Parse and return service credentials from VCAP_SERVICES environment variable that Bluemix provides.

Installation

$ npm install vcap_services --save

Usage

var vcapServices = require('vcap_services');
var credentials = vcapServices.findCredentials({ service: 'personality_insights' });
console.log(credentials);

If VCAP_SERVICES is:

  "personality_insights": [{
      "credentials": {
        "password": "<password>",
        "url": "<url>",
        "username": "<username>"
      },
    "label": "personality_insights",
    "name": "personality-insights-service",
    "plan": "standard"
  }]
}

Output:

{
  "password": "<password>",
  "url": "<url>",
  "username": "<username>"
}
