Release notes

The Neon serverless driver was verified to work with Deno. Where you would install another PostgreSQL driver, run npm install @neondatabase/serverless instead, and then import the Neon serverless driver:

import { Pool } from 'npm:@neondatabase/serverless';

Released a new version of the Neon serverless driver (v0.2.6), which allows you to query data from Cloudflare Workers, Vercel Edge Functions, and other environments that support WebSockets. The updated driver offers:

• Automatic import of the ws (WebSocket library) package if required, which makes the driver easier to use on StackBlitz and with Zapatos, for example.
• More helpful error messages when connection details are not provided. For example, a more informative error message is reported if you forget to set an environment variable for the database connection or forget to include a password in your database connection string.

Added three new example application repositories to help you get started with the Neon serverless driver on Vercel Edge Functions. The example application generates a JSON listing of the 10 nearest UNESCO World Heritage sites using IP geolocation (data copyright © 1992 – 2022 UNESCO/World Heritage Centre).

• The neondatabase/neon-vercel-rawsql example demonstrates using raw SQL with Neon's serverless driver on Vercel Edge Functions.
• The neondatabase/neon-vercel-zapatos example demonstrates using Zapatos with Neon's serverless driver on Vercel Edge Functions. Zapatos offers zero-abstraction Postgres for TypeScript.
• The neondatabase/neon-vercel-kysely example demonstrates using kysely and kysely-codegen with Neon's serverless driver on Vercel Edge Functions. Kysely is a type-safe and autocompletion-friendly typescript SQL query builder. kysely-codegen generates Kysely type definitions from your database.

The UNESCO World Heritage sites example is also available for the Neon serverless driver on Cloudflare Workers. See neondatabase/serverless-cfworker-demo.
