A lightweight toolset for writing styles in JavaScript. ✨  [](https://codecov.io/gh/styled-components/polished) [](https://npmcharts.com/compare/polished) ```sh npm install --save polished # or if you're using yarn yarn add polished ``` Want to write styles in JavaScript, but also want Sass-style helper functions and mixins? Need a consistent color palette throughout your app? `✨ polished` is for you! - **Make your app look great without stress** - **Cross framework compatible**: No matter if you're using [`styled-components`](https://github.com/styled-components/styled-components), emotion, jss, aphrodite, radium, or plain inline styles, as long as you're writing your styles in JavaScript you can use polished! - **Switching from a pre-processor to styles in JS made easy** ## Docs **See the full documentation at [polished.js.org](http://polished.js.org/docs)!** ## Usage `✨ polished` modules are meant to be used as stand-alone imports. You should avoid importing the entire library directly: `import { clearFix, animation } from 'polished'` ~`import * as polished from 'polished`~ ~`import polished from 'polished'`~ When `✨ polished` modules are imported properly, tree shaking in [webpack](https://webpack.js.org/guides/tree-shaking/) and [Rollup](https://github.com/rollup/rollup#tree-shaking) can be leveraged to reduce your bundle size. ## Browser Support All Evergreen Browsers + IE11 As of v3.6.X we support `>0.5%, not dead, ie >= 11, not op_mini all` for all our builds. ## Flow Type Definitions `✨ polished` has first-class [Flow](https://flow.org/) support with zero configuration to assist you in finding type errors while using our modules. ### Ignore ✨ polished source Flow frequently updates and it is possible that the version you are running may cause you to run into errors coming from the `polished` package in your `node_modules` directory. You can add the following lines to your `.flowconfig` to ignore `polished` in those cases: ```bash [ignore] .*/node_modules/polished/.* ``` ## TypeScript Definitions `✨ polished` has [TypeScript](https://www.typescriptlang.org/) definitions to allow the library to be used in any TypeScript project. You will need to set `moduleResolution` to `node` in your `tsconfig.json` in order to use `✨ polished` with TypeScript. ### Babel plugin You can optionally also use [`babel-plugin-polished`](https://github.com/styled-components/babel-plugin-polished) to compile the static function calls out and remove the (already tiny) runtime performance impact of using `✨ polished`. ### Object Spread Properties In the documentation you will see examples using [object spread properties](https://github.com/tc39/proposal-object-rest-spread) (`{ ...other }`). To enable this syntax in your project add the [`transform-object-rest-spread` plugin](https://www.npmjs.com/package/babel-plugin-transform-object-rest-spread) (or the [`stage-3` preset](https://babeljs.io/docs/plugins/preset-stage-3/) to enable all stage three features) to your Babel configuration. ## Why? When writing styles in JavaScript, many people need Sass-style helper functions to be productive. `✨ polished` brings them to you in a nice, lightweight package tailor-made for styles in JavaScript. The main difference with Sass is that it's written in a functional style and all color functions are curried. This means you can compose them together into your own reusable helpers with a `compose` function of your choice: ```JS import { compose } from 'ramda' // Replace with any compose() function of your choice import { lighten, desaturate } from 'polished' // Create tone() helper const tone = compose(lighten(0.1), desaturate(0.1)) ``` ### Why not `package-xyz`? First of all, we didn't find another library that had everything we needed, and we don't care about installing a dozen packages separately. Specifically most other packages that provide color functions do so in an object-oriented style, often with a fluent API that's very different from the Sass-style helpers. This means people that aren't very familiar with JavaScript might shy away from using them. `✨ polished` was made as a standard library for everybody, no matter if they know JS inside out or not. ## Compatibility ✨ polished is **compatible with any library that accepts styles as JS objects**. This includes, but is by far not limited to, `styled-components`, radium, aphrodite, glamor, glamorous, jss and many more! No matter if you're using [inline styles or CSS-in-JS](http://mxstbr.blog/2016/11/inline-styles-vs-css-in-js/), polished is for you. ## Contributors This project exists thanks to all the people who contribute.
