Thanks for the issue! This issue has been labeled as needs reproduction. This label is added to issues that need a code reproduction.

Please reproduce this issue in an Ionic starter application and provide a way for us to access it (GitHub repo, StackBlitz, etc). Without a reliable code reproduction, it is unlikely we will be able to resolve the issue, leading to it being closed.

If you have already provided a code snippet and are seeing this message, it is likely that the code snippet was not enough for our team to reproduce the issue.

Thanks for the report. Can you provide a reproduction case? I'm not able to reproduce this on my end.

This only happens when the developer preview for esbuild based building is enabled in angular.json. Vite/ESBuild is already working for Vue/React because they have been switched to CE build, but Angular still relies on Stencil lazy loading.

this happens when esbuild is triggered in the angular.json and ng serve is executed

architect: {
  "build": { /* Add the esbuild suffix */
    "builder": "@angular-devkit/build-angular:browser-esbuild",

I also have this issue when using esbuild

I have the same problem on a fresh project with Angular 16, Ionic 7.0.5, Capacitor 5.0.1. I just see a blank screen after run ng serve.

Would anyone be able to provide a minimal reproduction repo?

ESBuild is in developer preview inside of Angular (https://angular.io/guide/esbuild) and is not something we support in Ionic at the moment. See #27251 (comment) for more information.

In that case, @ooo2003003v2 can you confirm if you're able to reproduce the issue without ESBuild, and if so, provide a minimal Github repo reproducing the issue?
