Diastema web app

Description

The web application of the project, utilizing a basic Node.js [1] express [2] API for all the different routes and functionalities. These include:

• An interactive Dashboard
• The Process Modelling component
• Dataset management interface
• A Custom Function Modelling component
• Application monitoring
• Adaptive data visualization

How to use

Prerequisites

• Node.js
• Docker [3]
• Orchestrator Service

How to run

Create a .env file containing the following:

PORT=5400

MONGO_URL=mongodb://mongo/

MINIO_URL=host.docker.internal
MINIO_ACCESS_KEY=diastema
MINIO_SECRET_KEY=diastema

ORCHESTRATOR_URL=http://83.212.238.166:50001/analysis
ORCHESTRATOR_INGESTION_URL=http://83.212.238.166:50001/ingestion

NORMALIZATION_URL=http://normalization:5000/normalize
VALIDATION_URL=http://validation:5001/validation

NODE_ENV=development

Run the following commands to install node modules and start the script for development / testing:

npm install
npm run docker:dev

The development script will also start some required services as containers:

• Function Normalization Service
• Graph Validation Service
• A dummy Data Verifier Service
• A MongoDB [4] database
• And a MinIO [5] object storage

You can now visit http://localhost:5400 where the application will be running.

Additional scripts

Some additional npm scripts have been created to execute complex Docker commands, such as:

• npm run docker:downdev will stop and delete running containers in development mode
• npm run docker:build will build the image again and then start the development containers
• npm run docker:prod will start just the application container. Requires proper environment variables configuration
• npm run docker:downprod will stop and delete running containers in production mode
