joola.io is a distributed data processing and visualization framework. The framework is designed as an end-to-end solution for data analytics. The framework connects to your databases and using a JSON based mapping of dimensions and metrics, it exposes a RESTful API for querying the data. The Client SDK communicates with the engine to display, visualize and provide insight into the data. Developers can extend the framework in many ways, add data connectors, authentication plugins, visualizations and more.

To learn more about the framework architecture, see our documentation site.

The Engine

joola.io.engine provides the framework with its logic and data processes. It is the core of the framework. In a standard deployment, the engine will be used by joola.io.analytics to query data and visualize it using joola.io.sdk.

Caching is an important part of the framework, it allows joola.io to reply to queries in split seconds, this is also managed by the engine. Configuring the engine is not a difficulat task, but it requires understanding of the system, here's good place to start learning about configuration.

A good place to learn more about the Engine, is our docs.


$ npm install joola.io.engine


$ npm start
# point your browser to http://localhost:40004 
#  and you'll be answered by the REST API.
