README
📦 ui-box is a low level CSS-in-JS solution that focuses on being simple, fast and extensible. All CSS properties are set using simple React props, which allows you to easily create reusable components that can be enhanced with additional CSS properties. This is very useful for adding things like margins to components, which would normally require adding non-reusable wrapper elements/classes.
## Install
```shell
yarn add ui-box
# or
npm install --save ui-box
```
## Usage
```jsx
import Box from 'ui-box'
function Button(props) {
return
}
function Example() {
return (
Hi
)
}
```
The above example component renders a red, disabled `` with margins.
### API
#### Box (default export)
##### is
Type: `string` or React component type
Default: `'div'`
Lets you change the underlying element type. You can pass either a string to change the DOM element type, or a React component type to inherit another component. The component just needs to accept a `className` prop to work. A good example is inheriting the [react-router `Link` component](https://reacttraining.com/react-router/web/api/Link).
E.g:
```jsx
Login
```
##### clearfix
Type: `boolean`
Utility property for easily adding clearfix styles to the element.
##### className
Type: `string`
The className prop you know and love. Internally it gets enhanced with additional class names for the CSS properties you specify.
##### selectors
Type: `object`
This prop allows you to define selectors and custom styles to apply when the selector condition is met. This can be used to create richer element interactions, such as hover or focus states, without the use of another css-in-js library.
```tsx
Hello world
```
##### CSS properties
All of these CSS properties are supported. You can pass either a string or a number (which gets converted to a `px` value). The shorthand properties with repeated values only accept a single value, e.g. `margin="10px"` works but `margin="10px 20px"` does not. You can use the x/y props (e.g. `marginX`/`marginY`) to achieve the same thing.

##### Other props
All other props passed through to the underlying DOM element / React component.
#### extractStyles()
Returns a `{ cache, styles }` object which contains the cache entries and rendered styles for server rendering. The styles can be output in a `` tag or an external stylesheet (however you want). The cache should be passed to `hydrate()` on the client-side before mounting the app. Also useful for doing snapshot unit testing (make sure to call `clearStyles()` after each test though).
#### hydrate(cache)
Hydrates the cache using the `cache` value returned from `extractStyles()`. This is used to prevent needing to recalculate all the class names and re-render all the styles on page load when server rendering.
#### clearStyles()
Clears the cache and removes the rendered styles. Mainly useful for resetting the global state when using `extractStyles()` in unit tests.
#### splitProps(props, keys)
Utility function for filtering out props based on an array of keys. Returns an `{ matchedProps, remainingProps }` object.
##### props
Type: `object`
##### keys
Type: `array[string]`
#### splitBoxProps(props)
Utility function for filtering out `Box` props. Returns an `{ matchedProps, remainingProps }` object.
##### props
Type: `object`
#### keyframes(name, timeline)
Function for generating an animation keyframe name and injecting the provided styles into the stylesheet. The `timeline` object is in the shape of `{ 'from' | 'to' | [0-100]: CssProps }` which define the styles to apply at each position of the animation. Returns the generated name for use with the `animation` or `animationName` props.
```tsx
import Box, { keyframes } from 'ui-box'
const openAnimation = keyframes('openAnimation', {
from: {
opacity: 0,
transform: 'translateY(-120%)'
},
to: {
transform: 'translateY(0)'
}
})
const AnimatedBox = () => <Box animation={`${openAnimation} 240ms cubic-bezier(0.175, 0.885, 0.320, 1.175)`} />
// Equivalent using individual props:
const AnimatedBox = () => (
<Box
animationName={openAnimation}
animationDuration={240}
animationTimingFunction="cubic-bezier(0.175, 0.885, 0.320, 1.175)"
/>
)
```
#### propTypes
Object of all the `Box` CSS property `propTypes`.
#### propNames
Array of all the `Box` CSS property names.
#### propAliases
Array of the `Box` CSS property aliases (the shorthand properties).
#### propEnhancers
Object of all the CSS property enhancers (the methods that generate the class name and styles for each property).
#### Enhancer groups
These enhancer groups are also exported. They're all objects with `{ propTypes, propAliases, propEnhancers }` properties. They're mainly useful for if you want to inherit a subset of the `Box` CSS propTypes in your own components.
- `animation`
- `background`
- `borderRadius`
- `borders`
- `boxShadow`
- `dimensions`
- `flex`
- `interaction`

### Classname prefix
By default `ui-box` uses `ub-` as the classname prefix before all ui-box generated classnames. You can alter this by using `setClassNamePrefix('whatever-you-want-')`. Note that the delimiter is included in the prefix... this is to support backwards compatibility with the old classnames (< v3), which you can achieve using something like this:
```js
import { setClassNamePrefix } from 'ui-box'
setClassNamePrefix('📦')
```
### Safe `href`s
By default `ui-box` ensures that urls use safe protocols when passed to an element. We built this functionality into `ui-box` to protect the end users of the products you are building. You can opt-out of this by using `configureSafeHref({enabled?: boolean, origin?: string})`. This allows you to configure which protocols are acceptable (`http:`, `https:`, `mailto:`, `tel:`, and `data:`) and that the correct `rel` values are added (`noopener`, `noreferrer`(for external links)).
```js
import { configureSafeHref } from 'ui-box'
configureSafeHref({
enabled: true // the default behavior
})
```
```js
import { configureSafeHref } from 'ui-box'
configureSafeHref({
enabled: true
origin: 'https://app.segmentio.com',
})
```
Additionally you can override the behavior on an individual component basis using the prop `allowUnsafeHref`
```jsx
<Box is="a" href="javascript:alert('hi')" allowUnsafeHref>
This is unsafe
</Box>
```
### Server side rendering
To render the styles on the server side just use [`ReactDOMServer.renderToString()`](https://reactjs.org/docs/react-dom-server.html#rendertostring) as usual and then call the [`extractStyles()`](#extractstyles) method retrieve the rendered styles and cache. The styles can then be output to a `<style>` tag or an external stylesheet. The cache data should be passed to the [`hydrate()`](#hydratecache) method on the client side before you call [`ReactDOM.hydrate()`](https://reactjs.org/docs/react-dom.html#hydrate).
For example:
```js
'use strict'
const React = require('react')
const ReactDOMServer = require('react-dom/server')
const { default: Box, extractStyles } = require('.')
const element = React.createElement(Box, { margin: '10px', color: 'red' }, 'hi')
const html = ReactDOMServer.renderToString(element)
const { styles, cache } = extractStyles()
const page = `
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8" />
<title>Page</title>
<style>
${styles}
${html}
${JSON.stringify(cache)}
