How to use the flask_caching library in Python?

Adding caching functionality to a Flask application is made easy with the Flask-Caching library. Below are the basic steps for using the Flask-Caching library.

1. Install the Flask-Caching library.
2. Install Flask-Caching using pip.
3. Import the Flask-Caching library in a Flask application.
4. import Flask from the Flask library and import Cache from the flask_caching library. Create a Flask application called app and initialize a cache with the app.
5. Configuring cache options:
   You can configure the cache by setting relevant options in the Flask application configuration. Here are some common configuration options:
6. Set the cache type to ‘simple’ and the default cache timeout to 300 seconds (5 minutes) in the app configuration.
7. For more information on configuring additional cache options, refer to the official Flask-Caching documentation.
8. To utilize caching, use the @cache.cached decorator on the function or view where caching is needed. Here is a simple example:
9. @app.route(‘/’)
   @cache.cached(timeout=60) # Set cache timeout to 60 seconds
   def index():
   # Cache logic
   return ‘Hello, World!’
10. In addition to the @cache.cached decorator, you can also use the @cache.memoize decorator to cache functions or views with parameters.

The above are the basic steps of using the Flask-Caching library. By utilizing Flask-Caching, you can easily incorporate caching functionality into your Flask application to enhance its performance and responsiveness.
