nottheme v1.0.3

nottheme

Accessible theme switcher for Astro.

Installation

npm i nottheme

Usage

See the demo.

If you need to know when the theme changes, set window.__nottheme_onChange to a function:

window.__nottheme_onChange = (key: string, value: string) => {
  console.log(key, value);
};

Features

• Static sites (localStorage)
• Zero JavaScript (:has())
• Zero JavaScript with SSR (cookies)

How it works

There are three components:

• a component that generates a CSS file based on your specified configuration
• a JavaScript script which saves preferences if JavaScript is enabled
• a component to change the theme on your site

With JavaScript enabled:

• Classes are applied to the body element on page load
• Settings are saved to localStorage
• Changes are made through event listeners

With JavaScript disabled:

• Classes are applied to the nottheme class using :has()
• Settings are not saved and will reset on page navigation or refresh
• Changes are made through CSS selectors (selection component must be on every page!)
