## Getting Started

First thing's first, install the module:

```
npm install postcss-syntax @stylelint/postcss-css-in-js --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
});
```

See: [postcss-syntax](https://github.com/gucong3000/postcss-syntax)

## Style Transformations

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