Babel Plugin Configuration Manager

A utility that demonstrates integration with the Babel plugin ecosystem by creating a configurable transformation pipeline.

Capabilities

Plugin Configuration

Build a system that correctly configures and applies the block-scoped functions transformation plugin along with related Babel plugins.

• Given a JavaScript source file containing block-scoped function declarations, the configuration manager applies the transformation plugin and returns the transformed code @test
• When multiple plugins are configured in sequence, the manager applies them in the correct order and produces properly transformed output @test
• The manager correctly detects and handles strict mode contexts when applying transformations @test

Plugin Metadata Integration

Integrate with Babel's plugin metadata system to coordinate transformations.

• When async generator functions are present, the manager correctly reads and uses plugin metadata to ensure proper transformation @test
