rails-react syntax error jsx not enabled

Step 1: Install necessary dependencies

# Run these commands in your terminal
npm install --save babel-loader @babel/core @babel/preset-react

Step 2: Create a Babel configuration file Create a file named .babelrc in your project root directory with the following content:

  "presets": ["@babel/preset-react"]

Step 3: Configure Webpack to use Babel-loader Update your Webpack configuration to include the babel-loader. In your webpack.config.js file, add the following rule to the module.rules array:

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

Step 4: Check file extensions Ensure your React components have the ".jsx" file extension. For example, if your component is named "MyComponent," the file should be named "MyComponent.jsx."

Step 5: Restart your development server After making these changes, restart your development server to apply the new configurations.

If you still encounter issues, make sure your React components use JSX syntax and are properly formatted.
