Session: SPFx Unleashed: One Codebase for Enterprise, Host-Aware Apps Across Microsoft 365

SPFx is the most direct, compliant way to ship real software across Microsoft 365—and this demo-driven session shows why. We’ll build an enterprise-grade solution end to end with Fluent UI 9, then run it first-class in SharePoint, Teams, Outlook, and the Copilot Portal, using host detection to adapt theming, density, and capabilities on the fly. Along the way, we’ll reuse PnPjs and PnP React where they add value, wire up Microsoft Graph and external APIs with Entra-backed authentication, and provision the artifacts your rollout actually needs—lists, content types, pages, and assets—so the app lands production-ready in real tenants. Expect practical, field-tested guidance on accessibility, performance, caching, feature flags, error handling, telemetry, packaging, and ALM, all focused on helping you move from fast prototypes to durable, compliant solutions. You’ll leave convinced—and equipped—that SPFx is the best path to building modern, scalable applications across the entire Microsoft 365 stack.
