Q:

Deno run is not working properly also drun

After created an index.ts and wrote a simple code for listening to port 3000 and printing hello world on the body, I'm also not able to run or get the output from deno's drun module. 
import { Application, Router } from "https://deno.land/x/denotrain@v0.5.0/mod.ts";

const app = new Application();

const router = new Router();

// Middleware 
app.use((ctx) => {

  ctx.cookies["user.session"] = "qwertz";
  ctx.cookies["a"] = "123";
  ctx.cookies["b"] = "456";
  delete ctx.cookies["user.session"];
  return;
});

router.get("/", (ctx) => {

  return new Promise((resolve) => resolve("This is the admin interface!"));  
});
router.get("/edit", async (ctx) => {
  return "This is an edit mode!";  
});

app.get("/", (ctx) => {

  return {"hello": "world"};
});

app.use("/admin", router);

app.get("/:id", (ctx) => {
  // Use url parameters
  return "Hello World with ID: " + ctx.req.params.id
});

  return ctx.req.body;
});

await app.run()

Development Environment:- Windows 10
The problem seems to be the address 0.0.0.0 is specific to mac only. Windows Doesn't use 0.0.0.0 address. 
After going to localhost:3000 / 127.0.0.1:3000.  I was able to get the output. I think maybe Windows redirects the 0.0.0.0 to localhost.  Anyway it solved my problem!
