fb-watchman
fb-watchman
is a filesystem watcher that uses the Watchman file watching service from Facebook.
Watchman provides file change notification services using very efficient recursive watches and also allows more advanced change matching and filesystem tree querying operations using a powerful expression syntax.

Key Concepts
Watchman recursively watches directories.
Each watched directory is called a
root
.You must initiate a
watch
on aroot
using thewatch-project
command prior to subscribing to changesRather than separately watching many sibling directories,
watch-project
consolidates and re-uses existing watches relative to a project root (the location of your.watchmanconfig
or source control repository root)change notifications are relative to the project root
