Both directories and files can be served by registering with static
app = Sanic(__name__)
# Serves files from the static folder to the URL /static
app.static('/static', './static')
# Serves the file /home/ubuntu/test.png when the URL /the_best.png
# is requested
app.static('/the_best.png', '/home/ubuntu/test.png')
app.run(host="0.0.0.0", port=8000)
