Anvil App Server behind reverse proxy on subpath

Anvil Q&A
1

I am trying to put my anvil apps behind my nginx reverse proxy. I have been able to make this work with a subdomain, but would like to use subpaths instead.

I am running multiple anvil apps and would like to put them on subpaths so I don’t have to create a separate subdomain for each.

Does anybody have any ideas how I might achieve this?

Cheers

Do you want to access the apps like this?
App 1:
Public url: https://app1.mydomain.com
Internal url: http://192.168.1.10:3000

App 2:
Public url: https://app2.mydomain.com
Internal url: http://192.168.1.20:3000

I have one of my apps running as a docker container in CasaOS

This is my reverse proxy settings on my Synology NAS:

In my router I have a port forward for 443 which points to my Synology NAS (100.0.0.10)

As I have understand. The argument —ip 0.0.0.0 is important (to make app accessible within LAN) and also —orgin https://xyz.mydomain.com (it’s important that this matches the reverse proxy domain otherwise anvil will through errors)

No. I already have my nginx setup to make this work. I want to remove the need for additional subdomains for each app all-together.
So apps are accessed via:
App1: https://mydomain.com/app1
App2: https://mydomain.com/app2

Hi @bohdan,

I’m afraid there is no way to do this with Anvil. All apps must have their own domains or subdomains in order to benefit from cross-domain isolation provided by browsers.

I’m not looking to do this but I’m curious - isn’t “anvil.works/build” an Anvil app hosted on a subpath? Or am I mistaken
