I just started to have a look at the htmlui. When I start it, it tried to access the api at [http://localhost:3000/api/v1/](http://localhost:3000/api/v1/)
Is there somewhere documentation how to setup a dev environment?

What do you mean by “dev environment”? Do you want to setup a test server or do you really want to mess with the code?

My plan is to _“mess with the code”_ … in case I’ve got some spare time… There are some things in the UI I’d like to give it a try if I could improve.
(One thing that’s in my mind: It’s so nice that I can mount a directory from any snapshot in the UI with a single click. But it happened to me now that I forgot which directory I did mount so I had to click around a bit before checking `mount` from the CLI. So I thought it would be nice to keep a list of mounted directories in the UI accessible. Maybe add a new tab that is only visible when there are mounts.)
But after starting `react-scripts start` the UI just shows “Request failed with status code 504” as it tries to access the API at localhost:3000/api. And of course there is nothing running. So I expect that some more setup is needed which might be part of a different project.

What worked for me was to fork Kopia on GH to my own account and then setting up Github on my target machine - in this case a Linux box, using the Github repo and rpms.
Then I checked out my fork of Kopia where I had performed my changes to test them out. Getting gh to work is essential, since it pulls-in a lot of dependencies.

In one terminal do:
```auto
$ cd kopia
$ go run . server start --insecure --without-password --disable-csrf-token-checks --log-level=debug
```
In another:
```auto
$ cd htmlui
$ npm run start
```
You can now access kopia UI on `localhost:3000`

So now I did “mess” a little with the code: [Added directory breadcrumb buttons to see path and navigate back](https://github.com/kopia/htmlui/pull/141)
Would be nice to know if this goes in a direction that you’d approve.
