A custom React Hook to help you implement a dark mode component


A custom React Hook to help you implement a “dark mode” component for your application.

useDarkMode works in one of two ways:

  1. By toggling a CSS class on whatever element you specify (defaults to document.body).
    You then setup your CSS to display different views based on the presence of the selector. For example, the following CSS is used in the demo app to ease the background color in/out of dark mode.

    body {
      background-color: #fff;
      color: #333;
      transition: background-color 0.3s ease;
    body.dark-mode {
      background-color: #1a1919;
      color: #999;
  2. If you don’t use global classes, you can specify an onChange handler and take care of the implementation of switching to dark mode yourself.

Requirement ⚠️

To use use-dark-mode, you must use . React Hooks is currently at
RFC stage.


$ npm i use-dark-mode


const darkMode = useDarkMode(initialState, optionalConfigObject);


You pass useDarkMode an initialState (a boolean specifying whether it should be in dark mode
by default) and an optional configuration object. The configuration object contains the following.

Key Description
className The class to apply. Default = dark-mode.
element The element to apply the class name. Default = document.body.
onChange A function that will be called when the dark mode value changes and it is safe to access the DOM (i.e. it is called from within a useEffect). If you specify onChange then className and element are ignored (i.e. no classes are automatically placed on the DOM). You have full control!

Return object

A darkMode object is returned with the following properties.

Key Description
value A boolean containing the current state of dark mode.
enable() A function that allows you to set dark mode to true.
disable() A function that allows you to set dark mode to false.
toggle() A function that allows you to toggle dark mode.


Here is a simple component that uses useDarkMode to provide a dark mode toggle control.
If dark mode is selected, the CSS class dark-mode is applied to document.body and is removed
when de-selected.

import React from 'react';

import Toggle from './Toggle';
import useDarkMode from 'use-dark-mode';

const DarkModeToggle = () => {
  const darkMode = useDarkMode(false);

  return (
      <button type="button" onClick={darkMode.disable}>
      <Toggle checked={darkMode.value} onChange={darkMode.toggle} />
      <button type="button" onClick={darkMode.enable}>

export default DarkModeToggle;

How native is React Native? | React Native vs Native App Development

If you are undertaking a mobile app development for your start-up or enterprise, you are likely wondering whether to use React Native. As a popular development framework, React Native helps you to develop near-native mobile apps. However, you are probably also wondering how close you can get to a native app by using React Native. How native is React Native?

In the article, we discuss the similarities between native mobile development and development using React Native. We also touch upon where they differ and how to bridge the gaps. Read on.

A brief introduction to React Native

Let’s briefly set the context first. We will briefly touch upon what React Native is and how it differs from earlier hybrid frameworks.

React Native is a popular JavaScript framework that Facebook has created. You can use this open-source framework to code natively rendering Android and iOS mobile apps. You can use it to develop web apps too.

Facebook has developed React Native based on React, its JavaScript library. The first release of React Native came in March 2015. At the time of writing this article, the latest stable release of React Native is 0.62.0, and it was released in March 2020.

Although relatively new, React Native has acquired a high degree of popularity. The “Stack Overflow Developer Survey 2019” report identifies it as the 8th most loved framework. Facebook, Walmart, and Bloomberg are some of the top companies that use React Native.

The popularity of React Native comes from its advantages. Some of its advantages are as follows:

  • Performance: It delivers optimal performance.
  • Cross-platform development: You can develop both Android and iOS apps with it. The reuse of code expedites development and reduces costs.
  • UI design: React Native enables you to design simple and responsive UI for your mobile app.
  • 3rd party plugins: This framework supports 3rd party plugins.
  • Developer community: A vibrant community of developers support React Native.

Why React Native is fundamentally different from earlier hybrid frameworks

Are you wondering whether React Native is just another of those hybrid frameworks like Ionic or Cordova? It’s not! React Native is fundamentally different from these earlier hybrid frameworks.

React Native is very close to native. Consider the following aspects as described on the React Native website:

  • Access to many native platforms features: The primitives of React Native render to native platform UI. This means that your React Native app will use many native platform APIs as native apps would do.
  • Near-native user experience: React Native provides several native components, and these are platform agnostic.
  • The ease of accessing native APIs: React Native uses a declarative UI paradigm. This enables React Native to interact easily with native platform APIs since React Native wraps existing native code.

Due to these factors, React Native offers many more advantages compared to those earlier hybrid frameworks. We now review them.

Implementing a dark theme toggle with react-redux and styled-components

To keep things simple and concise, we’ll start fresh with npx create-react-app dark-toggle . While we’re in our command line, let’s get the npm packages out of the way as well:
npm install styled-components styled-theming redux react-redux
styled-components: we’ll use this library to create isolated components that encapsulate their own styling
styled-theming: this library offers a very clean API to work with multiple themes in your styled components
redux and react-redux will do the heavy lifting regarding state management

Class-less Components in React

While coding this week, I had to convert one of my class components in React to a functional component.

Why would I need to do that? After all, the parent component sees the two types of components as identical. Sure, functional components can be shorter, require less boilerplate, and maybe even perform better. But that’s not why I needed to do it. I was using an npm package that had React hooks and hooks are for functional components only. React Hooks, added in React 16.8, allow functional components to manage state and replace lifecycle methods. To use the hook I needed I had to convert my class components to a functional.

Here are the steps I followed to change my class component to a functional component:
