Flask-RQ2 VS flask-apscheduler

From experience i would not use threads for this or any background jobs. I would use Celery or Flask-RQ2 to be your workers, you will also probably end up using them to run other tasks as you encounter the need for other jobs. They both use Redis as a broker and job store and you can use Redis for other things like caching and so many other useful features. I kind of like RQ2 more then Celery because its a little simpler but Celery has a lot more to offer, more features. RQ2 has rq-dashboard for monitoring jobs and Celery has Flower.

However, you might need to access the app’s context like how you’d do so in the Flask-RQ2 extension by using ScriptInfo from flask.cli:

For the CLI part, i recommend going with Click. Its great and already part of flask and easy to use. Other CLI libraries work too but why have more libraries. For scheduling jobs you might want to look at Flask-APScheduler. i used it in one of my projects at work for a while but ended up needing something that could scale to many more workers so had to rip it out but i didnt have a problem with it otherwise. You might want to fork Flask-APScheduler so you can update some libraries because it hasnt been touched in 2 years now or you can just use APScheduler alone. Flask-RQ2 and Celery are pretty good too but the workers need to run in separate processes and need Redis. You could use Redislite i think and with celery you could use a database as your broker, i have done it but dont recommend it.

I had to use it because I setup scheduled tasks in my init.py. Flask APScheduler

When I’ve previously made bots, I’ve typically used an external service such as Render’s cron job service or Google’s cloud scheduler to handle the timing of my bots. But for @noun__verb, I used flask-apscheduler to set up the timing. This might be better for smaller projects, but you may want to consider a cloud service as you scale.

Hopefully, this can be a starting point for you to get started with generating refresh tokens. As a next step, if you are using Flask you may want to consider using a schedular to update your refresh tokens regularly in an automated fashion. Additionally you may want to consider saving your tokens to a database in a secure fashion. This code sample can also be extended to allow you to connect to any of the endpoints that support v2 and can be deployed to a server as part of a more complete application.

Flask-APScheduler might be what you're looking for.

Any framework to add dynamically job scheduling like cron ? I find https://github.com/viniciuschiele/flask-apscheduler . Anything else like this?

Flask-APSScheduler would work well for this.

To extend this, there is flask wrapper for apscheduler. I worked with this, and it's OK IMO. https://github.com/viniciuschiele/flask-apscheduler
