How can I improve caching performance in Flask using middleware?

You can use Flask-Caching, a Flask extension that provides caching support. It allows you to cache responses easily.

What types of caching strategies can I implement?

You can implement various strategies like simple in-memory caching, file-based caching, or using a distributed cache like Redis.

How do I set up Flask-Caching with Redis?

First, install Flask-Caching and Redis. Then, configure your Flask app to use Redis as the cache backend.

Can you provide a code example for that?

Sure! Here's a simple example:

from flask import Flask
from flask_caching import Cache

app = Flask(__name__)
app.config['CACHE_TYPE'] = 'redis'
app.config['CACHE_REDIS_URL'] = 'redis://localhost:6379/0'
cache = Cache(app)

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