Erreur indicateur '--jsx'

Erreur indicateur '--jsx' is an error that can occur when using the React library. It indicates that the React library has not been properly configured and is not able to parse JSX code. JSX (JavaScript XML) is a syntax extension to JavaScript that allows developers to write HTML-like syntax within their JavaScript code. It is used to define the structure of a React component, such as its props, state, and other features.

The '--jsx' error occurs when the React library fails to parse the JSX code. This can happen if the React library is not properly configured, or if there is a syntax error within the JSX code. To resolve this issue, you can either configure the React library properly, or correct any syntax errors in the JSX code.

To configure the React library, you can use the webpack-config.js file. This file is responsible for configuring the React library and is usually located in the root directory of your project. The webpack-config.js file contains the following code:

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

This code tells the React library how to parse the JSX code. It tells the library to use the Babel loader to parse any JSX code. This should resolve the '--jsx' error.

If there are any syntax errors in the JSX code, you can use a linter to detect them. A linter is a tool that checks your code for any syntax errors. It can detect any incorrect syntax and alert you about it. Once you have fixed the syntax errors, the '--jsx' error should be resolved.
