🐛 Update: Added support for the 'find' command in settings.local.json. Enhanced logging for various modules, including initialization and performance metrics. Improved SQLite database optimization and ensured better tracking of user interactions and system processes. 📚

# Emitter [](https://travis-ci.org/component/emitter)
|
||||
|
||||
Event emitter component.
|
||||
|
||||
## Installation
|
||||
|
||||
```
|
||||
$ component install component/emitter
|
||||
```
|
||||
|
||||
## API
|
||||
|
||||
### Emitter(obj)
|
||||
|
||||
The `Emitter` may also be used as a mixin. For example
|
||||
a "plain" object may become an emitter, or you may
|
||||
extend an existing prototype.
|
||||
|
||||
As an `Emitter` instance:
|
||||
|
||||
```js
|
||||
var Emitter = require('emitter');
|
||||
var emitter = new Emitter;
|
||||
emitter.emit('something');
|
||||
```
|
||||
|
||||
As a mixin:
|
||||
|
||||
```js
|
||||
var Emitter = require('emitter');
|
||||
var user = { name: 'tobi' };
|
||||
Emitter(user);
|
||||
|
||||
user.emit('im a user');
|
||||
```
|
||||
|
||||
As a prototype mixin:
|
||||
|
||||
```js
|
||||
var Emitter = require('emitter');
|
||||
Emitter(User.prototype);
|
||||
```
|
||||
|
||||
### Emitter#on(event, fn)
|
||||
|
||||
Register an `event` handler `fn`.
|
||||
|
||||
### Emitter#once(event, fn)
|
||||
|
||||
Register a single-shot `event` handler `fn`,
|
||||
removed immediately after it is invoked the
|
||||
first time.
|
||||
|
||||
### Emitter#off(event, fn)
|
||||
|
||||
* Pass `event` and `fn` to remove a listener.
|
||||
* Pass `event` to remove all listeners on that event.
|
||||
* Pass nothing to remove all listeners on all events.
|
||||
|
||||
### Emitter#emit(event, ...)
|
||||
|
||||
Emit an `event` with variable option args.
|
||||
|
||||
### Emitter#listeners(event)
|
||||
|
||||
Return an array of callbacks, or an empty array.
|
||||
|
||||
### Emitter#hasListeners(event)
|
||||
|
||||
Check if this emitter has `event` handlers.
