Vue2 Vite prod boundle not working

[matutorm]

Hello,
I am migrating Vue2 application from Webpack to Vite and I am facing errors in production boundle. Build finish with no errors, but when I run it in Chrome, all inherited functionality from parent component do not work.

For example I have Vue.directive('dataTestAttr', dataTestAttr) and when I build component without property-decoration this directive works as it should, but when I use property-decoration I get Failed to resolve directive: data-test-attr error, same thing happens when I try to extend another component instead of Vue, all inherited methods doesnt work and I get Error in v-on handler: "TypeError: e.myMethod is not a function" ...

Am I doing something wrong or is there a known problem with the vite / rollup? Thank you!

Component

<script lang="ts">
import { Component,  Vue } from 'vue-property-decorator'

@Component({
  name: 'BaseInput',
})
export default class BaseInput extends Vue{
}
</script>

<template>
  <div v-data-test-attr="{ value: `test` }" class="base-image">
    Test
  </div>
</template>

Vite.config.js

import vue from '@vitejs/plugin-vue2'

const path = require('path')

export default {
  resolve:{
    alias:{
      '@' : path.resolve(__dirname, './src')
    },
  },
  plugins: [vue()],
  css: {
    preprocessorOptions: {
      scss: {
        additionalData: `@import "./src/assets/scss/app.scss";`
      }
    }
  },
  build: {
    lib: {
      entry: path.resolve(__dirname, 'src/index.ts'),
      name: 'TestPackage',
      fileName: (format) => `test-package-ui.${format}.js`,
      sourcemap: true,
    },
    rollupOptions: {
      external: ['vue', 'vue-class-component', 'vue-property-decorator'],
      output: {
        globals: {
          vue: 'Vue',
          'vue-class-component': 'vue-class-component',
          'vue-property-decorator': 'vue-property-decorator',
        },
      }
    }
  }
}

Any idea how to solve this? 👀

Try removing the property-decorator package from the external option. I have a similar setup and it works fine, except that I keep the decorator in the build.
