Webpack Error Cannot Define Query And Multiple Loaders In Loaders List

If you're encountering the "Webpack Error: Cannot Define Query and Multiple Loaders in Loaders List" message, don't worry! This common issue can be easily resolved with a few steps to ensure your Webpack configuration runs smoothly.

### Understanding the Error:

The error message indicates that there is a conflict in your Webpack configuration where you're trying to define both a query and multiple loaders within the loaders list. This conflict causes Webpack to throw an error because it cannot interpret the configuration properly.

### Resolving the Issue:

To fix this error, you need to adjust your Webpack configuration to separate these concerns. Here's how you can do it:

1. Check Your Webpack Config File:
Open your Webpack configuration file (commonly named `webpack.config.js`) in your code editor.

2. Separate Query and Loaders:
Locate the module rules or loaders section where you define your loaders. Ensure that loaders only contain loader configurations and not queries.

3. Move Queries to the Loader Definition:
If you have queries defined in the loaders list, move them to the appropriate loader configuration. Queries are used to specify additional options for a loader, so each loader may have its own query object.

4. Review Loader Structure:
Check the structure of each loader definition to ensure it follows the correct format. Each loader should be an object with a `test` property for matching files and a `use` property for defining the loader and any associated options.

5. Restart Webpack Dev Server:
After making the necessary changes to your Webpack configuration, save the file and restart your Webpack development server to apply the updates.

### Example:

Here's an example of how you can separate queries from loaders in your Webpack configuration:

Javascript

module.exports = {
  // Other Webpack configuration settings...

  module: {
    rules: [
      {
        test: /.css$/,
        use: [
          'style-loader',
          {
            loader: 'css-loader',
            options: {
              modules: true,
            },
          },
        ],
      },
    ],
  },
};

### Conclusion:

By understanding the nature of the "Cannot Define Query and Multiple Loaders in Loaders List" error and following the steps outlined above to separate queries from loaders in your Webpack configuration, you can effectively resolve this issue and ensure that your Webpack build process proceeds without any hiccups. Don't let this error hold you back – tackle it head-on and keep coding smoothly!
