vite-plugin-importmap

Vite plugin (v0.1.1) that enables import map-like path resolution by environment variable (mark). Allows conditional module replacement per build target using string suffix conventions, arrays, or JSON config files. Unlike standard Vite resolve aliases, it switches between file variants based on a single mark. Minimal API surface, ESM-only, ships TypeScript definitions. Release cadence is low; single maintainer. Suitable for multi-tenant or configurable builds.
