20 Minutes to Build a Serverless COVID-19 GraphQL API

on YouTube ↗25m

" summary

Builds a public GraphQL API from Johns Hopkins CSVs in 20 minutes by transforming five time‑series files into tidy MongoDB collections (global, us_only, country_summary) using a Python import/cleanup pipeline, generating a JSON schema from a 500‑document sample, and deploying a GraphQL endpoint on MongoDB Atlas and Realm with anonymous and email/password auth. The live system supports hourly updates, geospatial points, daily deltas computed via aggregation pipelines, and a downloadable schema and resolver hooks — and it runs in the free tier.
