## What it is
Sugar High is a super lightweight, zero-dependency syntax highlighter library that tokenizes source code into styled spans with a tiny custom parser. It ships with 25 built-in languages (JavaScript/JSX and TypeScript by default), light/dark token palettes driven by CSS variables, and integrates with React and remark-based Markdown pipelines.

## Use cases
- add syntax highlighting to code blocks in my react blog
- lightweight alternative to prism or shiki for code highlighting
- highlight code snippets in markdown docs via a remark plugin
- display jsx and typescript snippets with colors on my site
- zero-dependency syntax highlighter that keeps bundle size small
- theme code block token colors with css variables for light and dark mode
- highlight code in a static site without shipping heavy grammar files

## When to choose
- you need minimal bundle size and zero runtime dependencies
- you want full CSS control over token colors via custom properties and per-line styling
- you render JavaScript, JSX, TypeScript, or any of its 25 built-in languages in React or remark/MDX sites
- you prefer a tiny tokenizer over heavyweight grammar engines

## When to avoid
- you need exhaustive or highly accurate grammar coverage for complex or obscure languages
- you want a batteries-included ecosystem with many official plugins, line-number widgets, or UI chrome
- you require IDE-grade highlighting fidelity for deeply nested or templated code
