不使用构建工具，本地app能用importmap吗

[stirwl]

<script src="vue.global.prod.js"></script>可以载入本地文件。

因为vue示例大多使用import方式，所以我也想用这种方式
但importmap不能导入本地文件。

<script type="importmap"> { "imports": { "vue": "./vue.esm-browser.js" } } </script>

Failed to load module script: Expected a JavaScript-or-Wasm module script but the server responded with a MIME type of "". Strict MIME type checking is enforced for module scripts per HTML spec.

Hi @stirwl,

Most likely you're opening the HTML file directly from your folder, right? So the URL starts with file://.

Browsers have this security thing where they block module scripts loaded that way, because there's no server to tell them it's a real JavaScript file (that's the MIME type error you're seeing).

Easiest fix is to run a simple local server. You don't need any build tools. Since you're working with JS, you probably have Node.js/npm installed. Just open a terminal in your project folder and run:

npx serve

It will start a server and give you a URL like http://localhost:3000. Open that in your browser and it should work.

The "Live Server" extension in VS Code is also a super easy way to do this if you use that editor.

Hope that helps
