Fastapi run background task on startup

x2 Create two tasks based on task() and start running them. Wait for both of these to be completed before moving forward. The last line of the program asyncio.run(main()) runs main(). This creates what's known as an event loop). It's this loop that will run main(), which in turn will run the two instances of task().FastAPI actually plays very well with Django.

About Fastapi Json LoggingHow to use Flask-APScheduler in your Python 3 Flask application to run multiple tasks in parallel, from a single HTTP request When you build an API endpoint that serves HTTP requests to work on long-running tasks, consider using a scheduler. Instead of holding up a HTTP client until a task is completed, you can return an identifier for the client to query the task status later.start_date — starting point for the interval calculation; end_date — latest possible date/time to trigger on; You can set it to run once every two hours with the following code: sched.add_job(job_function, 'interval', hours=2) You can add in the start and end parameters to ensure the tasks only run in-between the start and end timestamp.For creating a continuously running background task, let us consider Now the good news is that since the background tasks are configured into the IServiceCollection , any types added to the dependency injection container will beBatch Script - Variables, There are two types of variables in batch files.
