Functions watcher Appears Not to Work

[ronen25]

Bug report

Describe the bug

After running supabase functions serve on a newly-created hello function, I expect to see the function hot-reload after changing the index.ts file of the function, but nothing seems to happen.

I see this message which indicates that serve worked, but again, hot-reloading the function does not seem to work:

Starting supabase/functions/hello
Serving supabase/functions/hello
Watcher Process started.
Hello from Functions!

To Reproduce

1. Run supabase functions new hello
2. Leave everything as-is in the index.ts file
3. Run supabase start
4. Run supabase functions serve hello
5. See 'Hello Functions!' printed - expected result.
6. Make any change in index.ts - for this example I made a change to the output message
7. 'Hello functions' is still printed, instead of the new output message. Also, there appears to be no status updates from the watcher.

Expected behavior

Expected the function to hot-reload.

System information

• OS: [e.g. macOS, Windows] Windows 11
• Browser (if applies) [e.g. chrome, safari] Independent
• Versions: CLI version 0.24.2, Deno: deno 1.20.4 (release, x86_64-pc-windows-msvc) v8 10.0.139.6 typescript 4.6.2 supabase-js: 1.33.3
• Version of Node.js: v16.14.0

Additional context

Tried running serve from an Administrative Powershell and Admin. CMD - same result.

This seems to be a limitation of Docker on Windows: https://forums.docker.com/t/file-system-watch-does-not-work-with-mounted-volumes/12038

The workaround mentioned in that thread is to do the file watching ourselves natively, but that involves a lot of work - happy to hear any alternatives.

Facing the same issue...

There's an old post that works for others but I can't get this to work. Anyone more luck?

@soedirgo This seems to be caused by the incorrect path being exposed:

WARNING:root:Bind of container supabase_deno_relay_edge-functions was skipped since it has invalid source path C:\supabase\examples\edge-functions/supabase/functions

Notice the change in backslash to slash. The Python script would work if the mount would be 'correct'

EDIT: I did it! AAAAAAH! This makes my life so much easier dealing with Edge Functions. Wow.

Steps to get to the same outcome:

1. Go to https://github.com/merofeev/docker-windows-volume-watcher and download the source
2. Change the file container_monitor.py to the following contents: https://pastebin.com/raw/07uxv9gG You can read more about these changes in this issue: https://github.com/merofeev/docker-windows-volume-watcher/issues/18
3. Download auto-py-to-exe here https://github.com/brentvollebregt/auto-py-to-exe
4. Start auto-py-to-exe and create a new exe file from the cli.py file
5. Start the cli.exe
6. Success!

Good find! The mount path thing is a bug - will work on a fix.

hey , a guest from the dystopian '23 here 😀.

Hi! Just here to ask for any updates in the issue. Still persist up to date.

I hate to do this, but I third the request to prioritize fixing this issue.

issue on Docker macOs too

[AakashKB]

Still facing this issue on Mac. Even stopping/restarting supabase does not pickup new function changes. @Bijig0 did you ever solve for mac?

Unfortunately not, I personally switched to vercel cloud functions

I can confirm that I'm experiencing the same issues. A full Docker restart is required to run updates locally on mac.
