eventstore-node

A port of the EventStore .Net ClientAPI to Node.js

Dependencies

Node.js >= 0.12
Modules: long, protobufjs, uuid (installed via npm install)

Status

Unstable

Missing features:

Ssl connection
Cluster connection
Set system settings

Incomplete

Typed errors: currently most errors are direct instance of Error, which is not practical for error handling
Performance: there's still some while loop in the code that could be problematic with node.js
Tests: tests are only covering happy path scenarios for now

Getting started

Install the client using npm

npm install eventstore-node

Examples

TODO

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

To install the dependencies (npm install)
Run an instance of EventStore >= 3.3.0 (competing consumers are required for test) on localhost:1113 (Download here)

To execute the tests suites simply run test with npm

npm test
