Runs things in the background.

Background

It runs stuff in the background.

"An elegant decorator-based abstraction around Python 3's concurrent.futures ThreadPoolExecutor class"

— Simon Willison

This module makes it stupidly simple to run things in the background of your application, be it a CLI app, or a web app.

Basic Usage

import time

import background


@background.task
def work():
    # Do something expensive here.
    time.sleep(10)


for _ in range(100):
    work()

Advanced Usage

import time

import background

# Use 40 background threads.
background.n = 40


@background.task
def work():
    time.sleep(10)
    return "Done!"

@background.callback
def work_callback(future):
    print(future.result())


for _ in range(100):
    work()

Installation

$ pipenv install background
