## What it is
Treat is a themeable, statically extracted CSS-in-JS library that executes style files at build time via a webpack plugin, producing near-zero runtime CSS. It is now deprecated in favor of its successor, Vanilla Extract.

## Use cases
- write type-safe styles in TypeScript with static CSS extraction
- theme a React app with near-zero runtime CSS
- generate static CSS files from JavaScript at build time
- support legacy browsers with class-swapping theming
- keep CSS logic out of the production JavaScript bundle

## When to choose
- maintaining an existing codebase already built on treat
- studying how static CSS extraction works before migrating to Vanilla Extract

## When to avoid
- starting a new project - use Vanilla Extract instead
- projects not using webpack
- teams needing actively maintained tooling or community support

## Facets
- artifact type: library
- maturity: abandoned
- function: css-framework, build-tool, theme
- domain: web-development, frontend, developer-tools
- platform: cross-platform
- tags: css-in-js, static-css-extraction, webpack-plugin, theming, deprecated, typescript, nodejs, web-server
