Neon has released its Serverless Driver 0.9.0 on Deno's JavaScript Registry (JSR), marking the introduction of a fast, Edge-compatible Postgres driver designed to optimize query latencies for V8-isolate runtimes such as Deno and Cloudflare Workers. This driver allows connections to databases via WebSocket instead of the traditional TCP, significantly reducing query latency times to sub-10 milliseconds. The JSR is an npm-like registry optimized for TypeScript and ECMAScript Modules, catering to new JavaScript runtimes like Cloudflare Workers and Bun. The serverless driver can be added to projects using the "deno add" command, and it supports integration across multiple JavaScript environments, including Deno, Bun, and Node. The Neon team encourages developers to try the driver, offering free trials and support through platforms like Discord, while also providing deployment options via Deno Deploy and GitHub integration.
