In this tutorial, you'll learn about Versioning Documentation. We cover key concepts, practical examples, and best practices to help you understand and apply this topic effectively.
Versioned API documentation ensures consumers can find the right documentation for their target version, with clear Migration paths between versions.
| Documentation Type | Purpose |
|---|---|
| Versioned reference | Per-version API reference |
| Changelog | All changes across versions |
| Migration guide | Step-by-step upgrade instructions |
| Version matrix | Supported versions chart |
class VersionedDocs:
def __init__(self, base_url: str):
self.base_url = base_url
self.versions: Dict[str, str] = {}
def add_version(self, version: str, doc_path: str):
self.versions[version] = doc_path
def get_doc_url(self, version: str) -> str:
return f"{self.base_url}/{self.versions.get(version, 'latest')}"
def generate_version_selector(self) -> str:
options = "".join(f'<option value="{v}">{v}</option>' for v in self.versions)
return f'<select class="version-select">{options}</select>'
docs = VersionedDocs("https://docs.example.com/api")
docs.add_version("v1", "v1/reference")
docs.add_version("v2", "v2/reference")
print(docs.generate_version_selector())
