Building

<<<<<<< HEAD

Download the latest Google's Closure Compiler and unzip it to the vendor directory.

=======

634e89511cc3dab16de8b4ac6e5cc68417a462ca Run rake build to build both the development and production JavaScript.

Requirements:

• Ruby. We recommend using Ruby 2.0. View the installation instructions.
• Google's Closure Compiler. Download the latest version, unzip, and place compiler.jar into the vendor directory.

All builds are placed in the build/ directory. Both development and production builds first assemble all JavaScript files in the src/ directory in the order defined in manifest.json. All JavaScript files are concatenated and compiled with Google's Closure Compiler. All errors and warnings will be printed to the console.

Usage

Start by creating a Blue Button document object by passing CCDA or VA C32 XML string to BlueButton:

var bb = BlueButton(xml);

The Blue Button document object, bb in this example, now exposes all patient data through a simple and consistent interface.

Sections

The health record sections are available using these public methods – JavaScript objects representing the patient data is returned from each:

// Returns the patient's personal information and demographics
bb.demographics();

// Returns the patient's allergies and alerts
bb.allergies();

// Returns the patient's encounters
bb.encounters();

// Returns a list of the patient's immunizations
bb.immunizations();

// Returns a list of the patient's laboratory results, organized by panel
bb.labs();

// Returns a list of the patient's medications
bb.medications();

// Returns the patient's problem list
bb.problems();

// Returns a list of the patient's procedures
bb.procedures();

// Returns a list of the patient's vital readings, grouped by date
bb.vitals();

Document Metadata

Information about the document itself can be accessed by using the document method:

// Returns an object containing information about the CCD document
bb.document();
