Node VCAP Services Parser

A parser for VCAP_SERVICES environmental variable used by CloudFoundry applications. It can return all of the services bound to an application or a subset of them.

Usage

// Import the module
var vcapServices = require('vcap-services-parser');

// Create a parser with plugins for supported Bluemix services
var parser = new vcapServices.Parser(vcapServices.bluemix);

// Resolve all services
var services = parser.resolveAll();
console.log(services.cloudant.host);

// Resolve a specific service
var speechToText = parser.resolve('speech-to-text');
console.log(speechToText.url);

// Resolve several services
var selectedServices = parser.resolve(['speech-to-text', 'cloudant']);
console.log(selectedServices['speech-to-text'].url);
console.log(selectedServices.cloudant.host);

Services

When multiple services are resolved an object is returned that maps from the service name to a description of the service. When a single service is resolved a description of the service is returned. Included in all service descriptions are the instance name, plan and service tags. Different services can have different properties.
