# eventemitter-asyncresource - AsyncResource integration for EventEmitter
|
|||
|
|
|
|||
|
|
Integrates [`EventEmitter`][] with [`AsyncResource`][] for `EventEmitter`s that
|
|||
|
|
require manual async tracking.
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
const { EventEmitterAsyncResource } = require('eventemitter-asyncresource');
|
|||
|
|
|
|||
|
|
// Async tracking tooling will identify this as 'Q'.
|
|||
|
|
const ee = new EventEmitterAsyncResource({ name: 'Q' });
|
|||
|
|
|
|||
|
|
// 'foo' listeners will run in this EventEmitter’s async context.P
|
|||
|
|
ee.emit('foo');
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
The `EventEmitterAsyncResource` class has the same methods and takes the same
|
|||
|
|
options as `EventEmitter` and `AsyncResource` themselves.
|
|||
|
|
|
|||
|
|
It provides an `.asyncResource` property that allows accessing the async
|
|||
|
|
resource in question, which in turn provides the original `EventEmitter` via
|
|||
|
|
`.eventEmitter`, i.e. in the above example
|
|||
|
|
`ee.asyncResource.eventEmitter === ee`.
