## What it is
next-themes is a small React library providing theme management for Next.js apps, supporting system preference, custom themes, and flash-free dark mode. It abstracts theme switching with SSR-safe handling in just a couple lines of code.

## Use cases
- add dark mode to a Next.js app
- respect user system color scheme preference
- avoid theme flash on page load
- support multiple custom color themes
- toggle themes with a React hook
- persist theme choice across visits

## When to choose
- you need dark mode in Next.js with no flash of wrong theme
- you want SSR-safe theme switching with minimal setup
- you need system preference detection plus manual override

## When to avoid
- you are not using React or Next.js
- you need complex multi-tenant theming or design token systems
- you use a CSS-in-JS solution with its own theming

## Facets
- artifact type: library
- maturity: stable
- function: theme, state-management, ui-components
- domain: web-development, frontend
- platform: browser
- tags: nextjs, dark-mode, react, theming, system-preference, nodejs, web-server
