This is a Phoenix application that exposes the data from the New York Times Coronavirus (Covid-19) Data in the United States data set. This is βData from The New York Times, based on reports from state and local health agencies.β For more information, see their tracking page.
This is not my data. I do not work for The New York Times. I do not have any control over the data itself, nor can I vouch for its accuracy. If you have any questions or concerns with the data please see the contact info in their GitHub repository.
This project is currently live on Heroku, with the following endpoints available (more to follow):
- https://still-sea-82556.herokuapp.com/gql - GraphQL playground: simple queries for state, county and US data
- https://still-sea-82556.herokuapp.com/api/bay_area - all data for SF Bay Area counties
- https://still-sea-82556.herokuapp.com/api/states - see all state level data
- https://still-sea-82556.herokuapp.com/api/counties - see all county level data
- https://still-sea-82556.herokuapp.com/api/state/state_name - see all data for the supplied state, i.e. California. State name matching is case insensitive but you must escape spaces in states that have multiple words, i.e. West%20Virginia
- https://still-sea-82556.herokuapp.com/api/state/state_name/counties/county_name - see all data for the supplied state and county. state and county names are case insensitive and spaces must be escaped.
- https://still-sea-82556.herokuapp.com/api/fips/two_or_five_digit_code - look up states or counties by their Federal Information Processing Standards (FIPS), i.e. Alameda County.
- https://still-sea-82556.herokuapp.com/api/missing_fips - some records in the county data are missing fips. this endpoint displays them all.
- https://still-sea-82556.herokuapp.com/api/us - all us data.
- more to come ...
This is a hobby project and is a work in progress, therefore it may be broken or incomplete at times. If you happen to find this useful or have any suggestions or problems, please let me know, file an issue, contribute, etc.
This is a Phoenix project written in Elixir. It uses Absinthe for GraphQL.
The data sets are two CSV files. They are pulled via HTTP hourly, parsed and loaded into a Postgres database. The data model is simple and mirrors that of each data set. The two sets are completely independent. The HTTP ETag is respected so that file are only pulled and parsed if they've changed since the last pull (or last app tartup since the ETag data is stored in memory). As of today, it looks like the files are updated daily, sometimes several times to fix incorrect data, so an hourly pull should keep this application's data fresh.
Because each data point represents a single day's numbers (Covid19 cases and deaths per day per state or county), the data is continually growing and periodically adjusted to reflect new information. To model this on the database side, rows have a unique constraint on the date and state (and county for county data) so that revised data is fixed rather than added.
- the CSV parsing pipelines could be more
dry
, lots of repeated code - docs in the code
- tests
- configify the CSV urls and make local endpoints to serve for testing and development
To start your Phoenix server:
- Install dependencies with
mix deps.get
- Create and migrate your database with
mix ecto.setup
- Install Node.js dependencies with
cd assets && npm install
- Start Phoenix endpoint with
mix phx.server
Now you can visit localhost:4000
from your browser.
