## 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
|
||||
});
|
||||
|
||||
