Example use of Neon serverless driver on Vercel Edge Functions with raw SQL

neon-vercel-rawsql

This repo demonstrates using raw SQL with Neon's serverless driver on Vercel Edge Functions.

We implement a simple app that generates a JSON listing of the user's nearest 10 UNESCO World Heritage sites via IP geolocation (data copyright © 1992 – 2022 UNESCO/World Heritage Centre).
