# Figma Reliability Patterns ## Overview Production reliability patterns for Figma REST API integrations. Figma is an external dependency -- your application must handle its outages, rate limits, and slow responses without cascading failures. ## Prerequisites - Working Figma API integration - Understanding of circuit breaker pattern - Cache or file system for fallback data ## Instructions ### Step 1: Circuit Breaker ```typescript // Prevent cascading failures when Figma is down class FigmaCircuitBreaker { private failures = 0; private lastFailure = 0; private state: 'closed' | 'open' | 'half-open' = 'closed'; constructor( private threshold = 5, // Open after 5 failures private resetTimeMs = 30_000 // Try again after 30s ) {} async execute<T>(fn: () => Promise<T>): Promise<T> { if (this.state === 'open') { if (Date.now() - this.lastFailure > this.resetTimeMs) { this.state = 'half-open'; console.log('[figma-circuit] State: half-open (testing recovery)'); } else { throw new Error('Figma circuit breaker is OPEN -- failing fast'); } } try { const result = await fn(); if (this.state === 'half-open') { this.state = 'closed'; this.failures = 0; console.log('[figma-circuit] State: closed (recovered)'); } return result; } catch (error) { this.failures++; this.lastFailure = Date.now(); if (this.failures >= this.threshold) { ...
