babel-plugin-module-name-mapper

Babel plugin that adds Jest-like moduleNameMapper support to Babel, enabling import path rewriting with special tokens <pkgDir> and <rootDir>. <pkgDir> resolves to the directory of the closest package.json, making it ideal for monorepos. Current stable version is 1.2.0. Release cadence is low; maintained. Key differentiator: supports <pkgDir> for monorepo-friendly path resolution, which is lacking in Jest and Webpack. Alternative to babel-plugin-module-resolver with different token semantics.
