About the application

• Stores the sampled data from sensors via /data endpoint for multiple sensors (sampled at each minute)
• Uses Mongo's timeseries collection optimized for IOT data collection
• It exposes /data endpoint for fetching sensor data based on sensorId and groupBy query params
• It asynchronously stores data in chunks when a large data file is uploaded via endpoints
• It uses node streams to process the data thus avoids memory overflows

Future Scope

• Push data to graph in realtime as chunks are processed by the server

Steps to Run via terminal

• Open two terminals one inside /client and one inside '/server'
• run npm install inside both the terminals for installing dependencies
• run npm start inside inside client folder
• update .env file inside server folder with appropriate mongo credentials
• ensure that mongo running
• run npm start for starting the server

Steps to Run via docker

• Run docker compose up --build --remove-orphans to setup the cluster and open localhost:3000 once done
