 you are looking for a quick primer on the new patterns of React Router. But before we look at hooks, we will start off with a new route rendering...
Testing React Hooks With Enzyme and React Testing Library
29.11.2019
As you begin to make use of React hooks in your applications, you’ll want to be certain the code you write is nothing short of solid. There’s nothing like shipping buggy code. One way to be certain your code is bug-free is to write tests. And testing React hooks is not much different from how React...
A Dark Mode Toggle with React and ThemeProvider
25.9.2019
I like when websites have a dark mode option. Dark mode makes web pages easier for me to read and helps my eyes feel more relaxed. Many websites, including YouTube and Twitter, have implemented it already, and we’re starting to see it trickle onto many other sites as well.
In this tutorial, we’re...
Thinking in React Hooks
25.9.2019
Amelia Wattenberger has written this wonderful and interactive piece about React Hooks and details how they can clean up code and remove all those troubling lifecycle events:
React introduced hooks one year ago, and they've been a game-changer for a lot of developers. There are tons of how-to...
Hamburger Menu with a Side of React Hooks and Styled Components
10.9.2019
We all know what a hamburger menu is, right? When the pattern started making its way into web designs, it was both mocked and applauded for its minimalism that allows main menus to be tucked off screen, particularly on mobile where every pixel of space counts.

Using requestAnimationFrame with React Hooks
21.8.2019
Animating with requestAnimationFrame should be easy, but if you haven’t read React’s documentation thoroughly then you will probably run into a few things that might cause you a headache. Here are three gotcha moments I learned the hard way.
TLDR: Pass an empty array as a second parameter...
Run useEffect Only Once
30.7.2019
React has a built-in hook called useEffect. Hooks are used in function components. The Class component comparison to useEffect are the methods componentDidMount, componentDidUpdate, and componentWillUnmount.
useEffect will run when the component renders, which might be more times than you think....
Build a Chat App Using React Hooks in 100 Lines of Code
15.7.2019
We’ve looked at React Hooks before, around here at CSS-Tricks. I have an article that introduces them as well that illustrates how to use them to create components through functions. Both articles are good high-level overviews about the way they work, but they open up a lot of possibilities...
Getting to Know the useReducer React Hook
26.6.2019
useReducer is one of a handful of React hooks that shipped in React 16.7.0. It accepts a reducer function with the application initial state, returns the current application state, then dispatches a function.
Here is an example of how it is used;
const [state, dispatch] = useReducer(reducer...

Managing State in React using Unstated-Next
17.6.2019
In a previous post, we saw how to manage state using Unstated. As you might recall, Unstated uses React’s built-in setState to allow you create components that can consume state by subscribing to a provider — like the React’s Context API.
Well, we’re going to build off that last post by looking...
Intro to React Hooks
18.1.2019
Hooks make it possible to organize logic in components, making them tiny and reusable without writing a class. In a sense, they’re React’s way of leaning into functions because, before them, we’d have to write them in a component and, while components have proven to be powerful and functional...
