hammal 0.1.3

A lightweight HTTP router library providing bare minimum routing functionality, designed for easy embedding within other applications.

Hammal

Hammal is a fast, minimalist Python web framework inspired by Echo. It is designed to be simple and easy to embed within other applications, providing the bare minimum router functionality.

Installation

Install Hammal using pip:

pip install hammal

Quick Start

Here's how you can get started with Hammal:

Example: Hello World

import json
from hammal import Hammal, RequestContext

def hello_handler(context: RequestContext) -> None:
    context.response.body = json.dumps({"message": "Hello, World!"})

router = Hammal()
router.get("/", hello_handler)
router.start()

Run the script and visit http://localhost:8000 in your browser to see "Hello, World!".

Example: Handling Parameters

def greet_handler(context: RequestContext) -> None:
    name = context.path_params.get("name", "Guest")
    context.response.body = json.dumps({"message": f"Hello, {name}!"})

router.get("/greet/:name", greet_handler)

Accessing http://localhost:8080/greet/Pikachu will return "Hello, Pikachu!".

Example: Middleware

import logging

def logging_middleware(context: RequestContext) -> bool:
    logging.info(f"{context.method} request for {context.path} with body: {context.body}")
    return True

def auth_middleware(context: RequestContext) -> bool:
    token = context.headers.get("Authorization")
    if not token == MONITORING_API_KEY:
        context.response.status = 401
        return False
    return True

router.use(logging_middleware)
router.use(auth_middleware)

Example: Extensibility

Hammal is designed to be extensible, allowing you to integrate it into other applications seamlessly. Here's an example of extending Hammal:

from hammal import Hammal

class BotWithHammal(Hammal):
    def __init__(self, bot, *args, **kwargs):
        self.bot = bot
        super().__init__(*args, **kwargs)

    def start_async(self, *args, **kwargs):
        super().start_async(*args, **kwargs)
        self.bot.polling(none_stop=True, timeout=60)

app = BotWithHammal(bot)
# add routes and middlewares
app.start_async()
