Configuration File Loader Tool

Build a utility that loads and displays Babel configuration information from a JavaScript project.

Requirements

Your tool should:

1. Accept a directory path as input
2. Load the Babel configuration for that directory
3. Display information about the configuration, including:
   • Whether a configuration file was found
   • The path to any configuration files discovered
   • The list of plugins configured
   • The list of presets configured
4. Handle cases where no configuration exists gracefully
5. Export a function loadBabelConfig(dirPath) that returns an object with the configuration details

Output Format

The function should return an object with this structure:

{
  hasConfig: boolean,        // true if config was found
  configFiles: string[],     // array of config file paths found
  plugins: string[],         // array of plugin names
  presets: string[]         // array of preset names
}

If no configuration is found, return an object with hasConfig: false and empty arrays for the other fields.

Test Cases

• Loading config from a directory with babel.config.js returns correct plugin and preset names @test
• Loading config from a directory with .babelrc returns correct configuration details @test
• Loading config from a directory without Babel config returns hasConfig: false @test
• Config loading handles the package.json "babel" field correctly @test

Implementation
