rollup-plugin-import-map

A Rollup plugin to apply import map mappings during the build process, enabling module resolution according to the WICG import map specification. Current stable version is v3.0.0 (ESM-only, supports Rollup 3). There is also a v4.0.0-next.1 pre-release with full import map support but significant API changes. The plugin wraps the `@import-maps/generate` library to resolve bare specifiers to URLs defined in an import map JSON. It is one of few Rollup plugins that implement import map resolution, distinct from `@rollup/plugin-node-resolve` which resolves to node_modules. Release cadence has been low; breaking changes between major versions require migration attention.
