I am creating a react app without using npx create-react-app, i am using webpack, and trying to use the tailwind CSS, with it. But getting error.

How should I do confugration the to the react app so that I can use tailwind in this ?

error:

ERROR in ./index.css 1:0
Module parse failed: Unexpected character '@' (1:0)
You may need an appropriate loader to handle this file type, currently no loaders are configured to process this file. See https://webpack.js.org/concepts#loaders
> @tailwind base;
| @tailwind components;
| @tailwind utilities;
 @ ./index.js 4:0-21

webpack 5.75.0 compiled with 1 error in 43 ms

Index.css in react app:

@tailwind base;
@tailwind components;
@tailwind utilities;

index.js of react app

import React from "react";
import ReactDOM from "react-dom/client";
import App from "./src/App";
import "./index.css";

const root = ReactDOM.createRoot(document.getElementById("root"));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

my webpack file:

CodePudding user response：

Can you also provide the tailwind.config.js?

Also there are postcss library installed in package.json, the doc says there’re no support with postcss library in create react app. Please check here.

https://tailwindcss.com/docs/guides/create-react-app

CodePudding user response：

You have to add postcss loader (which will pick up the config with tailwind) to the use chain of loaders in module.rules with test: /\.(css|sass)$/i.
