In this chapter, we looked at various ways to support asynchronous execution in Django. They provide powerful abstractions on top of Django to create applications that can support push notifications, display the progress of a slow task, communicate with other users, or run background tasks.
Traditionally, Celery has been the tool of choice for asynchronous activities. However, Channels provide a lighter and more tightly integrated solution. Both have their uses and can be used in the same project. Use the right tool for the job!
In the next chapter, we will look at what RESTful APIs means and how we can implement them in Django using current best practices.
