pyresponse-paradox 0.2.1

A simple Python package for standardized API responses.

PyResponse-paradox 🚀

A lightweight and structured response builder for Flask and FastAPI applications.

📌 Overview

PyResponse-paradox provides a consistent and structured way to return API responses in Flask and FastAPI applications.
It helps standardize response formats while supporting custom messages, error codes, and flexible status handling.

📖 Features

✅ Standardized JSON response format
✅ Supports both Flask and FastAPI frameworks
✅ Predefined response helpers for common HTTP status codes
✅ Customizable messages, data, and error codes
✅ Fully tested with pytest

📦 Installation

To install PyResponse-paradox, simply run:

pip install pyresponse-paradox

🚀 Usage

🔹 Import & Use in Flask

from flask import Flask
from responses import Ok, BadRequest, NotFound

app = Flask(__name__)

@app.route("/success")
def success():
    return Ok({"user": "John Doe"}, message="Request successful!")

@app.route("/error")
def error():
    return BadRequest(message="Invalid request")

if __name__ == "__main__":
    app.run(debug=True)

🔹 Import & Use in FastAPI

from fastapi import FastAPI
from responses import Ok, NotFound

app = FastAPI()

@app.get("/data")
def get_data():
    return Ok({"id": 1, "name": "Alice"})

@app.get("/missing")
def missing():
    return NotFound(message="Item not found")

##🔧 Response Structure

Every response follows a structured JSON format:

{
    "status": 200,
    "message": "Success",
    "data": {...},
    "error_code": "OPTIONAL"
}

##🛠 Response Builder Function

def build_response(status_code, data=None, message=None, error_code=None):
    response_body = {"status": status_code}

    if message:
        response_body["message"] = message
    if data is not None:
        response_body["data"] = data
    if error_code:
        response_body["error_code"] = error_code

    return JSONResponse(content=response_body, status_code=status_code)
