1 | # eventemitter-asyncresource - AsyncResource integration for EventEmitter
|
---|
2 |
|
---|
3 | Integrates [`EventEmitter`][] with [`AsyncResource`][] for `EventEmitter`s that
|
---|
4 | require manual async tracking.
|
---|
5 |
|
---|
6 | ```js
|
---|
7 | const { EventEmitterAsyncResource } = require('eventemitter-asyncresource');
|
---|
8 |
|
---|
9 | // Async tracking tooling will identify this as 'Q'.
|
---|
10 | const ee = new EventEmitterAsyncResource({ name: 'Q' });
|
---|
11 |
|
---|
12 | // 'foo' listeners will run in this EventEmitter’s async context.P
|
---|
13 | ee.emit('foo');
|
---|
14 | ```
|
---|
15 |
|
---|
16 | The `EventEmitterAsyncResource` class has the same methods and takes the same
|
---|
17 | options as `EventEmitter` and `AsyncResource` themselves.
|
---|
18 |
|
---|
19 | It provides an `.asyncResource` property that allows accessing the async
|
---|
20 | resource in question, which in turn provides the original `EventEmitter` via
|
---|
21 | `.eventEmitter`, i.e. in the above example
|
---|
22 | `ee.asyncResource.eventEmitter === ee`.
