nautica 3.1.3

A service management framework

Nautica V3

Nautica V3 (or N3) is a backend platform for Python. It gives you a managed runtime environment with a service registry, lifecycle system, CLI, and built-in tools, saving you time from putting your app together and giving you more time to build it.

What's Included

• Service Registry with dependency resolver
• Lifecycle hooks for install, start and shutdown
• TOML Config system with key management
• Logger with file output and memory
• Shell for interacting with services
• TUI for live logs, thread and worker inspection (optional)
• Plugin system for extending projects without modifying core code
• Many Built-in Services, including HTTP API

I made N3 because I was solving the same problems in my projects, those being: configs, logging, figuring out startup orders, not to mention the validation boilerplate on every route. Because of this I made Nautica V2, which solved many of these issues, and V3 to improve on the idea.

Get Started

Firstly, install Nautica:

pip install nautica

To create a project, use the CLI (docs):

nautica create my-project
cd my-project
nautica run

To setup an existing project:

cd my-project
nautica install
nautica run

How HTTP API Compares

Benchmark Performance

Library	Requests/Second	Avg Latency	Overall
Nautica3	2271	4.4ms	-
FastAPI	2259	4.4ms	0.5% slower
Flask	75	132.6ms	96% slower

Ran with 10 workers, for 10 seconds. Nautica3 matches FastAPI despite running additional middleware, requirement parsing, and logging on every request.

Code Complexity

Similarly to SvelteKit, Nautica defines the route names for you. This helps to reduce boilerplate (see Flask and FastAPI examples), improve readability, and helps with naming conventions

Nautica3

# file: src/http/api/v1/auth.py
from napi.http import HTTP, Context, Reply
from somewhere import username, password

@HTTP.POST()
@HTTP.Require(body = {"username": str, "password": str})
def login(ctx: Context):
    if ctx.body["username"] == username and ctx.body["password"] == password:
        return Reply(ok=True)
    return Reply(ok=False, error="Invalid credentials"), 401

Flask

# file: main.py
from flask import Flask, request
from flask.blueprints import Blueprint
import json
from somewhere import username, password

app = Flask(__name__)
v1auth = Blueprint("v1auth", __name__, url_prefix="/api/v1/auth")

@v1auth.post("/login")
def login():
    data = request.get_json(silent=True) or {}
    if data.get("username") == username and data.get("password") == password:
        return json.dumps({"ok": True})
    return json.dumps({"ok": False, "error": "Invalid credentials"}), 401

app.register_blueprint(v1auth)
app.run(port=8101)

FastAPI

# file: main.py
from fastapi import FastAPI, HTTPException
from pydantic import BaseModel
import uvicorn
from somewhere import username, password

app = FastAPI()

class LoginRequest(BaseModel):
    username: str
    password: str

@app.post("/api/v1/auth/login")
def login(body: LoginRequest):
    if body.username == username and body.password == password:
        return {"ok": True}
    raise HTTPException(status_code=401, detail="Invalid credentials")

uvicorn.run(app, port=8101)
