dao

The Cloudlet Platforms dao component persists data and retrieves it from the datastore. At the moment it is just a demonstrator so it destroys and recreates the database each time it is restarted.

Getting Started

Install the module with: npm install git+ssh://git@gitlab.openi-ict.eu:dao.git

You will need to install the following through macports or aptitude.

sudo port install JsCoverage
sudo port install phantomjs

or

sudo apt-get install JsCoverage
sudo apt-get install phantomjs

To build the project enter the following commands. Note: npm install is only required the first time the module is built or if a new dependency is added. There are a number of grunt tasks that can be executed including: test, cover, default and jenkins. The jenkins task is executed on the build server, if it doesn't pass then the build will fail.

git clone git@gitlab.openi-ict.eu:dao.git
cd dao
npm install
grunt jenkins

To start the component enter:

node lib/local-runner.js
