ce-poc-algorithm

Welcome to the ce-poc-algorithm repository!

Quick Start

Make sure you have Node.js and Yarn installed on your local machine
Make sure you are running the CE API on your local machine.
Prepare the CE API with the initial data set by running all GraphQL queries in the Initial data section.
Update the .env files in the ./services/algorithm and ./services/frontend directories
Run the following command to start the containers $ yarn start

Algorithm container

The algorithm container starts a Node.js script which subscribes to changes in the CE API.

Frontend container

The frontend container is a Create React App application which visualises all ControlActions in the CE API and allows you to request new ControlActions with the required PropertyValues.

Visit the UI by navigating to http://localhost:3000.

Initial data

Run the following queries in your GraphiQL environment.
