SnapAPI in Production: The Patterns I Wish I'd Known Earlier

The SnapAPI docs are good. They tell you what each endpoint does. What they don't cover is how to use those endpoints in systems that actually run in production — with error handling, caching, concurrency limits, CI integration, and real framework patterns. I've been building with SnapAPI for a while and I wrote down the patterns that made the difference. Here are the most useful ones. 1. Always use environment variables. Never hardcode. // Bad — never do this const client = new SnapAPI ( ' snap_abc123 ' ); // Good const client = new SnapAPI (); // reads SNAPAPI_KEY from env Set it in your platform's secrets manager, not in code. For local dev, .env file (never committed). 2. Error handling: loud in CI, graceful in user-facing code // CI pipeline — fail loudly so you notice broken deploys async function validatePage ( url ) { return client . analyze ( url ); // throws on error → CI step fails } // User-facing feature — fail gracefully async function tryGetPreview ( url ) { try { return
