Neon has released Serverless Driver 0.9.0 for Deno's JavaScript Registry (JSR). JSR is designed to work with TypeScript, ECMAScript Modules, and new JavaScript runtimes like Cloudflare Workers and Bun. The serverless driver allows V8-isolate runtimes such as Deno and Cloudflare Workers to connect to the database via protocols other than TCP, offering faster query latencies. It can be added to projects using the "deno add" command and is compatible with multiple JavaScript runtimes including Deno, Cloudflare, Bun, and Node.
