SPFx PnPjs: The Developer's Guide to SharePoint REST API Made Easy

PnPjs v3's fluent API eliminates URL construction, header management, and digest token handling — your SharePoint data access code becomes readable and maintainable.

The singleton getSP(context) pattern initialises PnPjs once in onInit() and makes the instance available throughout your component tree without prop drilling.

Batching multiple requests into a single HTTP call is the most effective way to avoid SharePoint throttling in data-heavy web parts.

Remember the side-effect imports in v3 — forgotten imports are the most common source of "method not found" errors when migrating from v2.
