App.listen()#

With this function you start the server to listen for http requests. By default, the server runs on port :8000.

You can also run the server by selecting the one you want:

app.listen("http://localhost:8080") 
// or app.listen(":8080")
// or with custom listener
app.listen(null, Deno.listen({ port: 8080 }))

Errors that haven't been caught elsewhere get in here
