Flask-Limiter provides rate limiting features to flask routes. It has support for a configurable backend for storage with current implementations for in-memory, redis and memcache.
Quickstart
Add the rate limiter to your flask app. The following example uses the default in memory implementation for storage.
from flask import Flask
from flask_limiter import Limiter
app = Flask(__name__)
limiter = Limiter(app, global_limits=["2 per minute", "1 per second"])
@app.route("/slow")
@limiter.limit("1 per day")
def slow():
return "24"
@app.route("/fast")
def fast():
return "42"
@app.route("/ping")
@limiter.exempt
def ping():
return 'PONG'
app.run()Test it out. The fast endpoint respects the global rate limit while the slow endpoint uses the decorated one. ping has no rate limit associated with it.
$ curl localhost:5000/fast
42
$ curl localhost:5000/fast
42
$ curl localhost:5000/fast
