Examples of how to run modules in the Deno standard library.

Deno also provides a list of audited standard modules that are reviewed by the core Deno team and are guaranteed to work with a specific Deno version. source

See denoland/deno repository for source code of Deno and standard lib.

These are hosted at deno.land/std.

Welcome

$ deno run https://deno.land/std/examples/welcome.ts

File server

Using std/http/file_server.ts:

$ deno run --allow-read --allow-net https://deno.land/std/http/file_server.ts

Or write a more complex one using http/server.ts:

  • index.ts 
      import { serve } from "https://deno.land/std@0.59.0/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" });
  }

Start the server.

$ deno run --allow-read --allow-net index.ts
