HTTP Application Example

import json
from asgify.app import Asgify
from asgify.context import HTTPContext
from asgify.status import HTTP_200_OK, HTTP_201_CREATED, HTTP_404_NOT_FOUND, HTTP_STATUS_CODES


async def http_handler(ctx: HTTPContext):
    # Get path and method
    path = ctx.path
    method = ctx.method

    if path == "/" and method == "GET":
        await ctx.start(HTTP_200_OK, {"content-type": "application/json"})
        await ctx.end(json.dumps({"message": "Hello from asgify!"}).encode())

    elif path.startswith("/users/") and method == "GET":
        user_id = path.split("/users/")[-1]
        page = ctx.params.get("page", "1")

        await ctx.start(HTTP_200_OK, {"content-type": "application/json"})
        await ctx.end(
            json.dumps({"user_id": user_id, "page": page, "status": "active"}).encode()
        )

    elif path == "/api/data" and method == "POST":
        # Read JSON body
        body = b""
        async for chunk in ctx.read_body():
            body += chunk

        data = json.loads(body.decode())

        await ctx.start(HTTP_201_CREATED, {"content-type": "application/json"})
        await ctx.end(json.dumps({"created": True, "data": data}).encode())

    else:
        await ctx.start(HTTP_404_NOT_FOUND, {"content-type": "text/plain"})
        await ctx.end(HTTP_STATUS_CODES[HTTP_404_NOT_FOUND].encode())


app = Asgify(http=http_handler)

To run the HTTP server example above using uvicorn, save the code to a file (for example, showcase_http.py) and run the following command in your terminal:

uvicorn showcase_http:app

WebSocket Application Example

import json
from datetime import datetime

from asgify.app import Asgify
from asgify.context import WebSocketContext
from asgify.errors import ClientDisconnected


async def websocket_handler(ctx: WebSocketContext):
    await ctx.accept()
    await ctx.send_bytes("Welcome to asgify 🚀".encode())
    while True:
        try:
            data = await ctx.receive_text()
            print("<", data)
            reply = json.dumps({"echo": data, "timestamp": datetime.now().isoformat()})
            await ctx.send_text(reply)
            print(">", reply)
        except ClientDisconnected:
            print("disconnected with client")
            break

app = Asgify(websocket=websocket_handler)

To run the WebSocket server example above using uvicorn, save the code to a file (for example, showcase_websocket.py) and run the following command in your terminal:

uvicorn showcase_websocket:app

Testing with wscat:

❯ wscat -P -c http://localhost:8000
Connected (press CTRL+C to quit)
< Welcome to asgify 🚀
> hehehe
< {"echo": "hehehe", "timestamp": "2025-07-08T13:06:34.899579"}
> %

✨ Cool Features

🚀 Zero Overhead

• Pure ASGI implementation with minimal dependencies
• No magic, no hidden costs - what you write is what you get

🎯 Context Classes That Rock

The python web framework out there has the same style, but asgify is different because it uses Context to handle requests and responses!

# HTTP Context - Simple & Powerful
await ctx.start(HTTP_200_OK, {"content-type": "application/json"})
await ctx.end(json.dumps({"message": "Hello World"}).encode())

# WebSocket Context - Real-time Ready
await ctx.accept()
message = await ctx.receive_text()
await ctx.send_text(f"Echo: {message}")

🎨 Customizable Everything

• Swap context classes for your needs
• Custom lifespan handlers for app lifecycle
• Full control over request/response flow

📦 Minimal Dependencies

• Only asgiref, fast-query-parsers and multidict
• No bloat, no surprises

🔧 Developer Experience

• Clean, intuitive API
• Comprehensive status codes (HTTP + WebSocket)
• Built-in query parameter parsing
• Application state management
