Getting Started

First thing's first, install the module:

npm install postcss-syntax @stylelint/postcss-css-in-js --save-dev

Use Cases

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:

import glm from "glamorous";
const Component1 = glm.a({
  flexDirectionn: "row",
  display: "inline-block",
  color: "#fff"
});

output:

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:

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.
