## What it is
TypeStyle is a small CSS-in-JS library that lets you write type-safe CSS as TypeScript objects, generating class names without any build tooling or AST transforms. It works with any frontend framework and supports pseudo classes, animations, media queries, and server-side rendering.

## Use cases
- write type-safe css in typescript
- css in js without webpack config
- generate css class names from style objects
- use styles with react or angular
- server side rendered styled components

## When to choose
- you want a tiny, zero-config CSS-in-JS solution with strong TypeScript autocomplete
- your project avoids custom build transforms or module loaders
- you need framework-agnostic styling

## When to avoid
- you prefer modern CSS-in-JS alternatives with larger ecosystems like Emotion or styled-components
- you want plain CSS files or CSS modules
- you need a library under active development - releases have slowed

## Facets
- artifact type: library
- maturity: maintenance
- function: css-framework, ui-components, ssr
- domain: frontend, web-development
- platform: browser, cross-platform
- tags: css-in-js, typescript, type-safety, zero-config, framework-agnostic, nodejs
