Green Ecolution Backend 🌿

Smart irrigation is essential to saving water, reducing staff workload, and cutting costs. This project provides the backend for Green Ecolution — a digital system to manage urban greenery efficiently.

👉 For the frontend implementation, visit the Green Ecolution Frontend.

The backend acts as the interface between the website and the database, managing data about:

• 🌳 Trees
• 🌿 Tree clusters
• 📡 Sensors
• 🗺️ Watering plans
• 🚛 Vehicles
• 👤 Users

In the current setup, sensors are connected to a microcontroller with an LoRaWAN modules. Sensor data is transmitted via LoRaWAN to an MQTT gateway, then forwarded to the server for processing.

Developed in collaboration with TBZ Flensburg, this software is designed to be adaptable for other cities. It originated as a research project within the Applied Computer Science Master's program at the University of Applied Sciences Flensburg.

Quick Start Guide 🚀

To quickly run the application locally:

1. Clone this repository
2. Copy the env.example to .env
3. Build and launch the application containers

make run/docker

make will download a pbf file of the open street map geographical tileset from Germany Schleswig-Holstein and place it in a directory where vahalla can access it via docker. If you don't want to download this part or want to load a different location into valhalla, you can download it yourself and place the file in .docker/infra/valhalla/custom_files/<file-osm.pbf>. After that you can start the docker services with the backend using this command:

docker compose -f compose.yaml -f compose.app.yaml up -d --build

By default, all services such as auth, routing and s3 are enabled and running with docker, except mqtt. This service is currently disabled by default and must be configured manually.

👉 Once the service is up and running, the backend is available at: http://localhost:3000

The other services can be accessed via the following URLs:

Technologies Used ⚙️

• Go (Golang) as the main language
• env for environment configuration
• godotenv for .env file handling
• Fiber as the web framework
• Testify for unit testing
