## Installation

`npm i --save react-css-themes`

## Usage [API]

#### `withThemes(themeTypes, [themes], [defaultTheme])`

##### Arguments:

- `themeTypes` *(`Object`)* - Theme types definition
- `themes` *(`Object`)* - The available themes
- `defaultTheme` *(`Object`)* - The default theme

##### Returns:

Returns a decorator `function to make Component themeable.

##### Example:

```js
import React from 'react'
import withThemes, { ThemeTypes } from 'react-css-themes'

import light from './light.css'
import dark from './dark.css'

const ThemableComponent = ({ theme }) => (


Heading


)

ThemableComponent.themeTypes = {
container: ThemeTypes.className,
heading: ThemeTypes.className
}

export default withThemes({ light, dark }, light)(ThemableComponent)
```

#### `ThemeTypes`

`ThemeTypes` are used to define theme's property types. It's simillar to React `PropTypes`, there are 2 avaiable types:

- `ThemeTypes.className`: Defines a property as a className
- `ThemeTypes.themeOf(ThemableComponent)`: Define a property as a theme of another themeable compoenent

##### Example:

```js
import React from 'react';
import { ThemeTypes } from 'react-css-themes'

function MyComponent ({ theme }) {
// ... do things with the props
}

MyComponent.themeTypes = {
themeProp: ThemeTypes.className,
childComponent: ThemeTypes.themeOf(ThemableComponent),
}
```

### `Component.themes`

The compoenent will expose a `themes` object property with the themes defined as keys. These themes are set by the compoenent but also expose an API to create derivated themes.

#### `add(fragment)`

##### Arguments:

- `fragment` *(`Object`)* - ClassNames to add to the theme

##### Returns:

A new theme derived from the original theme plus the fragment

##### Example:

```js

let ThemableComponent = ({ theme }) => (


)

ThemableComponent = withThemes({
light: {
container: '.container'
}
}, light)(ThemableComponent)

/* HTML output */

renderToStaticMarkup()
//

// Derived theme
const theme = ThemableComponent.themes.light.add({
container: '.foobar'
})

renderToStaticMarkup()
//


```

## Examples

### Basic theming

```js
/* ThemableComponent.js */
import React from 'react'
import withThemes, { ThemeTypes } from 'react-css-themes'

import light from './light.css'
import dark from './dark.css'

const ThemableComponent = ({ theme }) => (


Heading


)

ThemableComponent.themeTypes = {
container: ThemeTypes.className,
heading: ThemeTypes.className
}

export default withThemes({ light, dark }, light)(ThemableComponent)
```

```css
/* light.css */
.container {
background-color: white;
}
.heading {
color: black;
}
```

```css
/* dark.css */
.container {
background-color: black;
}
.heading {
color: white;
}
```

```js
/* View.js */
import React from 'react'
import ThemableComponent from './ThemableComponent'

const View = () => (




/* Default theme (light) will be used */

)

export default View
```

### Composing themable components

```js
/* AnotherThemableComponent.js */
import React from 'react'
import withThemes, { ThemeTypes } from 'react-css-themes'

import themeA from './themeA.css'
import themeB from './themeB.css'

const THEMES = {
themeA: {
...themeA,
child1: ThemableComponent.themes.light,
child2: ThemableComponent.themes.dark
},
themeB: {
...themeB,
child1: ThemableComponent.themes.dark,
child2: ThemableComponent.themes.light
}
}

const AnotherThemableComponent = ({ theme }) => (





)

AnotherThemableComponent.themeTypes = {
container: ThemeTypes.className,
child1: ThemeTypes.themeOf(ThemableComponent),
child2: ThemeTypes.themeOf(ThemableComponent)
}

export default withThemes(THEMES, THEMES.themeA)(AnotherThemableComponent)
```

### Adding `classNames` to a deeply nested themeable child

```js
/* AnotherThemableComponent.js */
import React from 'react'
import withThemes, { ThemeTypes } from 'react-css-themes'

import themeA from './themeA.css'

const THEMES = {
themeA: {
...themeA,
child: ThemableComponent.themes.light.add({
container: themeA.childContainer,
heading: themeA.childHeading
})
}
}

const AnotherThemableComponent = ({ theme }) => (




)
```
