space-app's Introduction

Space App

Responsible for receiving sensor temperature data (fahrenheit) in space (via http request).

Persists data - and keeps track of data that has not been synced to a consumer on Earth.

Converts temperature data from fahrenheit to celsius; then serializes un-consumed data from space application to earth an Earth consumer.

Data is sent to earth as it is generated.

A cron job runs in the background every minute (can be adjusted).

The cron job is responsible for checking if any unsynced data exists - if such data exists a sync is attempted.

The cron job is responsible for retrying to sync unsynced data that may not have reached earth (as the application faces network blackouts - rogers or space)

Usage/Examples

  # mock sensor data with http request:
  POST http://localhost:3000/temperatures

  JSON request body
  {
    "temperature": $temperature
  }

  # app should push temperature data onto a redis list - then attempt to sync to consumer.
  # if successful response from consumer - pop synced temperature data from redis list
