rate-limiter

Implementation of a Rate limiter in Python (https://codingchallenges.fyi/challenges/challenge-rate-limiter)

Pre-requisite

• Docker
• Docker-compose

Installation

Clone the repository: git clone https://github.com/niyazi-eren/rate-limiter

cd rate-limiter

docker-compose run --build --rm -p 8000:8000 python --strategy sliding_db

Usage

docker-compose run --build --rm -p port_number:port_number python --port <port_number> --rate <rate> --strategy <strategy>

For a server running on port 8000 for example:

• You can try curl localhost:8000/limited
• Or curl localhost:8000/unlimited

Example

• Run the app on port 8080 with a rate limit of 20 per minute using the sliding window log algorithm

docker-compose run --build --rm -p 8080:8080 python --port 8080 --rate 20 --strategy log

• Run the app with default options (port 8000, rate 10, and bucket token algorithm)

docker-compose run --build --rm -p 8000:8000 python

Test

There is a bash script to run tests for the sliding window counter algorithm: you need to launch 2 servers with the correct algorithm, one in port 8000 one in 8001

A better way is to use Postman
