Fast Point API

Fast Point API is a framework for building APIs using FastAPI. It provides dynamic collection management and currently integrates with CouchDB. Future updates may include support for additional databases. This package is designed to simplify the creation of APIs for managing collections and CRUD operations.

---

Features

• Automatically generates CRUD endpoints for collections.
• Manages collections in a CouchDB instance, with potential future updates to support other databases.
• Defines data structures using Pydantic schemas.

---

Installation

Install the package via pip:

pip install fast-point-api

---

Getting Started

Here's a quick example to set up your API:

Example Code

from fast_point_api.app_factory import create_app
from fast_point_api.schemas import PizzaModel, DrinkModel

# Define custom models
class MyModel(PizzaModel):
    extra_field: str

# CouchDB connection URL
connection_url = "http://admin:admin@localhost:5984"

# Define collections and models
collections = {
    "pizzas": PizzaModel,
    "bebidas": DrinkModel,
}

# Create the FastAPI app
app = create_app(connection_url=connection_url, models_dict=collections)

Run your app:

uvicorn main:app --reload

CouchDB Manager Example

The CouchDBManager class simplifies database management. Here's how to use it:

from fast_point_api.config import CouchDBManager

# Initialize CouchDBManager
manager = CouchDBManager(connection_url="http://admin:admin@localhost:5984")

# Get existing collections
collections = manager.get_existing_collections()
print(f"Existing collections: {collections}")

# Create or get a database
db = manager.get_db("example_db")

# Delete a specific collection
manager.delete_collection("example_db")

# Delete all collections (excluding system databases)
manager.delete_all_collections(exclude_system_dbs=True)

---

CRUD Operations Example

This package includes generic CRUD operations that you can use directly:

from fast_point_api.schemas import PizzaModel
from fast_point_api.crud import create_item, get_items, update_item

# Example Pizza data
pizza = PizzaModel(
    name="Pepperoni",
    description="Classic Pepperoni Pizza",
    ingredients="Tomato, Cheese, Pepperoni",
    size="Large",
    price=15.99,
    is_vegetarian=False,
)

# Create a new item
new_item = create_item(manager, "pizzas", pizza)
print(f"Created item: {new_item}")

# Retrieve all items
items = get_items(manager, "pizzas")
print(f"Items: {items}")

# Update an item
updated_data = {"price": 12.99}
updated_item = update_item(manager, "pizzas", new_item["_id"], updated_data)
print(f"Updated item: {updated_item}")

---

Configuration

CouchDB Setup

Ensure you have CouchDB running. You can use Docker to start an instance:

docker run -d -p 5984:5984 -e COUCHDB_USER=admin -e COUCHDB_PASSWORD=admin couchdb

---

API Endpoints

The package automatically generates CRUD endpoints for each collection. For example, for a collection named pizzas:

• POST /pizzas/ - Create a new item.
• GET /pizzas/ - Get all items.
• GET /pizzas/{item_id} - Get a single item by ID.
• PUT /pizzas/{item_id} - Update an item by ID.
• DELETE /pizzas/{item_id} - Deactivate an item by ID.

Additionally, generic endpoints are available at /generic/{collection_name}/.
