For module-federation need to use output auto

const { defineConfig } = require('@vue/cli-service')
const webpack = require('webpack')

module.exports = defineConfig({
  configureWebpack: {
    output: {
      publicPath: 'auto', // <- ERROR: Avoid modifying webpack output.publicPath directly. Use the "publicPath" option instead.
    },
    optimization: {
      splitChunks: false,
    },
    plugins: [
      new webpack.container.ModuleFederationPlugin({
        name: 'vue_cli_demo',
        filename: 'remoteEntry.js',
        exposes: {
          './HelloWorld.vue': './src/components/HelloWorld.vue',
        },
        shared: {
          vue: {
            singleton: true,
          },
        },
      }),
    ],
  },
  transpileDependencies: true
})

Fix problem for

• external_"app2":1 Uncaught (in promise) ScriptExternalLoadError: Loading script failed. module-federation/module-federation-examples#307
• webpack module federation doesn't work after vue-cli@5.0.0-beta.3 #6823

after that I'll add example here

• Add example vue3 cli module-federation/module-federation-examples#1632

https://next.cli.vuejs.org/config/#publicpath VueConfig has option for this.

Local: http://localhost:8082/auto

But... I'm checking at the moment, seems MF is working...

Last time it confused me and I went looking for a workaround

FYI: @sodatea ?

@AndreiSoroka sorry I'm not member of contributor group. Maybe ask others to determine.

Thanks for the PR.
But I think there are still many places that we need to fix for publicPath: 'auto' to work correctly.

For example, process.env.BASE_URL should be set to '' in this case. So does the baseUrl argument for genHistoryApiFallbackRewrites.

After applying those changes, I think it would be more consistent to replace the options.publicPath here with process.env.BASE_URL, too.

thanks. I will update mr on this week

@sodatea Hi, can you re-review the code?
