What is Deno?

Deno is a secure-by-default runtime for JavaScript and TypeScript with built-in tooling, Web-standard APIs, and native TypeScript support — created by Node.js's original author.

Smart Stack indexes the official Deno documentation and keeps it current, so you can search it directly or ask questions in plain language. Because answers are grounded in the real pages — not a model's training data — you get correct, version-aware APIs instead of plausible-looking guesses.

Deno — FAQ

What is the latest version of Deno?

The latest version of Deno indexed in Smart Stack is 2.1.0. Smart Stack re-checks sources on a schedule, so answers stay current with releases rather than relying on a model's training cutoff.

Where can I find the official Deno documentation?

The official Deno documentation lives at https://docs.deno.com. Smart Stack indexes it so you can search across it — and the rest of your stack — and get AI answers grounded in those exact pages.

Can I search Deno docs together with the rest of my stack?

Yes. That's the core idea behind Smart Stack: add Deno to your stack alongside your other tools, and the AI answers questions using the official docs for everything you selected at once — no tab-switching.

Does Smart Stack hallucinate Deno APIs?

Smart Stack uses retrieval-augmented generation: it pulls relevant sections from the official Deno documentation and grounds the answer in them, which sharply reduces the made-up function signatures you get from ungrounded models.

What works well with Deno?

Deno is commonly used with tools in the languages space and adjacent layers of the stack. Add them together in Smart Stack to get integration-aware answers that understand how they fit.
