[z2d]Blockstack Tutorial:To-do list

The hello-world tutorial is now redirected to the to-do list app.
Is the shirt offer over or not?
Also,before publishing[app.co], do we need to change the code in any way?
Lastly upon running npm install, the code pulled 1124 modules and 247MB of dependencies
For a to-do list, this seems a bit much .Also after decrypting the to-do list by make public, we get the following error
Unhandled Rejection (PreconditionFailedError): Error when uploading to Gaia hub.
