# Why TSS

[![](https://github.com/garronej/tss-react/workflows/ci/badge.svg?branch=main) ](https://github.com/garronej/tss-react/actions)[![](https://img.shields.io/npm/dw/tss-react) ](https://www.npmjs.com/package/tss-react)[![](https://img.shields.io/npm/l/tss-react)](https://github.com/garronej/tss-react/blob/main/LICENSE)

'tss-react' is intended to advantageously replace the now deprecated [@material-ui v4 makeStyles](https://material-ui.com/styles/basics/#hook-api) and [react-jss](https://cssinjs.org/react-jss/?v=v10.9.0) by providing much better TypeScript support.

* ✅ Seamless integration with [MUI](https://mui.com) and [material-ui v4](https://v4.mui.com/).
* ✅ [`withStyles`](https://v4.mui.com/styles/api/#withstyles-styles-options-higher-order-component) API support.
* ✅ [JavaScript support](https://github.com/garronej/tss-react/issues/28).
* ✅ Server side rendering support (e.g: Next.js, Gatsby).
* ✅ Offers [a type-safe equivalent of the JSS `$` syntax](/v3-1/nested-selectors.md).
* ✅ Custom `@emotion` cache support.
* ✅ Build on top of [`@emotion/react`](https://emotion.sh/docs/@emotion/react), it has very little impact on the bundle size alongside MUI (\~5kB minziped).
* ✅ [Maintained for the foreseeable future](https://github.com/mui-org/material-ui/issues/28463#issuecomment-923085976), issues are dealt with within good delays.
* ✅ As fast as `emotion` ([see the difference](https://stackoverflow.com/questions/68383046/is-there-a-performance-difference-between-the-sx-prop-and-the-makestyles-functio) with MUI's `makeStyles`)
* ✅ Library authors:  [`tss-react` won’t be yet another entry in your `peerDependencies`](https://docs.tss-react.dev/publish-a-module-that-uses-tss).
