## Getting Started
|
|||
|
|
|
|||
|
|
First thing's first, install the module:
|
|||
|
|
|
|||
|
|
```
|
|||
|
|
npm install postcss-syntax postcss-jsx --save-dev
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Use Cases
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
const postcss = require('postcss');
|
|||
|
|
const stylelint = require('stylelint');
|
|||
|
|
const syntax = require('postcss-syntax');
|
|||
|
|
postcss([stylelint({ fix: true })]).process(source, { syntax: syntax }).then(function (result) {
|
|||
|
|
// An alias for the result.css property. Use it with syntaxes that generate non-CSS output.
|
|||
|
|
result.content
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
input:
|
|||
|
|
```javascript
|
|||
|
|
import glm from 'glamorous';
|
|||
|
|
const Component1 = glm.a({
|
|||
|
|
flexDirectionn: 'row',
|
|||
|
|
display: 'inline-block',
|
|||
|
|
color: '#fff',
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
output:
|
|||
|
|
```javascript
|
|||
|
|
import glm from 'glamorous';
|
|||
|
|
const Component1 = glm.a({
|
|||
|
|
color: '#fff',
|
|||
|
|
display: 'inline-block',
|
|||
|
|
flexDirectionn: 'row',
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
## Advanced Use Cases
|
|||
|
|
|
|||
|
|
Add support for more `css-in-js` package:
|
|||
|
|
```js
|
|||
|
|
const syntax = require('postcss-syntax')({
|
|||
|
|
"i-css": (index, namespace) => namespace[index + 1] === "addStyles",
|
|||
|
|
"styled-components": true,
|
|||
|
|
});
|
|||
|
|
```
|
|||
|
|
|
|||
|
|

|
|||
|
|
## Style Transformations
|
|||
|
|
|
|||
|
|
The main use case of this plugin is to apply PostCSS transformations to CSS code in template literals & styles as object literals.
