Flask-Limiter vs Other Rate Limiting Libraries

What are the main differences between Flask-Limiter and other rate limiting libraries?

Flask-Limiter is specifically designed for Flask applications, providing easy integration and configuration. Other libraries may offer broader functionality but can be more complex to set up.

Can you give me an example of how to implement Flask-Limiter?

Sure! To implement Flask-Limiter, you first need to install it using pip. Then, you can set it up in your Flask app like this:

from flask import Flask
from flask_limiter import Limiter

app = Flask(__name__)
limiter = Limiter(app, key_func=get_remote_address)

@app.route('/api')
@limiter.limit('5 per minute')
def api():
    return 'This is a rate-limited API endpoint.'

How does Flask-Limiter handle different rate limits for different users?

Flask-Limiter allows you to define rate limits based on user roles or IP addresses. You can use custom key functions to differentiate users and apply specific limits accordingly.

Are there any performance concerns when using Flask-Limiter?

Generally, Flask-Limiter is efficient, but performance can vary based on your storage backend. Using in-memory storage is faster, while database-backed storage may introduce some latency.
