How to Consume REST APIs Without Breaking Your App | Fetch, View Models & 3-Layer Architecture

In this lesson, we break down the exact pipeline professional developers use to consume REST APIs cleanly and safely — no more blank screens, no more "cannot read properties of undefined." We cover everything from reading API contracts like a pro, to safe data extraction, to building a view model that insulates your UI from backend changes. Plus the three-layer architecture that makes your codebase actually maintainable. What we cover: → The API contract: docs, endpoints, and JSON response shape → URLSearchParams vs manual string concatenation → Why fetch doesn't throw on 404s and how to fix it → Optional chaining for safe nested data access → Nullish coalescing vs logical OR (and why it matters) → Building a view model to decouple your UI from raw JSON → The 3-layer architecture: services, transform, and UI → Robustness checklist before shipping any API integration Early access to the build&ai platform → Coming soon 🔔 Subscribe — we drop 3 new lessons every week.
