Research direction

Start by reproducing the reported ng serve --host 0.0.0.0 --disable-host-check setup through the forwarded /proxy/4200/ URL. Investigate how the basehref and servepath options affect Angular node-resource URLs and redirects, including the duplicated /proxy/4200/ case. Done means the forwarded dev server loads those resources without an incorrect path.

Command

serve

Is this a regression?
  • Yes, this behavior used to work in the previous version
The previous version in which this bug was not present was

before vite

Description

I provide remote training for Angular using VSCode in the browser.
It is no longer possible to use the vscode port forwarding to access the ng dev server as basehref and servepath combinations to not yield the correct result when @angular node resources are to be loaded. It works for all other assets/files in the project.

Minimal Reproduction

Use code-server oder vscode server access through web browser.

ng new
ng serve --host 0.0.0.0 --disable-host-check

Open the forwarded port, URL becomes f.e.
https://student01.remote-training.de/proxy/4200/

I tried various configuration combinations using prebundle, basehref and servepath only to experience worse problems like beeing redirected to https://student01.remote-training.de/proxy/4200/proxy/4200/
