A modern runtime for JavaScript and TypeScript.

This adds support for peer dependencies in npm packages. 1. If not found higher in the tree (ancestor and ancestor siblings), peer dependencies are resolved like a dependency similar to npm 7. 2. Optional peer dependencies are only resolved if found higher in the tree. 3. This creates "copy packages" or duplicates of a package when a package has different resolution due to peer dependency resolution—see https://pnpm.io/how-peers-are-resolved. Unlike pnpm though, duplicates of packages will have `_1`, `_2`, etc. added to the end of the package version in the directory in order to minimize the chance of hitting the max file path limit on Windows. This is done for both the local "node_modules" directory and also the global npm cache. The files are hard linked in this case to reduce hard drive space. This is a first pass and the code is definitely more inefficient than it could be. Closes #15823 |

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.
- Set of reviewed standard modules that are guaranteed to work with Deno.
Install
Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):
brew install deno

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:
const listener = Deno.listen({ port: 8000 });
console.log("http://localhost:8000/");
for await (const conn of listener) {
serve(conn);
}
async function serve(conn: Deno.Conn) {
for await (const { respondWith } of Deno.serveHttp(conn)) {
respondWith(new Response("Hello world"));
}
}
You can find a deeper introduction, examples, and environment setup guides in the manual.
The complete API reference is available at the runtime documentation.
