[Dev UI] Allow to expose dev-ui on other context than /

[cmarchand]

Description

Using virtual dev-env like Coder allows to code / run Quarkus applications. But Dev-Ui is not usable for 2 reasons :

• dev-ui is limited to localhost : this can be changed with quarkus.dev-ui.hosts
• dev-ui is exposed on / context-root

In coder, when one choose a port-forwarding to expose 8080 outside of dev-env, port is exposed on an URL like https://.../.../.../apps/code-server/proxy/8080/ ; if I add q/dev-ui to this URL, I can load index.html file, but it references js files with an absolute context :

• /q/_static/es-module-shims/2.0.10/dist/es-module-shims.js
• /q/dev-ui/icon/font-awesome.js
• etc...

If this resources were loaded with a relative path, this would allow to load dev-ui from another context-root :

• ../_static/es-module-shims/2.0.10/dist/es-module-shims.js
• ./icon/font-awesome.js
• etc...

I'd be happy to contribute, but I'm lost in sources, and can not find where the templating engine is call. Any hint will be appreciated.

@cescoffier : we met at JavaDay, and I had a question on this subject...

[phillip-kruger]

@cmarchand can you help me to create an reproducer for this ? Then I can look at it

[cmarchand]

Yes. I can build a VM for this, and give you credentials to access to it, via PM.

Is this Ok for you ?

[phillip-kruger]

Yeah or just instructions on how to get to that point

[cmarchand]

That's the most difficult point for me !

Could you give me an email address, or a Keeper account, to share you accesses ?
