Deno run is not working properly also drun - deno

Question

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!

Answer 2

I am on windows. I faced with the same problem. Then,
const app = new Application({hostname:"127.0.0.1"});
I created the app in typescript giving parameter hostname like above.
And run deno like this:
deno run --allow-net=127.0.0.1 index.ts
it worked.

Run your server with the following command:
drun watch --entryPoint=./server.ts --runtimeOptions=--allow-net
In any case most Deno tools for watching changes are still bugged, I recommend to use nodemon, with --exec flag
nodemon --exec deno run --allow-net server.ts
For convenience you can use nodemon.json with the following content:
{
"execMap": {
"js": "deno run --allow-net",
"ts": "deno run --allow-net"
},
"ext": "js,json,ts"
}
And now just use: nodemon server.ts

It seems that you have an error in your code snippet, with the last
return ctx.req.body;
});
If you fix that and use the last deno (v1.0.1) and drun(v1.1.0) versions it should works with the following command:
drun --entryPoint=index.ts --runtimeOptions=--allow-net
