src alias in vite/vue project with @ symbol not working-CodePudding

I have installed Vue3/TS project with Vite CLI

My vite.config.ts looks like this:

import vue from '@vitejs/plugin-vue'
import { defineConfig } from 'vite'
import path from 'path'

export default defineConfig({
    plugins: [vue()],

    resolve: {
        alias: {
            '@': path.resolve(__dirname, './src'),
        },
    },
})

Also I add 'paths' property inside tsconfig.json:

{
    "compilerOptions": {
        ...
        "baseUrl": "./",
        "paths": {
            "@/*": ["./src/*", "./dist/*"]
        }
    },
    "include": ["src/**/*.ts", "src/**/*.d.ts", "src/**/*.tsx", "src/**/*.vue"]
}

With this setup '@' alias works fine with simple component importing. But in my case, I was needed in dynamic import with template strings:

<script setup lang="ts">
import { useStore } from '@/store/app'
import { computed, defineAsyncComponent } from 'vue'

const store = useStore()
const userRole = store.getUserRole

const component = computed(() => {
    return defineAsyncComponent(
        () => import(`@/components/pages/dashboard/${userRole}.vue`)
    )
})
</script>

This sample throw an error:

Uncaught (in promise) TypeError: Failed to resolve module specifier '@/components/pages/dashboard/admin.vue' at dashboard.vue:14:54

If I replace '@' with dot-notation - it works fine. Need your help)

Try like this:

resolve: {
  alias: {
    '@': path.resolve(__dirname, 'src'),
  }
}

Your alias definition is fine, but you are missing a details about importing dynamic assets with Vite. I already explained it in this answer (for Vue but we are talking about Vite's behavior here).

This is due to Rollup Limitations. All imports must start relative to the importing file and import should not start with a variable.

You have to replace the alias (@/) with relative or absolute path ./components or /src/components as you already did:

const component = computed(() => {
    return defineAsyncComponent(
        () => import(`./components/pages/dashboard/${userRole}.vue`)
    )
})
