## What it is
Darkmode.js is a lightweight vanilla JavaScript library that adds a dark-mode/night-mode toggle to any website using CSS mix-blend-mode. It provides an automatic floating widget, remembers the user's choice in localStorage, and respects the OS prefers-color-scheme setting.

## Use cases
- add dark mode to a website in seconds
- drop-in night mode toggle widget for any site
- respect user's OS dark theme preference
- remember dark mode setting across visits
- programmatically toggle dark mode without a widget
- add dark theme to WordPress or Drupal site

## When to choose
- you want a zero-config, copy-paste dark mode solution
- your site lacks a native dark theme and you need a quick fix
- you want a lightweight vanilla JS widget with no dependencies

## When to avoid
- you need a fully designed, per-component dark theme rather than a blend-mode filter
- mix-blend-mode rendering artifacts are unacceptable for your design
- you need fine-grained theming with CSS variables or design tokens

## Facets
- artifact type: library
- maturity: maintenance
- function: ui-components, theme
- domain: frontend, web-development, accessibility
- platform: browser
- tags: dark-mode, vanilla-js, widget, mix-blend-mode, npm-package, theme-toggle, javascript, nodejs
