A modern runtime for JavaScript and TypeScript.

This tweaks the signature of `request_builder_hook` in order to support fallible hooks. The rationale for this is mostly on two sides: * it allows a hook to inspect and possibly drop an outgoing request (e.g. for policying purposes), bubbling up a detailed error message to the user. * it wires into newer `reqwest` API which allows to split and then reassemble a `RequestBuilder`, although only in a fallible way (https://github.com/seanmonstar/reqwest/pull/1770) |

- 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.

Shell (Mac, Linux):
curl -fsSL https://deno.land/install.sh | sh
PowerShell (Windows):
irm https://deno.land/install.ps1 | iex
Homebrew (Mac):

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.
