DynamicForms FastAPI Viewsets

Django REST Framework-style viewsets for FastAPI, with optional Celery-backed async execution and a matching Vue/TypeScript client counterpart.

• Python mixins for FastAPI — compose CRUD and bulk endpoints from small, focused mixin classes.
• route_viewset decorator — register a viewset on a FastAPI router with a single decorator call. Handles type resolution, lifecycle management and OpenAPI schema automatically.
• CollectionViewSet — zero-boilerplate in-memory viewset backed by any Python list, set or dict. Great for prototyping and testing.
• CeleryViewSet — delegate all CRUD operations to Celery tasks, for long-running or background processing scenarios (requires the celery extra).
• Bulk operations — first-class support for bulk create, update, partial update and destroy.
• Vue / TypeScript counterpart — mirror mixin classes and a route_rest factory give you a fully typed HTTP client that matches your backend viewset exactly (published separately as @dynamicforms/fastapi-viewsets on npm).

Installation

pip install dynamicforms-fastapi-viewsets

# with Celery-backed viewset support
pip install "dynamicforms-fastapi-viewsets[celery]"

Requires Python 3.10+, FastAPI and Pydantic v2.

Quick example

from fastapi import APIRouter, FastAPI
from pydantic import BaseModel

from fastapi_viewsets.collection_viewset import CollectionViewSet
from fastapi_viewsets.decorators.route_viewset import route_viewset
from fastapi_viewsets.mixins import BulkViewSetMixin


class Item(BaseModel):
    id: int
    name: str


database: dict[int, Item] = {1: Item(id=1, name="First element")}

app = FastAPI()
router = APIRouter()


@route_viewset(router, base_path="/items", pk_field_name="id")
class ItemViewSet(CollectionViewSet[int, Item], BulkViewSetMixin[int, Item]):
    def __init__(self):
        super().__init__(container=database, pk_field="id")


app.include_router(router)
