npm i @shgysk8zer0/importmap

// rollup.config.js
import { rollupImport } from '@shgysk8zer0/rollup-import';
import { imports } from '@shgysk8zer0/importmap';

export default {
	input: 'index.js',
	output: {
		file: 'index.min.js',
		format: 'iife',
		sourcemap: true,
	},
	plugins: [rollupImport({ imports })],
};

The module exports getImportMapScript(), which can be used to generate the required importmap <script>:

import { getImportMapScript } from '@shgysk8zer0/importmap';

getImportMapScript();

Which results in:

<script type="importmap" integrity="sha384-...">{"imports": {}, "scope": {}}</script>
