Events from nodeJS

Step 1: Add dependencies in package.json

In your package.json, include the following in dependencies

"dependencies": {
  ...
  "datacoral-slice-event-tracker-nodejs": "https://datacoral.com/instrumentation/nodejs/1.0.0/datacoral-slice-event-tracker-nodejs.tgz"
}

Step 2: Sample nodeJS Instrumentation

You will receive the following information about your events slice:

  1. Event Slice Endpoint
  2. API Keys for different environments
// Initialize the tracker

var datacoral = require('datacoral-slice-event-tracker-nodejs');
var emitter = datacoral.emitter;
var tracker = datacoral.tracker;

// Initialize an emitter instance. This object will be responsible for how and when events are sent to datacoral.

var e = emitter(
  'events.teamname.datacoral.io/events', // Collector endpoint
  '1js9q5Gqmk2VDv2omx2WI3yUGV0K7b464fWUJXDX', // api key
  'dev', // datacoral environment
  1, // Only send events once n are buffered. Defaults to 1 for GET requests and 10 for POST requests.
  function (error, response, body) { // Callback called for each request
    if (error) {
      console.log("Request to apigateway Collector failed!", response);
    }
  }
);

// Substitute appropriate value for appID.
var t = tracker([e], 'myTracker', 'appID', true);

// You can set the user ID to any string:

var datajson = {
  data: {
    price: 20
  }
};

var experiment_context = {
  name: "experiment",
  data: {
    key1: 'value1',
    key2: 'value2',
  }
};

var custom_context = {
    name: "custom",
    data: {
        pageType: 'test',
        lastUpdated: new Date(2014,1,26)
    }
};

var contexts = [experiment_context, custom_context];

t.trackUnstructEvent(datajson, contexts);
