Hi,

I’m developing a project that consists of multiple packages and some code that uses those packages.  
The packages will not be published in the Julia registry as it is a purely personal / learning project.

Is there some recommended way how to set this up in the filesystem using a single git repository?

For example, would this structure work:

```julia
/myproject
|- libA/
| |- src/
| | |- libA.jl
| |- Project.toml
| |- Manifest.toml
|- libB/
| |- src/
| | |- libB.jl
| |- Project.toml
| |- Manifest.toml
|- src/
| |- main.jl
|- Project.toml
|- Manifest.toml

```

where `libA` and `libB` are imported into `myproject` via `Pkg.develop()`? Or is it common to put `libA` and `libB` into a `deps/` or `libs/` folder within `myproject/`?

A `libs` directory might be more “conventional”. Some packages like Makie.jl have a layout as you suggest:

> **[GitHub - MakieOrg/Makie.jl: Interactive data visualizations and plotting in...](https://github.com/MakieOrg/Makie.jl)**
>
> Interactive data visualizations and plotting in Julia - GitHub - MakieOrg/Makie.jl: Interactive data visualizations and plotting in Julia
