Controlling the view or API access

DoS attacks happen when a user maliciously accesses a web page or API multiple times to disrupt the traffic and make the resources inaccessible to others. Flask-Limiter can provide an immediate solution by managing the number of access of a user to an API endpoint. First, install the Flask-Limiter module using the following pip command:

pip install flask-limiter

Also, install the module dependency for caching its configuration details to the Redis server:

pip install flask-limiter[redis]

Now, we can set up the module’s Limiter class in the create_app() factory method, like in the following snippet:

from flask_limiter import Limiter
from flask_limiter.util import get_remote_address
def create_app(config_file):
    app = Flask(__name__,template_folder= '../modules/pages', static_folder=   '../modules/resources')
