backstage/mkdocs-monorepo-plugin

✚ This plugin enables you to build multiple sets of documentation in a single Mkdocs. It is designed to address writing documentation in Spotify's largest and most business-critical codebases (typically monoliths or monorepos).

Features

• Support for multiple docs/ folders in Mkdocs. Having a single docs/ folder in a large codebase is hard to maintain. Who owns which documentation? What code is it associated with? Bringing docs closer to the associated code enables you to update them better, as well as leverage folder-based features such as GitHub Codeowners.

• Support for multiple navigations. In Spotify, large repositories typically are split up by multiple owners. These are split by folders. By introducing multiple mkdocs.yml files along with multiple docs/ folder, each team can take ownership of their own navigation. This plugin then intelligently merges of the documentation together into a single repository.

• Support across multiple repositories. Using Git Submodules it is possible to merge documentation across multiple repositories into a single codebase dynamically.

• The same great Mkdocs developer experience. It is possible to run mkdocs serve in the root to merge all of your documentation together, or in a subfolder to build specific documentation. Autoreload still works as usual. No more using symlinks!

Install

It's easy to get started using PyPI and pip using Python:

$ pip install mkdocs-monorepo-plugin

Usage

Take a look in our sample project for an example implementation, or see what it looks like after running mkdocs build.

In general, this plugin introduces the !include syntax in your Mkdocs navigation structure and then merges them together.

# /mkdocs.yml
site_name: Cats API

nav:
  - Intro: 'index.md'
  - Authentication: 'authentication.md'
  - API:
    - v1: '!include ./v1/mkdocs.yml'
    - v2: '!include ./v2/mkdocs.yml'

plugins:
  - monorepo

# /src/v1/mkdocs.yml
site_name: versions/v1

nav:
  - Reference: "reference.md"
  - Changelog: "changelog.md"

# /src/v2/mkdocs.yml
site_name: versions/v2

nav:
  - Migrating to v2: "migrating.md"
  - Reference: "reference.md"
  - Changelog: "changelog.md"

Note that, as of v0.5.2, the *include syntax can be used in place of !include in order to compile any number of mkdocs.yml files that match a glob-like pattern, without having to specify every one individually. For example:

# /mkdocs.yml
site_name: Cats System

nav:
  - Intro: 'index.md'
  - Components: '*include ./components/*/mkdocs.yml'
