Blue Button Web Server

Build Status Coverage Status

This server serves as a data provider for sharing Medicare claims data with third parties. The server connects to MyMedicare.gov for authentication, and uses OAuth2 to confirm permission grants to external app developers. The data itself comes from a back end FHIR server (https://github.com/CMSgov/bluebutton-data-server), which in turn pulls data from the CMS Chronic Conditions Warehouse (https://www.ccwdata.org)

For more information on how to connect to the API implemented here, check out our developer documentation at https://cmsgov.github.io/bluebutton-developer-help/. Our most recent deployment is at https://sandbox.bluebutton.cms.gov, and you can also check out our Google Group at https://groups.google.com/forum/#!forum/developer-group-for-cms-blue-button-api for more details.

The information below outlines setting up the server for development or your own environment. For general information on deploying Django see https://docs.djangoproject.com/en/1.11/howto/deployment/.

Setup

These instructions provide a quick start for developers new to the project. Follow these steps on the command line.

# prepare your repository folder
git clone https://github.com/CMSGov/bluebutton-web-server.git
cd bluebutton-web-server

# create the virtualenv
python3 -m venv venv

# Install any prerequisites  (C headers, etc. This is OS specific)
# Ubuntu example
sudo apt-get install python3-dev libxml2-dev libxslt1-dev


# install the requirements
pip install --upgrade pip==9.0.1
pip install pip-tools
pip install -r requirements/requirements.txt

# prepare Django settings
cp hhs_oauth_server/settings/local_sample.txt hhs_oauth_server/settings/local.py

Note that most settings can be overridden by environment variables. See custom environment variables section below. Please ensure to create and use your own keys and secrets. See https://docs.djangoproject.com/en/1.11/topics/settings/ for more information. Continue the installation by issuing the following commands:

python manage.py migrate
python manage.py loaddata apps/accounts/fixtures/scopes_and_groups.json
python manage.py createsuperuser
python manage.py create_admin_groups
python manage.py create_blue_button_scopes
python manage.py setup_bluebutton
python manage.py create_test_user_and_application

The next step is optional: If your backend HAPI FHIR server is configured to require x509 certificates to access it then you need to obtain that keypair and place those files in certificate folder called cerstore.

mkdir ../certstore
(copy both x509 files, in PEM format, inside certstore)

If your backend FHIR server does not require certificate-based authorization then the previous step can be omitted.

Making calls to a back-end FHIR server requires that you set a series of variables before running tests or the server itself.

#Run the development server
python manage.py runserver

Note you can find the path to your Python3 binary by typing which python3.

docker-compose setup

Instructions for running the development environment via docker-compose can be found here

How to View the CSS/Styles Locally

To keep our CSS organized and consolidated across our applications, we use a dedicated Blue Button CSS Repo.

In order to be able to see the styles locally for this project, you'll just need to clone the Blue Button CSS Repo at the root of this project.

From within bluebutton-web-server, run the following commands (Bash):

git clone git@github.com:CMSgov/bluebutton-css.git

That sould be all you need to get the styles working. The instructions below will tell you how to work with or update the SCSS.

To get started making changes to the styles:

cd bluebutton-css

You'll need to make sure you have NodeJS installed. Click here to find out more about NodeJS. Once you have NodeJs installed, run:

npm i

Finally, make sure you have Gulp 4.0 installed:

npm i gulp@4

To export the CSS once, run:

gulp

To watch the SCSS files for changes, run:

gulp watch

Running Tests

Run the following:

python runtests.py

You can run individual applications tests as well. See https://docs.djangoproject.com/en/1.11/topics/testing/overview/#running-tests for more information.
