@petegi/pi-color-scheme-switcher v0.1.1
PiColorSchemeSwitcher
Simple color scheme switcher for your site.
When connected to the DOM, checks if LocalStorage has the value with current scheme (by given key, look at the available attributes).
If no value is found in the LocalStorage, checks the media prefers-color-scheme.
Default styling is just button with specified min-width and height. To style the button on your own, look at the Parts and slots section to see how the element is structured.
By default, if you place the code in your HTML, the start of your document will look like:
<html color-scheme="dark"></html>`Requirements
Node v16+ if you'd like to build the component.
CustomElement doesn't have any dependencies other than vite used to build things up (devDep only).

Special attributes
CustomElements spec doesn't give the ability to specify custom pseudoclasses, so these attributes show what current scheme is.
They should not be used in any other way than in CSS to style the element.

| dark | Current color scheme is dark |

| additionalHeaders | Object | {} | Additional headers to be sent with each request |
To use these properties, grab the element (e.g. using querySelector) and do it like:
const switcher = document.querySelector('.color-switcher');
switcher.additionalHeaders = { /* your custom headers */ }Parts and slots
Custom Element parts are useful for styling the components's inner elements. Slots on the other hand, are used to place your content inside them.
PiColorSchemeSwitcher allows you to style all of the elements on your own. Below you can see how the component is built, with all of it's parts and slots.
