1. Modern Flat Hub Site Topology
Subsites are obsolete in modern cloud architecture. Today’s SharePoint Online deployments utilize flat site collections associated with parent Hub Sites. This decoupling allows dynamic organizational restructuring without breaking permissions or URL paths.
2. Custom SPFx Extension & Graph Integration
SharePoint Framework (SPFx) allows building responsive React components running securely in the user context. Leveraging AadHttpClient and PnP JS allows SPFx web parts to query external APIs and Microsoft Graph data seamlessly.
Frequently Asked Questions
What are the core architecture best practices for modern SharePoint Online intranets?
Modern SharePoint Online architectures replace legacy flat site hierarchies with flat Hub Site models, custom SPFx web parts, PnP JS Graph API data loading, and Microsoft Purview adaptive protection labels for automatic file isolation.
How do you bypass the 5,000 item list view threshold in SharePoint Online?
Bypassing the threshold requires setting indexed columns prior to reaching 5,000 items, using REST/Graph API indexed filters, partitioning document libraries with modern folder structures, or backing large data stores with Dataverse or Azure SQL.
How does SharePoint Online integrate natively with Microsoft Copilot?
Copilot indexes SharePoint Online content through the Microsoft Graph Semantic Index. Proper permissions hygiene, site access reviews, and Purview sensitivity labels ensure Copilot generates responses using authorized files without oversharing confidential data.
