Nuvom

Nuvom gives developers a task engine they can trust clean APIs, zero magic, and predictable behavior from local dev to production scale.

Nuvom is a developer-first background task engine for Python. It lets you queue, schedule, and persist background jobs with predictable behavior without depending on heavyweight infrastructure.

When you need more power, Nuvom’s pluggable backend architecture lets you integrate with SQLite, PostgreSQL, Redis, RabbitMQ, or your own backend for advanced workflows and scaling.

Why Nuvom?

Nuvom is built for developers who want a clear, reliable, and flexible task system that scales with their needs — from a single-machine project to production-grade deployments.

It’s designed for:

  • Developers and teams who want simplicity without giving up control
  • Plugin authors who need a modular, testable task engine
  • Cross-platform environments — consistent behavior on Linux, macOS, and Windows
  • Predictable production workflows with static discovery, manifest caching, and clean observability
  • Advanced setups that need pluggable backends for durability and scale

Key Features

  • Clean task API with @task, .delay(), .map(), and .schedule()
  • Pluggable architecture — SQLite, Postgres, Redis, RabbitMQ, or custom backends
  • Static task discovery — AST-powered, no runtime imports needed
  • Multiple scheduling modes — one-off (at / in_), interval, cron
  • Durable job execution — retries, timeouts, and predictable failure handling
  • Plugin loader with .toml registry for easy extension
  • Observability built-in — job metadata, tracebacks, and optional Prometheus metrics
  • Typed configuration via .env and Pydantic
  • Cross-platform — Python 3.8+ on Linux, macOS, and Windows

Example: Scheduling a Task

from datetime import timedelta
from nuvom.task import task

@task(retries=2, retry_delay_secs=5, timeout_secs=3)
def send_reminder(user_id):
    print(f"Reminder sent to user {user_id}")

# Run once in 5 minutes
send_reminder.schedule(123, in_=timedelta(minutes=5))

# Run every hour
send_reminder.schedule(123, interval=3600)

# Cron-style: every Monday at 9am UTC
send_reminder.schedule(123, cron="0 9 * * MON")
