Ways to organize jade?

Question

Building projects

For organizing css, there is SMACSS - “scalable and modular architecture for CSS”,
but what is similar for jade?
For example, now I have the following structure:

- app
    |__  _common
    |     |__ layout
    |     |    |__ _header.jade
    |     |    |__ _footerjade
    |     |
    |     |__ main.jade
    |
    |___ index.jade

I don't think this structure is correct.

Answer 1

I have all mixins. There are modules that are like building blocks, and there are pages, this is the place where I assemble the page from them

Answer 2

It's not very clear what the question is. pug/jade has inheritance, parshials and mixins. What else is needed in order to make a scalable and modular architecture?
