About project structure

Hello! I’m starting to build a medium-sized web application and I like to use ionic for that (I love Ionic IU and its performance). I try the following project structure (it is just an example). What do you think?

Why not put the providers at src level?

(Folder services)

I thought, but in similar applications, without ionic, I have at least 70 or more providers. That’s why I think it’s better to separate them.
For example:

    |-- services
    |-- services
