wtma 0.1.1

ASGI middleware that logs every IP's geolocation, last visit, reverse DNS and much more!

WTMA: Who touched my app?

WTMA is an ASGI middleware purposed to log every IP on your web app with detailed info. Version: 0.1.0

Features

• Geolocation logging: Log every IP with their geolocation data, such as country, continent. region and city.
• Proxy checking: Verify whether IPs were associated with proxies.
• Hosting checking: Verify whether IPs were associated with hosting and datacenters.
• Last visit: View the dynamic and exact time when an IP hit your app.
• Multiple formats: Log data in either JSON or TOML format.
• Console logging: View brief IP info in the console as well.
• Framework support: Supports all ASGI frameworks (FastAPI, Starlette etc.)

Quickstart

Install the wtma python package

pip install wtma

Implement it to your app

FastAPI exmaple:

from fastapi import FastAPI
from wtma import WTMA

app = FastAPI()

@app.get("/")
def root():
    return {
        "message": "Hello, world!"
    }

# Wrap the app at the end
app = WTMA(app, log_path="log.json", file_format="JSON", log_to_console=True)

Also, here's the signature of the constructor method:

    def __init__(self, app, log_path: str, file_format:Literal["JSON", "TOML"]="JSON", log_to_console:bool=True):

[!NOTE] It's recommended to wrap the app with WTMA class at the end instead of using add_middleware because Starlette, which FastAPI is built on top of, suppresses exceptions raised in middleware's initialization, making it difficult to debug.
