How we engineered a better Next.js theme library
The article discusses the engineering of a new Next.js theme library. It compares three existing libraries, highlighting their bugs and architectural choices. The author emphasizes the importance of correctly applying themes to avoid user-visible issues during page loads.
- ▪There are three main theme libraries for Next.js and React as of 2026: next-themes, @wrksz/themes, and @teispace/next-themes.
- ▪Each library has significant bugs that can affect user experience without crashing the application.
- ▪The inline script responsible for applying the theme is crucial, as it must execute before any content is rendered to prevent visual glitches.
