GPII Universal

Cross platform, core components of the GPII personalization infrastructure. This repository should not be used directly,
but in conjunction with one of the top-level GPII architecture-specific repositories. Documentation for this project is
housed beneath .


In production, this repository should be installed using one of the top-level GPII architecture-specific repositories -

For development purposes this repository could be cloned directly.

Quick Start

To verify the basic installation of GPII universal, you can start the core framework with

npm start

If all is well, you will see a message like

01:51:07.289:  Kettle Server 2us8uqry-22 is listening on port 8081

Note that this installation will not include any OS-specific features, but can be used to verify system function with
basic preference sets which only start solutions which require filesystem-based configuration (XML, JSON or .INI files).

Recovering From System Corruption Using the Journal

Either when operating the live GPII system or running test cases, you may end up corrupting your desktop settings in the
case there is a system crash. In this case, you can navigate to


to browse a set of journal recovery snapshots. Clicking on the first link on this page will restore your system
to the state it was in prior to the most recent GPII login.


There are currently 3 different sets of tests:

  • the ones that run in the browser
  • the ones run in node.js
  • production tests, running in node.js but having external requirements

Running browser tests:

open {universal}/tests/web/html/all-tests.html in your preferred browser

Running node-based tests

From the root of the universal folder, run the following command:

npm test

Running tests using a VM

A VM can be automatically created using tools provided by the Prosperity4All Quality Infrastructure. Please ensure the requirements have been met. The vagrant up command can then be used to provision a new VM.

Within the VM, the application will be installed in the directory specified by the nodejs_app_install_dir variable, which is defined in the provisioning/vagrant-vars.yml configuration file in this repository. By default it is set to "/home/vagrant/sync/node_modules/universal".

Following the provisioning phase, tests can be run in the VM directly from the host system, without the need to log into the VM or interact with its console.

From your project's top-level directory (where the Vagrantfile and Gruntfile.js files reside), run:

  • node-based tests: grunt node-tests
  • browser-based tests: grunt browser-tests
  • production tests: grunt node-production-tests

The grunt tests command will run the browser and Node based tests.

These Grunt tasks will run the correct Vagrant commands to connect to the VM and run the tests within the isolated environment. You can also run vagrant ssh to connect to the VM (or open the VirtualBox console and interface with the desktop environment) and run the tests manually if you wish.


To use any of the gpii components or functionality in node.js, use the
following statements to get access to fluid and/or gpii objects.

var fluid = require("universal"),
    gpii = fluid.registerNamespace("gpii");
// Now you will have access to both fluid and gpii namespaces.

Running node-based production tests

The purpose of these tests are to test production config setups of the system. This involves using the online preferences server when fetching preferences sets, so there are extended requirements for these tests.

These tests are a supplement to the all-tests.js (and hence not part of that test suite) and should be run separately when testing the system and having the below requirements available.


  • an internet connection
  • a preferences server running at containing at least the following (unmodified) NP set: MikelVargas

The tests are run using the following command:

node tests/ProductionConfigTests.js

Building Docker Images

The Dockerfile can be used to build a containerized version of GPII Universal, at this time primarily for use by downstream containers running components such the Preferences Server and Flow Manager in standalone cloud configuration.

The following command can be used to build an image locally as long as it is run relative to the repository's Dockerfile:

docker build --rm -t gpii/universal:$(git rev-parse --short HEAD) .

That will use the Git repository's current abbreviated commit hash as a Docker tag. If you would like to download the latest public Universal image you can use this command:

docker pull gpii/universal

Or use the following command to download a particular image identified using a Git commit hash:

docker pull gpii/universal:<first seven characters of a git commit hash>

Additional notes:

  • The Docker image is built within the container using the same Ansible role used to provision VMs, to simplify the management of different environments.
  • Universal is installed to /opt/gpii/node_modules/universal to allow the node-based test cases to resolve. Regarding the tests:
    • Currently, the node-based tests are always run when this container is built. If you would like to turn this off for local debugging or faster building, remove the npm test item in the nodejs_app_commands list in provisioning/docker-vars.yml
