## Description

Babel Plugin Macros is a framework for building compile-time code transformations that modify JavaScript and TypeScript source files during the build process. It enables developers to automate repetitive code generation tasks and execute custom logic without the overhead of writing and maintaining full-scale, complex compiler plugins.

The project distinguishes itself by using import-based discovery to trigger transformation modules, allowing developers to invoke specific logic directly through standard module imports. It provides a structured environment for managing macro execution sequences and ensures predictable behavior by wrapping build-time operations in synchronous execution blocks.

The framework supports the transformation of diverse syntax nodes, including function calls and tagged template literals, to facilitate automated code generation. It also features centralized configuration management, allowing settings to be defined in standard files to maintain consistency across build tasks. To assist in development, the system includes contextual error reporting that surfaces actionable feedback directly linked to source code references when transformations fail.
