<h1>Load Config</h1>
</div>
<h2 align="center">Install</h2>
```bash
npm i -D postcss-load-config
```
<h2 align="center">Usage</h2>
```bash
npm i -S|-D postcss-plugin
```
Install all required PostCSS plugins and save them to your **package.json** `dependencies`/`devDependencies`
Then create a PostCSS config file by choosing one of the following formats
### `package.json`
Create a **`postcss`** section in your project's **`package.json`**
```
Project (Root)
| client
| public
|
|- package.json
```
```json
{
"postcss": {
"parser": "sugarss",
"map": false,
"plugins": {
"postcss-plugin": {}
}
}
}
```
### `.postcssrc`
Create a **`.postcssrc`** file in JSON or YAML format
> It's recommended to use an extension (e.g **`.postcssrc.json`** or **`.postcssrc.yml`**) instead of `.postcssrc`
```
Project (Root)
| client
| public
|
|- (.postcssrc|.postcssrc.json|.postcssrc.yml)
|- package.json
```
**`.postcssrc.json`**
```json
{
"parser": "sugarss",
"map": false,
"plugins": {
"postcss-plugin": {}
}
}
```
**`.postcssrc.yml`**
```yaml
parser: sugarss
map: false
plugins:
postcss-plugin: {}
```
### `.postcssrc.js` or `postcss.config.js`
You may need some logic within your config.
In this case create JS file named:
- `.postcssrc.js`
- `.postcssrc.mjs`
- `.postcssrc.cjs`
- `.postcssrc.ts`
- `.postcssrc.cts`
- `postcss.config.js`
- `postcss.config.mjs`
- `postcss.config.cjs`
- `postcss.config.ts`
- `postcss.config.cts`
```
Project (Root)
| client
| public
|- (.postcssrc|postcss.config).(js|mjs|cjs|ts|cts)
|- package.json
```
You can export the config as an `{Object}`
**.postcssrc.js**
```js
module.exports = {
parser: 'sugarss',
map: false,
plugins: {
'postcss-plugin': {}
}
}
```
Or export a `{Function}` that returns the config (more about the `ctx` param below)
**.postcssrc.js**
```js
module.exports = (ctx) => ({
parser: ctx.parser ? 'sugarss' : false,
map: ctx.env === 'development' ? ctx.map : false,
plugins: {
'postcss-plugin': ctx.options.plugin
}
})
```
Plugins can be loaded either using an `{Object}` or an `{Array}`
#### `{Object}`
**.postcssrc.js**
```js
module.exports = ({ env }) => ({
...options,
plugins: {
'postcss-plugin': env === 'production' ? {} : false
}
})
```
> When using an `{Object}`, the key can be a Node.js module name, a path to a JavaScript file that is relative to the directory of the PostCSS config file, or an absolute path to a JavaScript file.
#### `{Array}`
**.postcssrc.js**
```js
module.exports = ({ env }) => ({
...options,
plugins: [
env === 'production' ? require('postcss-plugin')() : false
]
})
```
> :warning: When using an `{Array}`, make sure to `require()` each plugin
<h2 align="center">Options</h2>
|Name|Type|Default|Description|
|:--:|:--:|:-----:|:----------|
|[**`to`**](#to)|`{String}`|`undefined`|Destination File Path|
|[**`map`**](#map)|`{String\|Object}`|`false`|Enable/Disable Source Maps|
|[**`from`**](#from)|`{String}`|`undefined`|Source File Path|
|[**`parser`**](#parser)|`{String\|Function}`|`false`|Custom PostCSS Parser|
|[**`syntax`**](#syntax)|`{String\|Function}`|`false`|Custom PostCSS Syntax|
|[**`stringifier`**](#stringifier)|`{String\|Function}`|`false`|Custom PostCSS Stringifier|
### `parser`
**.postcssrc.js**
```js
module.exports = {
parser: 'sugarss'
}
```
### `syntax`
**.postcssrc.js**
```js
module.exports = {
syntax: 'postcss-scss'
}
```
### `stringifier`
**.postcssrc.js**
```js
module.exports = {
stringifier: 'midas'
}
```
### [**`map`**](https://github.com/postcss/postcss/blob/master/docs/source-maps.md)
**.postcssrc.js**
```js
module.exports = {
map: 'inline'
}
```
> :warning: In most cases `options.from` && `options.to` are set by the third-party which integrates this package (CLI, gulp, webpack). It's unlikely one needs to set/use `options.from` && `options.to` within a config file. Unless you're a third-party plugin author using this module and its Node API directly **dont't set `options.from` && `options.to` yourself**
### `to`
```js
module.exports = {
to: 'path/to/dest.css'
}
```
### `from`
```js
module.exports = {
from: 'path/to/src.css'
}
```
<h2 align="center">Plugins</h2>
### `{} || null`
The plugin will be loaded with defaults
```js
'postcss-plugin': {} || null
```
**.postcssrc.js**
```js
module.exports = {
plugins: {
'postcss-plugin': {} || null
}
}
```
> :warning: `{}` must be an **empty** `{Object}` literal
### `{Object}`
The plugin will be loaded with given options
```js
'postcss-plugin': { option: '', option: '' }
```
**.postcssrc.js**
```js
module.exports = {
plugins: {
'postcss-plugin': { option: '', option: '' }
}
}
```
### `false`
The plugin will not be loaded
```js
'postcss-plugin': false
```
**.postcssrc.js**
```js
module.exports = {
plugins: {
'postcss-plugin': false
}
}
```
### `Ordering`
Plugin **execution order** is determined by declaration in the plugins section (**top-down**)
```js
{
plugins: {
'postcss-plugin': {}, // [0]
'postcss-plugin': {}, // [1]
'postcss-plugin': {} // [2]
}
}
```
<h2 align="center">Context</h2>
When using a `{Function}` (`postcss.config.js` or `.postcssrc.js`), it's possible to pass context to `postcss-load-config`, which will be evaluated while loading your config. By default `ctx.env (process.env.NODE_ENV)` and `ctx.cwd (process.cwd())` are available on the `ctx` `{Object}`
> Most third-party integrations add additional properties to the `ctx` (e.g `postcss-loader`). Check the specific module's README for more information about what is available on the respective `ctx`
<h2 align="center">Examples</h2>
**postcss.config.js**
```js
module.exports = (ctx) => ({
parser: ctx.parser ? 'sugarss' : false,
map: ctx.env === 'development' ? ctx.map : false,
plugins: {
'postcss-import': {},
'postcss-nested': {},
cssnano: ctx.env === 'production' ? {} : false
}
})
```
