A hackathon project for New Relic FutureHack 2022.
This endpoint accepts a query string containing units, lat, and lon, and returns the weather for that location.
To get the weather, it executes a call to OpenWeatherMap's API. This call can take anywhere from 100ms to 500ms.
This application adds a cache layer to that request. Cached responses return in under 50ms- a significant improvement over the origin API request. This results in a major user experience improvement.
We've instrumented HarperDB using the Node.js New Relic agent. The result is the ability to see response times in the New Relic dashboard, and set a cache timeout value that strikes a balance between timeliness and response time.
