Consider reorganize the project structure for Heroku compatibility?

I'm trying to deploy it on Heroku (https://github.com/southwolf/midori-todo-example),
but Heroku won't automatically add nodejs build pack if no package.json in project root.
I have to run heroku buildpacks:add --index 1 heroku/nodejs.

Maybe it's better to reorganize the project structure, making it more friendly to users.

Sounds reasonable. I should make it easier to deploy on Heroku as an example project.
