# Observable Base Class
|
||
|
|
|
||
|
|
The `Observable` base class makes and subclass trigger events and accept event listeners.
|
||
|
|
|
||
|
|
### Example
|
||
|
|
|
||
|
|
```js
|
||
|
|
class Test extends Observable {
|
||
|
|
doSomething() {
|
||
|
|
// work
|
||
|
|
this.trigger('work-done', {some: params})
|
||
|
|
}
|
||
|
|
}
|
||
|
|
|
||
|
|
let test = new Test();
|
||
|
|
test.on('work-done', (params) => yay());
|
||
|
|
```
|
||
|
|
|
||
|
|
### With Sockets
|
||
|
|
|
||
|
|
You can also bind sockets (SocketIO) to an `Observable` and all events will also be emitted or received via the socket. See the API below for binding sockets.
|
||
|

|
- `once(event, listener)`: trigger an event once
