How do I keep the cache from becoming stale?

You can use the built-in invalidation functions paired with Knack webhooks to clear specific cache keys whenever a record is updated in the database.

Can I use this with production databases like Redis?

Yes, the skill provides implementation patterns for In-Memory development, production Redis instances, and serverless-friendly Vercel KV storage.

What happens when the Knack API returns a 429 error?

The skill utilizes an exponential backoff function that automatically catches rate limit errors and retries the request with increasing delays.

How does this skill handle Knack's rate limits?

It implements a RateLimiter class that ensures a minimum of 100ms between requests, effectively capping outbound traffic at the required 10 requests per second.

API Development

Optimizes Knack API performance by implementing intelligent caching and strict rate-limit enforcement.

The Knack Cache Optimizer is a specialized skill designed to bridge the gap between high-demand applications and Knack's strict API constraints. It enforces the mandatory 10-requests-per-second rate limit using a sophisticated throttling mechanism and reduces operational costs by caching frequently accessed data with configurable Time-to-Live (TTL) settings. Ideal for developers building data-heavy dashboards or reporting tools, this skill ensures stability through exponential backoff retries and supports multiple storage backends including Redis and Vercel KV, making it essential for production-grade Knack integrations.

Key Features

01Configurable TTL caching for dashboards, reports, and reference data

02Real-time monitoring of cache hit rates and API cost savings

03Automatic exponential backoff for resilient API communication

04Support for multiple storage backends: In-Memory, Redis, and Vercel KV

057 GitHub stars

06Strict 10 req/sec rate limit enforcement to prevent 429 errors

Use Cases

01Providing offline-ready data for complex quarterly reporting syncs

02Accelerating high-traffic Knack dashboards with pre-calculated metrics

03Managing large-scale data migrations without exceeding API quotas
