enviro-check

To Do:

• Sort out who can create accounts
• Add Tests
• Add Docs and comments
• load Json file into db on request, should check for admin only
• Sort db migrations
• Use Swagger to generate docs
• Dockerise App

Enviro-Check is a webserver application that accepts JSON lat and long values to return live weather information from the closest weather station.

GO:

• built on Go (Golang) version 1.17

Uses:

• [OpenWeatherMap] for weather information (openweathermap.org)

Requires:

• Redis for as Key Value store
• Postgres for database non volatile memory storage

Directions:

1. Create an acount and generate a valid OpenWeatherMap API token (https://home.openweathermap.org/users/sign_up)
2. Clone the repository
3. Update the values in .env-example and update name to .env
4. Ensure Redis is running with '$ redis-server'
5. Run with './run.sh'

Usage Example:

Send a 'Post' Request on 'localhost:5000/' as JSON, { "lat": -33.86, "long": 151.20 }

Application Returns: { "name": "Ostrovnoy", "sys": { "country": "RU", "sunrise": 1629854503, "sunset": 1629912408 }, "coord": { "lat": 68.0531, "long": 0 }, "weather": [ { "main": "Clouds", "description": "overcast clouds" } ], "main": { "temp": 282.16, "temp_min": 282.16, "temp_max": 282.16, "pressure": 1022, "humidity": 58 }, "visiblity": 0, "clouds": { "all": 87 }, "wind": { "speed": 4.79, "deg": 75, "gust": 3.79 }, "cod": 200 }

Performance:

• Calculates and returns weather information as JSON on average 1.2 seconds with 50up/20down connection speeds

Roadmap:

• Add authentication via JWT
• Use db for authentication
• Improve JSON error responses
• Run as Docker for cloud deploy
• Add stream via gRPC

Minor ToDo's:

• Create Redis client as application variable (remove duplication of code)

Other Ideas:

• add density indicators (traffic? 4G coverage? housing data?)
• ArcGIS urban density calculators
• add low altitude airspace information (flight paths? ADS-B information)
