  <h1>Load Options</h1>
</div>

<h2 align="center">Install</h2>

```bash
npm i -D postcss-load-options
```
<h2 align="center">Usage</h2>

### `package.json`

Create **`postcss`** section in your projects **`package.json`**.

```
App
  |– client
  |– public
  |
  |- package.json
```

```json
{
  "dependencies": {
    "sugarss": "0.2.0"
  },
  "postcss": {
    "parser": "sugarss",
    "map": false,
    "from": "path/to/src/file.css",
    "to": "path/to/dest/file.css"
  }
}
```

### `.postcssrc`

Create a **`.postcssrc`** file.

```
App
  |– client
  |– public
  |
  |- (.postcssrc|.postcssrc.json|.postcssrc.yaml)
  |- package.json
```

**`JSON`**
```json
{
  "parser": "sugarss",
  "map": false,
  "from": "path/to/src/file.css",
  "to": "path/to/dest/file.css"
}
```

**`YAML`**
```yaml
parser: sugarss
map: false
from: "/path/to/src.sss"
to: "/path/to/dest.css"
```

### `postcss.config.js` or `.postcssrc.js`

You may need some JavaScript logic to generate your config. For this case you can use a file named **`postcss.config.js`** or **`.postcssrc.js`**.

```
App
  |– client
  |– public
  |
  |- (postcss.config.js|.postcssrc.js)
  |- package.json
```

```js
module.exports = (ctx) => {
  return {
    parser: ctx.sugar ? 'sugarss' : false,
    map: ctx.env === 'development' ? ctx.map || false,
    from: 'path/to/src/file.css',
    to: 'path/to/dest/file.css'
  }
}
```

<h2 align="center">Options</h2>

**`parser`**:

```js
'parser': 'sugarss'
```

**`syntax`**:

```js
'syntax': 'postcss-scss'
```
**`stringifier`**:

```js
'stringifier': 'midas'
```

[**`map`**:](https://github.com/postcss/postcss/blob/master/docs/source-maps.md)

```js
'map': 'inline'
```

**`from`**:

```js
from: 'path/to/dest/file.css'
```

**`to`**:

```js
to: 'path/to/dest/file.css'
```

### Context

When using a function `(postcss.config.js)`, it is possible to pass context to `postcss-load-options`, which will be evaluated before loading your options. By default `ctx.env (process.env.NODE_ENV)` and `ctx.cwd (process.cwd())` are available.

<h2 align="center">Example</h2>

### <img width="80" height="80" src="https://worldvectorlogo.com/logos/nodejs-icon.svg">

```js
const { readFileSync } = require('fs')

const postcss = require('postcss')
const optionsrc = require('postcss-load-options')

const sss =  readFileSync('index.sss', 'utf8')

const ctx = { sugar: true,  map: 'inline' }

optionsrc(ctx).then((options) => {
  postcss()
    .process(sss, options)
    .then(({ css }) => console.log(css))
}))
```
