9.3 Creating a Library
We've seen the directory structure above for a library project. We're defining a "library" project as one that doesn't start up any services as part of its basic operations. Instead, it provides code that other projects make use of.
In particular, in a library project, you do not need to define
mod in your
ebin/libname.app file. Similarly, in your
src directory, you do not need
to create application nor supervisor files.
We're making a rather arbitrary distinction here (between "library" projects and "service" projects, and one with undoubtedly many blurry lines. Regardless, it may be instructive or useful as a guideline.
