Watch globs and execute a function upon change, with intelligent defaults for debouncing and queueing.
## Usage
```js
var watch = require('glob-watcher');
watch(['./*.js', '!./something.js'], function(done){
// This function will be called each time a globbed file is changed
// but is debounced with a 200ms delay (default) and queues subsequent calls
// Make sure to signal async completion with the callback
// or by returning a stream, promise, observable or child process
done();
// if you need access to the `path` or `stat` object, listen
// for the `change` event (see below)
// if you need to listen to specific events, use the returned
// watcher instance (see below)
});
// Raw chokidar instance
var watcher = watch(['./*.js', '!./something.js']);
// Listen for the 'change' event to get `path`/`stat`
// No async completion available because this is the raw chokidar instance
watcher.on('change', function(path, stat) {
// `path` is the path of the changed file
// `stat` is an `fs.Stat` object (not always available)
});
// Listen for other events
// No async completion available because this is the raw chokidar instance
watcher.on('add', function(path, stat) {
// `path` is the path of the changed file
// `stat` is an `fs.Stat` object (not always available)
});
```
## API
### `watch(globs[, options][, fn])`
Takes a path string, an array of path strings, a [glob][micromatch] string or an array of [glob][micromatch] strings as `globs` to watch on the filesystem. Also optionally takes `options` to configure the watcher and a `fn` to execute when a file changes.
__Note: As of 5.0.0, globs must use `/` as the separator character because `\\` is reserved for escape sequences (as per the Bash 4.3 & Micromatch specs). This means you can't use `path.join()` or `__dirname` in Windows environments. If you need to use `path.join()`, you can use [normalize-path][normalize-path] against your paths afterwards. If you need to use `__dirname`, you can set it as the `cwd` option that gets passed directly to [chokidar][chokidar]. The [micromatch docs][micromatch-backslashes] contain more information about backslashes.__
Returns an instance of [chokidar][chokidar].
#### `fn([callback])`
If the `fn` is passed, it will be called when the watcher emits a `change`, `add` or `unlink` event. It is automatically debounced with a default delay of 200 milliseconds and subsequent calls will be queued and called upon completion. These defaults can be changed using the `options`.
The `fn` is passed a single argument, `callback`, which is a function that must be called when work in the `fn` is complete. Instead of calling the `callback` function, [async completion][async-completion] can be signalled by:
* Returning a `Stream` or `EventEmitter`
* Returning a `Child Process`
* Returning a `Promise`
* Returning an `Observable`
Once async completion is signalled, if another run is queued, it will be executed.
#### `options`
##### `options.ignoreInitial`
If set to `false` the `fn` is called during [chokidar][chokidar] instantiation as it discovers the file paths. Useful if it is desirable to trigger the `fn` during startup.
__Passed through to [chokidar][chokidar], but defaulted to `true` instead of `false`.__
Type: `Boolean`
Default: `true`
##### `options.delay`
The delay to wait before triggering the `fn`. Useful for waiting on many changes before doing the work on changed files, e.g. find-and-replace on many files.
Type: `Number`
Default: `200` (milliseconds)
##### `options.queue`
Whether or not a file change should queue the `fn` execution if the `fn` is already running. Useful for a long running `fn`.
Type: `Boolean`
Default: `true`
##### `options.events`
An event name or array of event names to listen for. Useful if you only need to watch specific events.
Type: `String | Array<String>`
Default: `[ 'add', 'change', 'unlink' ]`
##### other
Options are passed directly to [chokidar][chokidar].
