# NodeJs Event Manager
### Event Manager for both internal and external events e.g Azure Service Bus, RabbitMQ, etc.
## Basic Example
- **Initialize**
```js
// For all the initializations, It can happen on app bootup like:
/* --------- File: app.js --------- */
import EventManager from 'nodejs-event-manager';
const myEventManager = EventManager.getInstance();
// Add Azure service bus credentials
const config = {
name: 'samsoft-topic',
subscription: ['samsoft-email-sub', 'samsoft-blockchain-sub'],
connectionString: ''
};
myEventManager.initialize(config);
```
- **Consumer**
```js
// Note: You must listen before emitting any events
const listenEventMgr = EventManager.getInstance();
listenEventMgr.on('samsoft-email-sub', async (payload: EventResponse) => {
console.log({ label: payload.getSource(), body: payload.getBody() });
await payload.complete();
});
listenEventMgr.on('samsoft-email-sub:notification:send', async (payload: EventResponse) => {
console.log({ label: payload.getSource(), body: payload.getBody() });
await payload.complete();
});
```
- **Producer**
```js
/* --------- File user.activity.service.js --------- */
const senderMgr = EventManager.getInstance();
// For external event, use azure or rabbitMq
senderMgr.emit(['samsoft-blockchain-sub', 'samsoft-email-sub'], {
body: { name: 'samuel', profession: 'Software engineer' },
source: 'azure'
});
// For internal event handle, use node as source or leave blank
senderMgr.emit('samsoft-blockchain-sub:notification:send', {
body: { name: 'samuel', profession: 'Software engineer' }
source: 'node'
});
```
