Can charites serve work properly on Linux?

[ubukawa]

Warm greeting! Thank you once again for the charites development!

After my work in my own PC, now I would like to share the styling work with my colleagues and use charites in Linux. I have found some issue here. I would appreciate if if you could kindly confirm it!

Describe the bug During charites serve, updated file is not detected automatically.

To Reproduce Steps to reproduce the behavior:

• Install charites on Red Hat Enterprise Linux (release 8.4)
• run "charites serve"
• Open the Charites Live Preview through http://(ip address):8080
• update yaml files under layers
• Then, edit is not detected automatically.
  • CLI does not show any message.
  • Charites Live Preview does not change.
  • (IF I type F5 on the browser, the edit is then reflected on Charites Live Preview, but no message in CLI..)

Expected behavior Even in Linux, I expected that the update/edit of yml file is automatically detected and live-view automatically update.

Screenshots If applicable, add screenshots to help explain your problem.

Charites Version:

• Charites version: 0.X.X

Desktop (please complete the following information):

• Server OS: Red Hat Enterprise Linux (release 8.4)
• Browser: Google Chrome in Windows PC (Charites is run on Linux server while I saw the preview from other PC.)

Additional context Add any other context about the problem here.

When I tried this (server: Ubuntu Linux, browser: Chrome on macOS on another PC), I got an error in the console:

WebSocket connection to: `ws://localhost:8080` failed

Because the WebSocket connection is used to tell the browser about new updates to styles, I think that this may be the culprit. A fix to dynamically change the hostname of the WebSocket connection may help?
