fastapi-versioning

api versioning for fastapi web applications

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)

/v1_1/greet

as well as:

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