Building reliable API integrations in modern web application
Short summary
Modern web applications face inevitable API reliability challenges from failures, timeouts, expired tokens, and scaling limits. Key practices include retry logic, error handling, authentication management, response versioning, and scaling strategies like batching and backoff. Implement these patterns into architecture design from the start rather than as reactive patches after production breaks.
- •API failures, timeouts, and expired credentials require retry logic and error handling built into architecture
- •Response structure evolution and scaling demand versioning, batching, queues, and backoff strategies
- •Design reliability patterns early; they become necessary much sooner than most teams expect
