Hi everyone,
I have a problem with postCSS: it works with extract: true and not with extract: false; inject:true

Here is my rollup.config.js

import commonjs from "@rollup/plugin-commonjs"
import peerDepsExternal from "rollup-plugin-peer-deps-external"
import typescript from "rollup-plugin-typescript2"
import postcss from "rollup-plugin-postcss"
import packageJson from "./package.json"
import { terser } from "rollup-plugin-terser"
import progress from "rollup-plugin-progress"
import { visualizer } from "rollup-plugin-visualizer"

export default [
  {
    input: ["src/index.ts", "src/inputs/index.ts"],
    output: [
      {
        dir: "dist",
        format: "cjs",
        exports: "auto",
        sourcemap: false
      }
    ],
    preserveModules: true,
    plugins: [
      progress(),
      peerDepsExternal(),
      commonjs(),
      typescript({ useTsconfigDeclarationDir: true }),
      postcss({
        extract: true,
        minimize: true,
        modules: true
      }),
      terser(),
      visualizer({})
    ],
    external: [...Object.keys(packageJson.peerDependencies || {}), ...Object.keys(packageJson.dependencies || {})]
  }
]

Here is my TextField.tsx

import React from "react"
import classnames from "classnames"
import ITextFieldProps from "./TextField.types"
import style from "./TextField.module.scss"

const TextField: React.FC<ITextFieldProps> = (props: ITextFieldProps) => {
  return <div className={classnames("text-field", style.textField)}>{props.name}</div>
}

export default TextField

Here is my TextField.module.scss

@import "../../style/variables.scss";

.textField {
  background-color: $color;
}
