# fb-watchman
|
|
|
|
`fb-watchman` is a filesystem watcher that uses the
|
|
[Watchman](https://facebook.github.io/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](https://facebook.github.io/watchman/docs/file-query.html#expressions).
|
|
|
|
## Install
|
|
|
|
You should [install Watchman](
|
|
https://facebook.github.io/watchman/docs/install.html) to make the most of this
|
|
module.
|
|
|
|
Then simply:
|
|
|
|
```
|
|
$ npm install fb-watchman
|
|
```
|
|
|
|
## Key Concepts
|
|
|
|
- Watchman recursively watches directories.
|
|
- Each watched directory is called a `root`.
|
|
- You must initiate a `watch` on a `root` using the `watch-project` command prior to subscribing to changes
|
|
- Rather 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
|
|
|
|
## How do I use it?
