MkApi Documentation

MkApi plugin for MkDocs generates API documentation for Python code. MkApi supports two styles of docstrings: Google and NumPy.

Features of MkApi are:

  • Type annotation: If you write your function such as def func(x: int) -> str:, you don't need write type(s) in Parameters, Returns, or Yields section again. You can overwrite the type annotation in the corresponding docstring.
  • Object type inspection: MkApi plugin creates class, dataclass, function, or generator prefix for each object.
  • Attribute inspection: If you write attributes with description as comment in module or class, Attributes section is automatically created.
  • Docstring inheritance: Docstring of a subclass can inherit parameters and attributes description from its superclasses.
  • Table of Contents: Table of contents are inserted into the documentation of each package, module, and class.
  • Page mode: Comprehensive API documentation for your project, in which objects are linked to each other by type annotation.
  • Bidirectional Link: Using the Page mode, bidirectional links are created between documentation and source code.


Install the plugin using pip:

pip install mkapi


Add the following lines to mkdocs.yml:

  - search # necessary for search to work
  - mkapi


MkApi provides two modes to generate documentation: Embedding mode and Page mode.

Embedding Mode

To generate the documentation from docstring in a Markdown source, add an exclamation mark (!), followed by mkapi in brackets, and the object full name in parentheses. Yes, this is like adding an image. The object can be a function, class, or module, etc.


You can combine this syntax with Markdown heading:

## ![mkapi](<package.module.object>)

MkApi imports modules that you specify. If they aren't in the sys.path, configure mkdocs.yml like below:

  - search
  - mkapi:
      src_dirs: [<path1>, <path2>, ...]

Here, pathXs are inserted to sys.path. These pathXs are relative to the mkdocs.yml directory.

The embedding mode is useful to embed documentation of an object in an arbitrary position of a Markdown source. For more details, see:

Page Mode

Using the page mode, you can construct a comprehensive API documentation for your project. You can get this powerful feature by just one line:

  - API: mkapi/api/mkapi
