It's worth noting that there are a couple of edge cases we're not dealing with properly at the moment. If we send malformed `json`, or if a request is made with a method that the view doesn't handle, then we'll end up with a 500 "server error" response. Still, this'll do for now.

Quit the server with CONTROL-C.

In another terminal window, we can test the server.

We can get a list of all of the snippets (we only have one at the moment)

curl http://127.0.0.1:8000/snippets/

{"id": 1, "title": "", "code": "print \"hello, world\"\n", "linenos": false, "language": "python", "style": "friendly"}
