export default defineConfig({
  plugins: [
    fastExternal({

      // custom external code by function

    })
  ]
})

  externals: Record<string, string | (() => string)>,
  options?: {
    /**
     * @default 'esm'
     * esm will generate code - const vue = window['Vue']; export { vue as default };

How to work

1. External-module will be generated code into node_modules/.vite-plugin-fast-external/xxxx.js
2. Append an external-module alias

{
  resolve: {
    alias: [
      {
        find: 'vue',
        replacement: 'User/work-directory/node_modules/.vite-plugin-fast-external/vue.js',
      },
    ],
  },
}
