A simple dark mode toggle
Add dark mode styling to your app/website with a simple toggle button. The selection is saved in localStorage.
Install
npm install @luukone/darkmode-toggle
Usage
Create an element where you want to inject the toggle button in:
<div id="screen-mode">
// the toggle button will be injected here
</div>
Create a .dark-mode class in your css file:
.dark-mode {
background: #000;
}
.dark-mode h1 {
color: #CCC;
}
Import the package in your javascript file and create an instance with the following arguments:
- the element you want to inject the toggle button in
- the name of the css class where your dark mode styles will live
Example:
import Dark from '@luukone/darkmode-toggle';
new Dark(document.querySelector('#screen-mode'), 'dark-mode')
Add the following script right after the <body> tag:
<body>
<script>
if (localStorage.getItem('screen_mode')) {
document.querySelector('body').classList.add('dark-mode')
}
</script>
// content
This way the browser will render the dark mode styles before rendering any other styles.
[optional] get a nice looking toggle button by importing the following css file or by directly copying the css code from w3schools.
@import '~@luukone/darkmode-toggle/dark-mode';
