Celery task

pip install celery

A Celery worker must be running to run the task. Starting a worker is shown in the previous sections.

from flask import request
@app.post("/add")
def start_add() -> dict[str, object]:
    a = request.form.get("a", type=int)
    b = request.form.get("b", type=int)
    result = add_together.delay(a, b)
    return {"result_id": result.id}

Here’s an example task that adds two numbers together and returns the result.

from celery import shared_task

@shared_task(ignore_result=False)
def add_together(a: int, b: int) -> int:
    return a + b
