Step 0 Pre-Check: Architecture & Track Classification
This document records the formal codebase inspection and classification of 16-rate-limit-gateway.
Detection Evidence
A comprehensive inspection of the repository /Users/avishjain/avishjain9-repos/16-rate-limit-gateway was conducted:
| Artifact Checked | Findings / Content | Classification Evidence |
|---|---|---|
| Directory Name | 16-rate-limit-gateway | Distributed multi-algorithm rate limiting API gateway. |
| Monorepo Packages | packages/core/, packages/store-redis/, packages/oracle/, packages/security/ | TypeScript monorepo with Redis Lua atomic scripts and in-memory fallbacks. |
| Gateway App | apps/gateway/src/main.ts, src/gateway/ | Node.js, Express 5, ioredis, fast-check, zod. |
| Web Console | apps/web/ | React 19, Vite, Tailwind CSS, Recharts dashboard. |
| Test Suite | tests/ (25 test suites) | Vitest integration test suite passing unit, property, and resilience tests. |
Formal Classification
- Primary Classification: Track A & C (Full Stack TypeScript & Distributed Systems Gateway)
- Sub-tracks:
- High-throughput API gateway middleware (Node.js, Express 5, Redis)
- Algorithmic rate limiting engine (Token Bucket, Leaky Bucket, Sliding Window Counter, Sliding Window Log)
- Real-time telemetry monitoring dashboard (React 19, Vite)
Adaptation Rules for This Project
- Backend Focus: Emphasize atomic Redis Lua script execution, memory leak prevention in sliding window data structures, route normalization, and graceful in-memory degradation under Redis partition.
- Algorithm Focus: Detail the time and space complexity trade-offs between Token Bucket (low memory, burst-tolerant) vs Sliding Window Counter (accurate boundary limits) vs Sliding Window Log (zero boundary spikes, memory-heavy).
- Security Focus: Map OWASP API Security Top 10: API4:2023 Unrestricted Resource Consumption, DoS mitigation, and header injection prevention.
