SharePoint Framework in 2025: new possibilities for development

When Microsoft introduced the SharePoint Framework (SPFx), the goal was clear: to provide developers with a modern model, based on web technologies, to extend SharePoint Online without relying on server-side solutions.
Today, in 2025, SPFx has become the de facto standard for building web parts, extensions, and integrated applications not only in SharePoint but also in Microsoft Teams and the Microsoft 365 ecosystem.

In this article, we will explore the main new features, the best development practices, and the value that SPFx brings to companies looking for a modern, accessible, and integrated intranet.

Evolution of SPFx until 2025

• React 18 and 19: now fully supported, with improvements in performance and rendering.
• Fluent UI v9: new design system consistent across the entire Microsoft 365 suite.
• Teams personal apps: SPFx web parts can be packaged as Teams apps, with a single multi-channel development.
• Improved support for Graph API: more efficient queries, caching, and reduced throttling limits.
• Simplified deployment: thanks to GitHub Actions and Azure DevOps, production releases are faster.

Why SPFx Remains Central

Many wonder: with Copilot and the new integrated AIs, does it still make sense to develop in SPFx?
The answer is yes, because SPFx is not just a framework: it is the bridge between business data and customized user interfaces.

With SPFx you can:

• Create custom dashboards for specific departments.
• Integrate data from ERP/CRM directly into SharePoint.
• Build widgets for Teams that leverage the same libraries.
• Apply branding and business logic without sacrificing updates and cloud compatibility.
