GPII Universal

The package contains 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. Additional documentation is available on our wiki.


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

For development purposes this repository can also 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).

Environment Variables

Through the use of Kettle resolvers, some pre-defined configuration files offer the ability to read environment variables to change commonly used settings.

Preferences Server

The Preferences Server with the gpii.config.cloudBased.flowManager.production configuration uses the following variables:


GPII_PREFERENCES_DATASOURCE_URL=https://localhost:5984/%userToken \
NODE_ENV=gpii.config.cloudBased.flowManager.production \
npm start

Flow Manager

The Flow Manager with the gpii.config.cloudBased.flowManager.production configuration uses the following variables:


GPII_FLOWMANAGER_PREFERENCES_URL=http://localhost:9090/preferences/%userToken \
NODE_ENV=gpii.config.cloudBased.flowManager.production \
npm start

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:

  • Tests that run in the browser
  • Tests that run in node.js
  • Production tests, that run in node.js, but which interact with external services.

The npm test command will run the browser and Node based tests. Please note, the node tests may behave oddly if you have set the NODE_ENV variable.

Running browser tests:

You can run the browser tests in this package with a range of browsers using Testem, and the configuration file tests/testem.js, which will ensure that code coverage information is collected. From the root of the universal folder, run the following command:

npm run test:browser

Please note, when running the browser tests locally using this command, the tests will fail on some browsers (notably Firefox, Safari, and Opera) unless the browser has focus. You can manually click the browser when it launches to give it focus. You should not give another window focus until the tests complete. This is not a problem when running the browser tests in Vagrant (see below). It's also not a problem when running the tests in Chrome, which you can do using a command like:

npm run test:browser -- --launch Chrome

You can also run (and debug) the tests manually from the root of the repository using a command like:

node node_modules/testem/testem.js --file tests/testem.js

The required test fixtures and testem will start, and Testem will provide a URL you can open in a browser.

If you would like to debug individual tests or view the test summary in a browser without using Testem, you can:

  1. Host the working directory, for example, using a command like the following from the root of the repository: python -m SimpleHTTPServer 4103
  2. Open the "rollup" file tests/all-tests.html that runs all tests in a browser. Continuing the above example, you would load the URL http://localhost:4103/tests/web/html/all-tests.html.

Please note, when hosting the tests yourself, you may see multiple 404 errors related to the /testem.js and /coverage/client/coverageSender.js files which are provided by Testem and the gpii.testem harness respectively. These 404 errors will not cause any tests to fail and can be safely ignored.

Running node-based tests

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

npm run test:node

Please note, the node tests may behave oddly if you have set the NODE_ENV variable.

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 provisioning/vagrant-vars.yml configuration file in this repository. By default the installation directory 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 package.json files reside), run:

  • Node and browser tests: npm run test:vagrant
  • Node tests only: npm run test:vagrantNode
  • browser tests only: npm run test:vagrantBrowser
  • production tests: npm run test:vagrantProduction

The test:vagrantProduction target will use the script to spin up container-based GPII components inside the VM.

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("infusion"),
    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

Coverage Reporting

The preferred way to consistentely generate a code coverage report is to use Vagrant as described above. When you start a VM using vagrant up and run npm run test:vagrant, the full test suite will run in the VM, and a coverage report will be saved to the reports directory. You can also run the npm test command on your local machine, but you will need to ensure that browsers receive focus when they are launched (see above).

The npm test command has two additional associated scripts. The pretest script runs before the command defined for the test script. The posttest script runs after. In our case we use a pretest script to clean up previous coverage data before we run the tests, and a posttest script to compile the actual report. You should not need to run the pretest scripts manually before running either the node or browser tests, or to run the posttest scripts afterward.

Docker Containers

The provided Dockerfile can be used to run GPII Universal directly.

Build image

To build a Docker image simply run: docker build -t my-universal .

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>


npm i gpii-universal
