Use native browser import-maps in vite. What's import-maps
Simply add import-maps plugin in vite.config
// vite.config.js
const { defineConfig } = require('vite')
const { importMaps } = require('vite-plugin-import-maps')
module.exports = defineConfig({
plugins: [
importMaps([
{
imports: {
lodash: 'https://esm.sh/[email protected]',
},
},
]),
],
})
Then your module will import from cdn instead of vite pre-bundle module.
Cuz it use native import-maps, itt also allow you to use module in runtime.
<!-- index.html -->
<script type="module">
import _, { isNaN } from 'lodash'
console.log(_.isNaN(NaN)) // true
console.log(isNaN(NaN)) // true
</script>
Until now, only Chrome implements the import-maps feature. But it is easy to use a polyfill with es-module-shims.
And to be ware, due to there is no way for vite to unresolve bare moduleId now, this plugin use an alia with the preifx /@import-maps/
, which means import 'lodash'
will transform to import '/@import-maps/lodash'
.
