paperboi

always 'bout that paper, boy

Using NewsAPI, paperboi fetches very specific COVID-19 related news article and returns them neatly organized by state or U.S. territory with the title of the article, a link to it, and the publication date.

Results are cached to avoid reaching the daily 500 request limit from NewsAPI. The entire constructed hash body of each state-specific query is digested with Digest::SHA1.base64digest to create a fairly compact but unique and repeatable key for Redis, then a request is made to NewsAPI, and only relevant news article data is serialized into a JSON object containing: title, content, url, publishedAt. There is no cache eviction strategy but the cache will automatically expire after the end of the EDT/EST timezone day since all NewsAPI queries are scoped a 3-day window starting today and going back 3 days.
