馃殌 Feature request

I want to use --base-url with --dev-server-target in ng e2e, but it results a following error:

The 'baseUrl' option cannot be used with 'devServerTarget'.

I want to use them together in the following case:

  • Let ng e2e launch the server (--serve) and then run protractor.
    • --serve feature is really useful as protractor starts after the server gets ready.
  • protractor controls a browser in another host with webdriver protocol.

In that case, the browser have to access the server not with http://localhost:4200/ which is automatically configured with ng e2e --dev-app-server, but with http://(appropriate host name):4200/.

I created a demonstration project to explain what I want:

Describe the solution you'd like

I want to use --base-url to specify that host name.

Relates: #13611, #13614

Describe alternatives you've considered

Accepting --public-host in ng e2e can resolve this issue.
(It results Unknown option: '--public-host' for now)

Relates: #9242

Hi @ikedam, it looks to me that the problem is that the command you are running is

npm run e2e --host= --port=4200 --protractor-config=e2e/protractor-docker.conf.js

while to achieve the desired behaviour you need

npm run e2e --host=angular --protractor-config=e2e/protractor-docker.conf.js

@alan-agius4 You're right.
Specifying a host name in --host instead of resolves my issue: ikedam/angular-e2e-base-url-demo@ffcf1d8
(You also need to set up the environment to allow angular resolve the host name to IP address)

Thanks a lot!
