On Linux,
--watchstopped restarting after the first time a watched file was replaced via unlink+create or rename (atomic saves,docker compose watch, bind mounts), so it appeared to "only reload the first time".filterFilewatched each file directly, which binds the inotify watch to the file's inode.On replacement the old inode is unlinked: the watch fires once, then dies; the new file's inode is never watched.
Fix: watch the parent directory non-recursively instead of the file. The directory inode is stable across replacements, and unrelated siblings are still discarded by the filter-mode check in
#onChange. macOS/Windows alreadywatched the directory and were unaffected.
