Sanic implement shell like flask shell

Sanic how to implement functions like the flask shell . Convenient debugging

You mean a REPL preloaded with an app instance? This does not exist. Feel free to raise it as a feature request on our GitHub though.

I played around with the idea a little. This might be a nice addition.

How did you do it?
Has it been implemented?

No, but I might try to get it into the next release
