How to make a reverse proxy on a specific route properly?

Help

1. The problem I’m having:

I’m trying to make a reverse proxy to localhost on a specific route in my app. Let’s say we have a route named /app that should forward to localhost:3000 with the following code:

localhost {
  handle /app {
    reverse_proxy: http://localhost:3000
  }
}

Then caddy forwards /app to my app while it expects / to be the root. I tried to use the strip_prefix function like this:

localhost {
  handle /app {
    uri strip_prefix /app
    reverse_proxy: http://localhost:3000
  }
}

But then redirects don’t work. Should I do something to fix them or does caddy have some more built in way to handle this better?

2. Error messages and/or full log output:

I’d say it’s relevant because I don’t think that reverse_proxy: syntax you’re using it correct.
