babel-plugin-system-import-transformer

Babel plugin that transforms System.import() calls (and import() since v3) into a UMD-compatible pattern using Promise. Originally for Babel 5/6, now supports Babel 7 (v4). Key differentiator: it generates a runtime pattern that works across AMD, CommonJS, and global module formats without requiring a module bundler. Stable version 1.1.5 (legacy) with newer major versions for Babel 6 (v2) and Babel 7 (v4). Automatically detects module target (amd/commonjs) and strips unnecessary format detection. Maintenance mode; consider dynamic import with webpack/rollup instead.
