Dynamic API Rate Limiter

[Okeke12nancy]

What is your article idea?

1. Introduction

• Technologies:
  • Strapi 5: Manage user data and API keys.
  • Node.js & Express: Handle API requests and implement rate-limiting logic.
  • Redis: Track and enforce rate limits efficiently.

2. Project Setup

• Backend Setup:
  • Initialize a Node.js project.
  • Set up Strapi 5 as the CMS for managing users and API keys.
  • Install and configure Redis for fast in-memory data storage.
• Dependencies:
  • Install necessary Node.js packages (e.g., express, redis, axios).

3. Strapi Configuration

• User Management:
  • Create and manage user roles and permissions in Strapi.
  • Implement API key management for users in Strapi.
• Strapi API:
  • Set up API endpoints in Strapi for retrieving user data and API keys.

4. Redis Integration

• Set Up Redis:
  • Install and configure Redis server.
  • Connect Redis to the Node.js application.
• Rate Limit Tracking:
  • Use Redis to store and track API usage per user.
  • Implement Redis commands for incrementing request counts and setting expiration times.

5. Implement Rate-Limiting Logic in Express

• Middleware Creation:
  • Develop an Express middleware to enforce rate limits.
  • Check the user's API usage against their allocated rate limit stored in Redis.
• Dynamic Adjustment:
  • Implement logic to dynamically adjust rate limits based on real-time usage patterns.
  • Factor in user behavior, such as increased API calls during specific times, and adjust limits accordingly.

6. Adaptive Rate Limiting

• Usage Pattern Analysis:
  • Analyze API usage patterns (e.g., peak times, frequent users).
  • Adjust rate limits dynamically based on these patterns.
• Behavior-Based Limits:
  • Set different rate limits for users based on behavior (e.g., higher limits for premium users).
• Real-Time Updates:
  • Use Redis Pub/Sub or similar techniques to update rate limits in real-time as usage patterns change.

What are the objectives of your article?
