Babel Configuration Inspector

A command-line tool that inspects and reports on Babel configuration files in a project directory.

Capabilities

Load configuration information

Load Babel configuration for a given file path and provide detailed information about the configuration source, options, and file paths.

• When provided with a project directory path and a target file path, the tool loads the Babel configuration and returns an object containing configuration file paths (config file, babelrc file, babelignore file) and whether the file should be ignored. @test

Handle projects without configuration

Gracefully handle projects that have no Babel configuration files.

• When provided with a directory that contains no Babel configuration files, the tool returns null to indicate no configuration was found. @test

Report configuration options

Extract and display the resolved configuration options that would be used for transpilation.

• When configuration is found, the tool extracts and returns the resolved options including any presets and plugins that would be applied. @test
