nobspy 0.1.16

A project that makes it easier to develope and deploy Python projects

NoBS Python

Define your architecture in pure Python-servers, workers, scheduled jobs, and databases connect automatically through type hints.

Overview

NoBS is a Python framework that eliminates configuration overhead by using type hints to automatically wire up your infrastructure. Write pure Python code and let NoBS handle the connections between servers, workers, databases, and scheduled jobs.

No YAML. No configuration files. Just Python.

Features

• Type-hint driven - Your type annotations define your architecture
• Automatic dependency injection - Components connect without manual wiring
• Pure Python - Everything is code, nothing is configuration
• Full IDE support - Autocomplete and type checking work out of the box
• Minimal boilerplate - Focus on your logic, not setup

Installation

pip install nobs

Quick Start

from nobspy.models import Project, FastAPIApp, Worker
from nobspy.secrets import SlackWebhook

from my_app.settings import AppSettings
from my_app import app

background_worker = Worker("background")

project = Project(
    name="my-custom-server",
    shared_settings=[AppSettings],

    workers=[background_worker],

    my_server=FastAPIApp(app),
)

How It Works

NoBS uses Python type hints to understand your application's resources and automatically creates the necessary connections. When you annotate a settings class with a type like PostgresDsnor RedisDsn, NoBS:

1. Detects the dependency through type
2. Instantiates the component with appropriate configuration
3. Injects it into your environment

Core Components

Server

from nobspy.models import Project, FastAPIApp, Worker
from nobspy.secrets import SlackWebhook

project = Project(
    name="my-custom-server",

    custom_network_app=NetworkApp(
        command=["/bin/bash", "-c", "uv run main.py"],
        port=8000,
    ),
)

Worker

from nobspy import Worker

worker = Worker("name-of-worker")

worker.run(function, Args(...))

Database

from pydantic import PostgresDsn, RedisDsn, BaseModel
from nobspy import Database

class MyAppSettings(BaseModel):
    redis_url: RedisDsn
    psql_db: PostgresDsn

Scheduled Jobs

from nobspy.models import Compute, Project, Job

from my_app.train import train_model, TrainConfig

project = Project(
    name="ml-example",

    train_pokemon_model=Job(
        train_model,
        cron_schedule="0 3 * * *",  # Runs daily at 3 AM
        arguments=TrainConfig(...),
    ),
)

Requirements

• Python 3.10+
• Type hints support

Development

Setup

git clone https://gitlab.com/MatsMoll/nobs.git
cd nobs

python -m venv .venv
source .venv/bin/activate

uv sync

Running Tests

pytest

Type Checking

mypy nobs

Examples

Check out the examples directory for complete applications:

• Simple web server
• Background worker with scheduling
• Full-stack application

Why nobs?

Traditional frameworks require configuration files, manual wiring, and boilerplate code. nobs leverages Python's type system to eliminate this overhead:

Before (traditional approach):

# config.yaml
database:
  host: localhost
  port: 5432

After (nobspy):

class MyApp(BaseModel):
    psql_uri: PostgresDsn
