Can you explain the role of
<script type="importmap"><script type="importmap">
{
"imports": {
"three": "https://example.com/3dstuff/three.module.js"
}
}
</script>
In the past, simply including this line would make Three.js work seamlessly, but now it seems that it is essential to use importmap:
<script type="module"> import * as THREE from "https://example.com/3dstuff/three.module.js";
Your code's importmap creates a shortcut linking the string "three" to the corresponding .js file URL. To properly write your
<script type="module">import * as three from "three";Source: https://github.com/WICG/import-maps:
When supplying the browser with the following import map:
<script type="importmap">
{
"imports": {
"moment": "/node_modules/moment/src/moment.js",
"lodash": "/node_modules/lodash-es/lodash.js"
}
}
</script>
The above would function similarly to:
import moment from "/node_modules/moment/src/moment.js";
import { partition } from "/node_modules/lodash-es/lodash.js";
With the introduction of import maps, developers now have the ability to effortlessly bring external code into their projects without relying on a build tool. This innovative feature also ensures that the imported code is only loaded when necessary during runtime. While import maps may not entirely replace the need for build tools which are crucial for tasks like styling sheets and image handling, they do provide a swift and convenient way to kickstart new JavaScript applications by leveraging the inherent capabilities of web browsers.
