This tutorial provides a comprehensive guide on building a request-throttling API using Strapi and Redis, focusing on a blog application example. It explains the concept of request throttling, which limits client requests to a server within a specific timeframe to manage resource utilization effectively. The tutorial covers the implementation of various algorithms, including the fixed window and sliding window algorithms, for request throttling. It also introduces Redis as an in-memory data store to keep track of user requests and describes how to create and configure middleware in Strapi to intercept and limit requests. The guide illustrates how to set up a Strapi project, create API endpoints, authenticate users, and implement custom middleware to manage request limits, using Redis to store request data and Moment.js for time management. The tutorial concludes with practical steps to test the API using a tool like Postman, demonstrating how to handle excessive requests with appropriate error responses.
