## Getting started
Install the client using npm
### Install & run Eventstore on localhost
npm install eventstore-node
Examples
See http://docs.geteventstore.com/introduction/3.9.0/ .
### Example: Storing an event
TODO
1. Save to ```app.js:```
```javascript
var esClient = require('eventstore-node');
var uuid = require('uuid');
var streamName = "testStream";
var esConnection = esClient.createConnection({}, {"hostname": "localhost", "port": 1113});
esConnection.connect();
esConnection.once('connected', function (tcpEndPoint) {
console.log('Connected to eventstore at ' + tcpEndPoint.hostname + ":" + tcpEndPoint.port);
});
var eventId = uuid.v4();
var eventData = {
a : Math.random(),
b: uuid.v4()
};
var event = esClient.createJsonEventData(eventId, eventData, null, 'testEvent');
console.log("Appending...");
esConnection.appendToStream(streamName, esClient.expectedVersion.any, event)
.then(function(result) {
console.log("Stored event:", eventId);
console.log("Look for it at: http://localhost:2113/web/index.html#/streams/testStream");
esConnection.close();
})
.catch(function(err) {
console.log(err);
});
```
2. Create ```package.json```:
```json
{
"name": "hello",
"version": "1.0.0",
"main": "app.js",
"dependencies": {
"eventstore-node": "latest",
"uuid": "latest"
}
}
```
3. ```npm install```
4. ```node app.js```
## Porting .Net Task to Node.js
.Net Task have been replace with Promise. When executing an async command, i.e. appendToStream you can use then/catch to wait for result/error.
*Example*
connection
.appendToStream('myStream', client.expectedVersion.any, events, userCredentials)
.then(function(result) {
//Do something with the WriteResult here
})
.catch(function(err) {
//Handle error here
});
## Running the tests
To run the tests you will need
