Unified React styling hook

Leveraging the React Hooks API to provide an elegant, unified styling API.

One simple API based on the hooks API to style all components. Suddenly it does not matter anymore if you are using Emotion, Styled Components or JSS - the styling becomes transparent.

Great for component libraries: Don't force your users into a particular styling library! Style with universal hooks and let the users plug-in the styling library that works best for them.

Features

💅 Style components with useStyles()
💡 Uncouple components from styling library
🌅 Server side rendering
🌈 Theming support out of the box

Installation

In your app:

$ npm install react@next react-dom@next @andywer/style-hook @andywer/style-api-jss

In a component package you only need this:

$ npm install react@next @andywer/style-hook

Usage

useStyles()

// Button.js
import { useStyles } from "@andywer/style-hook"
import React from "react"

export function Button (props) {
  const classNames = useStyles({
    button: {
      padding:    "0.6em 1.2em",
      background: theme => theme.button.default.background,
      color:      theme => theme.button.default.textColor,
      border:     "none",
      boxShadow:  "0 0 0.5em #b0b0b0",
      "&:hover": {
        boxShadow: "0 0 0.5em #e0e0e0"
      }
    },
    buttonPrimary: {
      background: theme => theme.button.primary.background,
      color:      theme => theme.button.primary.textColor
    }
  })

  const className = `${classNames.button} ${props.primary ? classNames.buttonPrimary : ""}`
  return (
    <button className={className} onClick={props.onClick}>
      {props.children}
    </button>
  )
}

Rendering your app with style hook support is easy: Add a provider for the styling library at the top of your app.

// App.js
import { JssProvider } from "@andywer/style-api-jss"
import React from "react"
import ReactDOM from "react-dom"

const App = () => (
  <JssProvider>
    {/* ... */}
  </JssProvider>
)

ReactDOM.render(<App />, document.getElementById("app"))

useStyle()

This is a convenience function to define a single CSS class.

import { useStyle } from "@andywer/style-hook"
import React from "react"

export function Button (props) {
  const className = useStyle({
    padding:   "0.6em 1.2em",
    boxShadow: "0 0 0.5em #b0b0b0",
    "&:hover": {
      boxShadow: "0 0 0.5em #e0e0e0"
    }
  })
  return (
    <button className={className} onClick={props.onClick}>
      {props.children}
    </button>
  )
}

Theming & props

import { useStyles } from "@andywer/style-hook"
import React from "react"

export function Button (props) {
  const classNames = useStyles({
    button: {
      background: theme => theme.button.default.background,
      color:      theme => theme.button.default.textColor,
      border:     () => props.border || "none",
      boxShadow:  "0 0 0.5em #b0b0b0",
      "&:hover": {
        boxShadow: "0 0 0.5em #e0e0e0"
      }
    },
    buttonPrimary: {
      background: theme => theme.button.primary.background,
      color:      theme => theme.button.primary.textColor
    }
  }, [props.border])

  const className = `${classNames.button} ${props.primary ? classNames.buttonPrimary : ""}`
  return (
    <button className={className} onClick={props.onClick}>
      {props.children}
    </button>
  )
}
