Today's quiz is to deploy a server-rendered hello world app (python3 -mhttp.server fine for these purposes, though I used Go below), publically visible, on your cloud of choice. On your marks, get set, GO!

$ ssh exe.dev new --name mr-rogers
$ ssh exe.dev share set-public mr-rogers
$ ssh mr-rogers.exe.xyz
# on that machine:
$ cat > main.go
package main

import (
        "fmt"
        "net/http"
)

func main() {
        http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
                fmt.Fprintln(w, "hello world")
        })
        http.ListenAndServe(":8000", nil)
}
^D
$ go run main.go  # maybe in a tmux

# back on your laptop, open https://mr-rogers.exe.xyz/

At exe.dev, our goal is to make sharing a web app that you built as easy as forwarding an e-mail. You saw the command-line approach above; there's an equivalent web-based flow as well.

If you don't want to share with the whole world, but only some friends, the share command also takes e-mail addresses, and your users can log into your site.

If you use exe.dev on a team, the sharing hierarchy is richer in that you can also share SSH access to your VM with a team member. The full hierarchy of sharing is:
