Hello, is there a plan to handle this issue? Or is there any temporary patching method?

webpack/webpack-dev-server#5443

[alexander-akait]

@lzxb it is not a bug, it is how multiple entries work, your configuration is wrong and no need to patch something

The answer is here - webpack/webpack-dev-server#5443 (comment)

@chenjiahan I think you can close this issue

[chenjiahan]

Thank you, I have converted this issue to a discussion since it's not a bug

[lzxb]

@alexander-akait I'm using Rspack's entry and externals to build an importmap-based application. Each entry compiles into an ESM module, and the externals configuration links different exported modules together. This serves as the foundation for building large-scale micro-frontend applications based on ESM.

[lzxb]

This is the simplest example of building an ESM micro-frontend application.

I created a project at https://github.com/esmnext/esmx and planned to implement it, but got stuck on hot updates for multiple entry points.

@lzxb Did you read my comments how multiple entries work? You can't use multiple runtimes on the same page

[alexander-akait]

You mix libraries and applications, vue is a library and don't need runtime at all for it, main.ts is an application, but you are using everything as separate pages, like you have vue.html/app.html/main.html, there are no fixes, it is a wrong configuration

app.vue can't work without vue, main.ts can't work without app.vue, but you don't specify it
