|
|---|
| 2 |
|
|---|
| 3 | `fb-watchman` is a filesystem watcher that uses the
|
|---|
| 4 | [Watchman](https://facebook.github.io/watchman/) file watching service from
|
|---|
| 5 | Facebook.
|
|---|
| 6 |
|
|---|
| 7 | Watchman provides file change notification services using very
|
|---|
| 8 | efficient recursive watches and also allows more advanced change matching and
|
|---|
| 9 | filesystem tree querying operations using
|
|---|
| 10 | [a powerful expression syntax](https://facebook.github.io/watchman/docs/file-query.html#expressions).
|
|---|
| 11 |
|
|---|
| 12 | ## Install
|
|---|
| 13 |
|
|---|
| 14 | You should [install Watchman](
|
|---|
| 15 | https://facebook.github.io/watchman/docs/install.html) to make the most of this
|
|---|
| 16 | module.
|
|---|
| 17 |
|
|---|
| 18 | Then simply:
|
|---|
| 19 |
|
|---|
| 20 | ```
|
|---|
| 21 | $ npm install fb-watchman
|
|---|
| 22 | ```
|
|---|
| 23 |
|
|---|
| 24 | ## Key Concepts
|
|---|
| 25 |
|
|---|
| 26 | - Watchman recursively watches directories.
|
|---|
| 27 | - Each watched directory is called a `root`.
|
|---|
| 28 | - You must initiate a `watch` on a `root` using the `watch-project` command prior to subscribing to changes
|
|---|
| 29 | - 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)
|
|---|
| 30 | - change notifications are relative to the project root
|
|---|
| 31 |
|
|---|
| 32 | ## How do I use it?
|
|---|
| 33 |
|
|---|
| 34 | [Read the NodeJS watchman documentation](https://facebook.github.io/watchman/docs/nodejs.html)
