Missing basic event listener on request - response

[itsfuad]

Nodejs has,

req.on("data", (data) => console.log(`on data: ${data.length}`));
req.on("close", () => console.log("req closed"));
req.on("aborted", () => console.log("req aborted"));
req.on("error", (err) => console.log("req error", err));

These events are very useful when server is doing a heavy task for the user. But it continues to do the work even the client is disconnected.

This is a serious issue in Deno. It doesn't have any way to know these things.

For response, node has,

res.on('end', () => console.log('Streaming is done'));

This way we know that the server has done the file or any kind of data streaming. Which is also missing in Deno.

It has a lot own methods. So why not implement those what developers need?
