A pleasure to have importmap during development. No webpack, esbuild, bundlers. Compile TypeScript, start web server (like python3 -m http.server ...), point browser to some HTML file like:

<head>
<script type="importmap">
{
"imports": {
"chai": "../../node_modules/chai/index.js",
}
}
</script>
<script type="module" src="../../build/DavIntegrationTest.js"></script>

<script type="importmap"> - HTML | MDN

The importmap value of the type attribute of the <script> element indicates that the body of the element contains an import map.
