Welcome to DeclarativeX 🚀


Hey there! Welcome to the official documentation of DeclarativeX. If you're tired of writing boilerplate code for HTTP clients and want a more declarative approach, you're in the right place. DeclarativeX is designed to make your life easier, letting you focus on what really matters—your application logic.


Getting started with DeclarativeX is a breeze. Just run the following command:

pip install declarativex

And boom! You're good to go.

Available extras

DeclarativeX comes with a few extras that you can install separately. Here's a list of available extras:

  • http2 - HTTP/2 support
  • graphql - GraphQL support
  • brotli - Brotli compression support

To install an extra, just add it to the end of the command:

pip install declarativex[http2,graphql,brotli]
pip install declarativex[http2]

Quick Start Guide

Ready to dive in? Here's a quick example to get you started:
from declarativex import BaseClient, http

@http("GET", "/users/{user_id}", "")
def get_user(user_id: int) -> dict:

response = get_user(user_id=1)
import asyncio

from declarativex import BaseClient, http

@http("GET", "/users/{user_id}", "")
async def get_user(user_id: int) -> dict:

response =

You should see the following output:

  "id": 1,
  "name": "John Doe"


DeclarativeX supports both synchronous and asynchronous HTTP requests. Just define your function as async and you're good to go.

See? No fuss, just clean and straightforward code.

Why DeclarativeX?

  • Less Boilerplate: No more repetitive code for HTTP methods.
  • Type-Safe: Built with type annotations for better code quality.
  • Flexible: Easily extendable to fit your specific needs.
