<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))
}))
```
