Install

pip install fognode

Quick start (aiogram-style)

Server

from fognode import App, Cipher

app = App(
    host="0.0.0.0",
    port=9443,
    user="alice",
    password="secret",
    cipher=Cipher.AESGCM,
)

@app.on_message()
async def echo(ctx):
    await ctx.answer(f"echo: {ctx.message.text}")

@app.on_command("ping")
async def ping(ctx):
    await ctx.answer("pong")

@app.on_connect()
async def on_connect(ctx):
    print(f"+ {ctx.user}")

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

Client

from fognode import App, Cipher

app = App.client(
    connect_string="alice@oak-pine-stone-field:9443",
    password="secret",
    cipher=Cipher.AESGCM,
)

@app.on_message()
async def on_message(ctx):
    print(f"{ctx.message.user}: {ctx.message.text}")

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

Classic API

from fognode import start_server, client_connect

ip, code, fp = start_server("0.0.0.0", 9443, "alice", "secret")
print(f"Connect: alice@{code}:9443")
