Morrigan

Note: Morrigan is an experimental project. It is not feature complete or audited for security.

The goal of Morrigan is to create a platform-independent, scalable and extendable solution for device administration and management.

Platform independence: Both the server and the client are designed to run in Node.js, and should not rely on OS specific functionality.

Fault tolerance: The server is intended to run as a peer in a cluster. Authentication and client state should remain valid across all server instances, so if a server goes down you just need to reconnect to another server and carry on where you left off.

Scalability: If you need more servers you can simply reuse existing settings when spinning up a new server/instance.

Extendability: The capabilities of the server and client sides of the system can be extended using components and providers.

Installation

Via NPM:

npm install morrigan.server

Configuration

The Morrigan constructor expects a settings object, with at least the following keys:

• database: An object with connection details for the MongoDB instance to use.
• components: Object specifying the components to use and their settings.

See server.settings.sample.js for more information.

Components & Providers

Morrigan uses Components to define server functionality, and each component is then expetcted to load providers that further define it's functionality.

Components

Components are modules that exports a setup method:

setup(name, specification, router, environment)

Which should accept the following arguments:

• name: The name used to register the component in the component specifications (see server.settings)
• specification: The component specification. This can be used to quickly access component-specific settings.
• router: Express router to define routes on if necessary. This router will be mounted under /${name}/ on the server.
• environment: The server environment under which the component should run. Contains the following keys:
  • db: The MongoDB database used by the server (using the 'mongodb' module's Db object, see https://mongodb.github.io/node-mongodb-native/3.7/api/Db.html).
  • info: Server info object.
  • log: Logging function (log(message, level)).
  • settings: The full settings object as passed to the server constructor function.

What Morrigan is NOT

The morrigan server does not provide a visual front-end, only a REST API and WebSocket message API.
