# Neat Components

A Styled Components implementation of Thoughtbot's Neat 2.0.

View Storybook examples here: https://magicink.github.io/neat-components/

### Usage

```javascript
import React, { Component } from 'react'
import styled, { ThemeProvider } from 'styled-components'
import Neat, { gridContainer, gridColumn, gridShift } from 'neat-components'

let constants = () => {
  return `
    background-color: blue;
    height: 50px;
    margin-top: 1em;
  `
}

let Container = styled.div`
  ${gridContainer()};
`
let Column = styled.div`
  ${constants()} ${props => gridColumn(props.theme, 1)};
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <div>
          <Container>
            <Column />
            <Column />
            <Column />
            <Column />
          </Container>
        </div>
      </ThemeProvider>
    )
  }
}

export default App
```

## API

### Neat([settings])

Returns a theme object. You can pass this theme to a `ThemeProvider` component. For example

```javascript
<ThemeProvider theme={Neat()}>...</ThemeProvider>
```

You can pass in a `settings` object to create a custom grid. The `settings` object has the following properties:

**`color`**: Used by `gridVisual()` to determine the color the grid (default: `null`).

**`columns`**: The number of columns the grid supports (default: `12`).

**`direction`**: The direction columns float. Accepts `ltr` (default) or `rtl`.

**`gutter`**: The spacing between columns (default: `20px`)

**`media`**: Used by `gridMedia()` to specify the media the grid should be applied. It can accept a string (i.e. `only screen and (max-width: 800px)`) or a number (i.e `800`). The later would produce `only screen and (min-width: 800px)`. Defaults to `null`.

```javascript
const CustomGrid = Neat({ columns: 3, gutter: '60px' })
const Container = styled.div`
  margin-top: 1rem;
  ${gridContainer()};
`
const WideColumn = styled.div`
  background-image: linear-gradient(to bottom right, #21e9f4, #00d4ff);
  border-radius: 5px;
  height: 20rem;
  ${props => gridColumn(props.theme, 1)};
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <Container>
          <WideColumn theme={CustomGrid} />
          <WideColumn theme={CustomGrid} />
          <WideColumn theme={CustomGrid} />
        </Container>
      </ThemeProvider>
    )
  }
}
```

### gridCollapse(theme)

Used to create grids within grids.

```javascript
const SidebarGrid = Neat({
  columns: 3,
  gutter: '40px'
})

const GalleryGrid = Neat({
  columns: 4,
  gutter: '40px'
})

const Container = styled.div`
  ${gridContainer()};
`

const SideBar = styled.div`
  height: 19rem;
  ${props => gridColumn(SidebarGrid, 1)};
`

const Gallery = styled.div`
  ${props => gridColumn(GalleryGrid, 2)};
`

const GalleryContainer = styled.div`
  ${gridCollapse(GalleryGrid)} ${gridContainer()};
`

const GalleryItem = styled.div`
  background-color: #496278;
  height: 4rem;
  margin-bottom: 1rem;
  ${gridColumn(GalleryGrid, 1)};
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <Container>
          <SideBar />
          <Gallery>
            <GalleryContainer>
              <GalleryItem />
              ...
            </GalleryContainer>
          </Gallery>
        </Container>
      </ThemeProvider>
    )
  }
}
```

### gridColumn(theme, span)

Creates a component that occupies `span` number of a given theme's columns

```javascript
let Column = styled.div`
  ${props => gridColumn(props.theme, 1)};
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <div>
          <Container>
            <Column />
            <Column />
            <Column />
            <Column />
          </Container>
        </div>
      </ThemeProvider>
    )
  }
}
```

### gridContainer()

Injects a clearfix solution into the component.

```javascript
const Container = styled.div`
  ${gridContainer()};
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <Container>...</Container>
      </ThemeProvider>
    )
  }
}
```

### gridMedia(theme)

Used to inject media queries into the component.

```javascript
const mobileGrid = Neat({
  columns: 12,
  gutter: '10px',
  media: 'only screen and (max-width: 600px)'
})

const desktopGrid = Neat({
  columns: 12,
  gutter: '20px',
  media: 'only screen and (min-width: 601px)'
})

const Column = styled.div`
  height: 50px;
  background-color: yellow;
  margin-top: 1rem;
  ${gridColumn(mobileGrid, 2)}
  ${gridMedia(desktopGrid, [
    {
      ...gridColumn(desktopGrid, 1),
      'background-color': 'red'
    }
  ])}
`

const Container = styled.div`
  ${gridContainer()}
`

export class GridMedia extends React.Component {
  render() {
    return [
      <h1 key={'header'}>
        <code>gridMedia</code>
      </h1>,
      <ThemeProvider key={'provider'} theme={Neat()}>
        <Container>
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
          <Column />
        </Container>
      </ThemeProvider>
    ]
  }
}
```

### gridShift(theme, shift)

Shifts a component `shift` number of columns. This reorganizes the components..

```javascript
let constants = () => {
  return `
    background-color: blue;
    height: 50px;
    margin-top: 1em;
  `
}

let Container = styled.div`
  ${gridContainer()};
`
let Column = styled.div`
  ${constants()} ${props => gridColumn(props.theme, 1)};
`

let Shifted = styled.div`
  ${constants()}
  ${props => gridColumn(props.theme, 1)}
  ${props => gridShift(props.theme, 2)}
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <div>
          <Container>
            <Column />
            <Shifted /> // Shifted one column to the right.
          </Container>
        </div>
      </ThemeProvider>
    )
  }
}
```

### gridPush(theme, push)

Pushes the component `push` number of columns. It's similar to `gridShift()` but does not rearrange the components.

```javascript
let constants = () => {
  return `
    background-color: blue;
    height: 50px;
    margin-top: 1em;
  `
}

let Container = styled.div`
  ${gridContainer()};
`
let Column = styled.div`
  ${constants()} ${props => gridColumn(props.theme, 1)};
`

let Pushed = styled.div`
  ${constants()}
  ${props => gridColumn(props.theme, 1)}
  ${props => gridPush(props.theme, 2)}
`

class App extends Component {
  render() {
    return (
      <ThemeProvider theme={Neat()}>
        <div>
          <Container>
            <Column />
            <Pushed /> // Pushed one column to the right.
          </Container>
        </div>
      </ThemeProvider>
    )
  }
}
```

### gridVisual(theme)

Creates series of visual guidelines based on the grid system.
