denort is an optimization to "deno compile" to produce slightly smaller
output. It's a decent idea, but causes a lot of negative side-effects:
- Deno's link time is a source of constant agony both locally and in CI,
denort doubles link time.
- The release process is a long and arduous undertaking with many manual
steps. denort necessitates an additional manual zip + upload from M1
apple computers.
- The "deno compile" interface is complicated with the "--lite" option.
This is confusing for uses ("why wouldn't you want lite?").
The benefits of this feature do not outweigh the negatives. We must find
a different approach to optimizing "deno compile" output.

Deno
Deno is a simple, modern and secure runtime for JavaScript and TypeScript that uses V8 and is built in Rust.
Features
- Secure by default. No file, network, or environment access, unless explicitly enabled.
- Supports TypeScript out of the box.
- Ships only a single executable file.
- Built-in utilities like a dependency inspector (deno info) and a code formatter (deno fmt).
- Set of reviewed standard modules that are guaranteed to work with Deno.
Install

See deno_install and releases for other options.
Getting Started
Try running a simple program:
deno run https://deno.land/std/examples/welcome.ts
Or a more complex one:
import { serve } from "https://deno.land/std/http/server.ts";
const s = serve({ port: 8000 });
console.log("http://localhost:8000/");
for await (const req of s) {
req.respond({ body: "Hello World\n" });
}
You can find a deeper introduction, examples, and environment setup guides in the manual.
The complete API reference is available at the runtime documentation.
