Interactive Maps & Graphs of Realtime COVID Data
Data is sourced from COVID ActNow which aggregates data from a variety of sources.
Service Workers are used to cache data from different APIs and are considered valid for up to 24 hours. By caching the data, we eliminate the need to continually hit the API servers and eliminate the need to keep large responses in memory.
Web Workers are used to load topography in the background and compute relative statistics for regions.
The topography is preprocessed so that minimal dependencies and processing is required at runtime in an effort to lower resource utilization. County shapes, county summaries and timeseries data are streamed in JSON format and processed on demand while streaming.
