System Architecture

Tombolo’s architecture integrates a React frontend, Node.js backend, MySQL and and external services like HPCC, with notification support via a mail server. The diagram below illustrates the system’s components and their interactions.

1. Users access Tombolo through a React app served by Nginx.
2. The frontend communicates with a Node.js backend via API calls.
3. The backend uses Sequelize to interact with a MySQL database.
4. The backend connects to an HPCC server via the HPCC JS comms library.
5. Notifications are sent via an external mail server.
6. All services (React, Node.js, MySQL) are packaged as Docker containers, orchestrated with a docker-compose.yml file located in Tombolo/Tombolo.
