how to use astroturf in project with styled-components

[r-tsvetkov]

hi guys!
I have some misunderstanding
how to use together babel-loader & astroturf/loader
when moving from styled-components to astroturf.

In my case, when I configure webpack like this:

{
    test: /.(js|jsx)$/,
    exclude: /node_modules/,
    use: ['babel-loader', 'astroturf/loader'],
    resolve: {
    extensions: ['.js', '.jsx'],
  },
}

astroturf works correctly, but breaks styled-components

when I swap them

use: ['astroturf/loader', 'babel-loader'],

styled-components works, but astroturf breaks

do you have any ideas how to solve this problem?
thank you in advance!

In what way does it break? It should "just work" with SC if everything is configured correctly

thank you for your answer
yes, I also thought it was strange that two similar technologies didn't work together
here is my config

.babelrc

{
  "presets": ["@babel/preset-env", "@babel/preset-react"],
  "plugins": ["astroturf/plugin"]
}

webpack.config.js

const HtmlWebpackPlugin = require("html-webpack-plugin");
const path = require("path");

const config = {
  entry: "./src/index.js",
  output: {
    path: path.resolve(__dirname, "dist"),
    filename: "bundle.js",
  },
  devServer: {
    port: 3003,
  },
  module: {
    rules: [
      {
        test: /\.(js|jsx)$/,
        use: ["babel-loader", "astroturf/loader"],
        exclude: /node_modules/,
      },
      {
        test: /\.css$/,
        use: ["style-loader", "astroturf/css-loader"],
      },
    ],
  },
  plugins: [
    new HtmlWebpackPlugin({
      template: "./src/index.html",
    }),
  ],
  resolve: {
    extensions: [".js", ".jsx"],
  },
};

module.exports = config;

App.js

import React from "react";
import styled from "astroturf";

const StyledH1 = styled.h1`
  color: red;
`;

const App = () => <StyledH1>Hello world!</StyledH1>;

export default App;

in that case (import styled from "astroturf";) its works
but if astroturf change to styled-components

Uncaught Error: Objects are not valid as a React child (found: object with keys {$$typeof, render, attrs, componentStyle, shouldForwardProp, foldedComponentIds, styledComponentId, target, withComponent, warnTooManyClasses, toString}). If you meant to render a collection of children, use an array instead.

do I need to configure postcss for astroturf to work correctly? or what am I doing wrong? 😄
