eventstore-node

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

Dependencies

• Node.js >= 0.12
• protobufjs module
• uuid module

Status

Unstable

Incomplete/missing features:

• Typed errors: currently most errors are direct instance of Error, which is not practical for error handling
• Ssl connection: Ssl connetion is not implemented yet
• Persistent subscription: create/update/delete/connec to a persistent subscription are not implemented yet
• Set system settings: not implemented yet
• 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
• NPM package: no package released yet, I will release one when code is stable

Porting .Net Task to Node.js

I used Promise to replace .Net Task, so when executing an async command, i.e. appendToStream you'll have to wait for result/error like this:

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

You will need:

• dependencies (npm install)
• nodeunit (npm install -g nodeunit)
• an instance of EventStore running on localhost:1113 (https://geteventstore.com/downloads/)

To execute the tests suites simply run test with npm

npm test
