What are some examples of caching in Flask?

Flask provides several caching options. You can use Flask-Caching with backends like Redis or Memcached. Would you like a code example?

Yes, please provide a code example using Redis.

Sure! Here's a simple example:

from flask import Flask
from flask_caching import Cache

app = Flask(__name__)
app.config['CACHE_TYPE'] = 'redis'
cache = Cache(app)

@cache.cached(timeout=50)
@app.route('/data')
def get_data():
    return {'data': 'This is cached data!'}

This caches the response for 50 seconds.

What if I want to cache a function instead of a route?

You can use the @cache.cached decorator directly on the function. For example:

@cache.cached(timeout=60)
def expensive_function():
    # Some expensive computation
    return result

This caches the result of expensive_function for 60 seconds.
