## Installation

```bash
npm i shorted-theme
```

## Usage

```ts
import styled from 'styled-components'
import shorted from 'shorted-theme'

const theme = {
  colors: {
    primary: 'red',
    secondary: 'blue'
  },
  fontFamily: '"Roboto", sans-serif',
  fontSizes: {
    small: 12,
    regular: 14,
    large: 18
  }
}

const t = shorted(theme) // 👈 short your theme then use everywhere.

const Button = styled.button`
  color: ${t.colors.primary};
  color: ${t.colors.primary};
  font-family: ${t.fontFamily};
  font-size: ${t.fontSizes.regular};
`
```

## TypeScript Support

`shorted-theme` use all your typings.

### Suggestion

You can destructure the shorted theme object. That way you can reference direct children properties instead of a root object.

```ts
const { colors, fontFamily, fontSizes } = shorted(theme)

const Button = styled.button`
  color: ${colors.primary};
  color: ${colors.primary};
  font-family: ${fontFamily};
  font-size: ${fontSizes.regular};
`
```

## Limitations

`shorted-theme` is useful for writing less when referencing theme values. However, it can't be used in expressions. For example:

```ts
// THIS WILL NOT WORK
const Button = styled.button`
  padding: ${t.padding.default * 10};
`
```

Instead you should use the function expression:

```ts
const Button = styled.button`
  padding: ${(props) => props.theme.padding.default * 10};
`
```
