In order to use Celery with Flask in Python, you need to install a few packages. First, make sure that you have Python 3 installed. Then, open up your terminal and type:
$ pip install celery flask redis This will install the necessary packages for using Celery with Flask in Python - Celery, Flask and Redis.
Once all of these packages are installed, you can move on to creating a new project directory for your application.
Create a new project directoryIn this step, we will create a new project directory for our Flask and Celery application. To do so, open up your terminal or command prompt and type the following commands:
mkDIR flask-celery-project
cd flask-celery-projectNow that you have installed the necessary packages and created a new project directory, it's time to change into the newly created directory. To do this, open up your terminal or command line and type in
cd [project_directory]In order to use Celery with Flask in Python, you need to create two separate files: one for Celery and the other for Flask. To do this, open your text editor of choice and create a new file called celery_app.py. This will be the main file that contains all of your Celery tasks. Then, create another file called flask_app.py, which will contain all of your Flask code.
Once both files have been created, you can start writing code inside them. For example, in celery_app.py, you can write a simple task like this:
@celery_app.task(name="my-task")
def my_task():
print("This is my first task!")
flask_app.py, you can add some basic routes like this:
