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 'polishedimport polished from 'polished'
When ✨ polished modules are imported properly, tree shaking in webpack and Rollup 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 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:
[ignore]
.*/node_modules/polished/.*
TypeScript Definitions
✨ polished has TypeScript 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 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 ({ ...other }). To enable this syntax in your project add the transform-object-rest-spread plugin (or the stage-3 preset 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:
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, polished is for you.
