babel-plugin-macros defines a standard interface for Babel macros, letting libraries perform compile-time code transformations without users needing to configure individual Babel plugins. It is widely used by libraries like css-in-js tools to shift runtime work to build time.

Use cases

• run compile-time code transformations without configuring individual babel plugins
• optimize css-in-js libraries by generating class names at build time
• build a zero-config compile-time library for javascript
• reduce client bundle size by moving work from runtime to build time
• support macros in a create-react-app project without changing babel config

When to choose

• you maintain a library that benefits from compile-time code transformation
• you want users to get build-time optimizations with zero babel configuration
• you are using a boilerplate like create-react-app that already includes babel-plugin-macros

When to avoid

• you need language-level syntax transforms that require dedicated babel plugins
• your project does not use babel or a bundler with babel support
• you need runtime-only transformations
