fastapi-versioning

api versioning for fastapi web applications

Examples

from fastapi import FastAPI
from fastapi_versioning import VersionedFastAPI, version

app = FastAPI(title='My App')

@app.get('/greet')
@version(1, 0)
def greet():
  return 'Hello'

@app.get('/greet')
@version(1, 1)
def greet():
  return 'Hi'

app = VersionedFastAPI(app)

this will generate two endpoints:

/v1_0/greet
/v1_1/greet

as well as:

/docs
/v1_0/docs
/v1_1/docs
/v1_0/openapi.json
/v1_1/openapi.json

Try it out:

pip install pipenv
pipenv install --dev
pipenv run uvicorn example.app:app

Usage without minor version

from fastapi import FastAPI
from fastapi_versioning import VersionedFastAPI, version

app = FastAPI(title='My App')

@app.get('/greet')
@version(1)
def greet():
  return 'Hello'

@app.get('/greet')
@version(2)
def greet():
  return 'Hi'

app = VersionedFastAPI(app,
    version_format='{major}',
    prefix_format='/v{major}')

this will generate two endpoints:

/v1/greet
/v2/greet

as well as:

/docs
/v1/docs
/v2/docs
