Power Platform: SPFx & Custom List Forms

Key insights

• SPFx: The SharePoint Framework is Microsoft's modern client-side model for building custom experiences across SharePoint, Teams, and Viva.
  It gives developers authenticated APIs, contextual data, and better runtime performance than legacy approaches.
• Demo by Vipul Jain: The demo shows how to combine SPFx, Modern Hillbilly Tabs, and Power Apps list form customization to build a seamless Power Platform experience inside SharePoint.
  The result is a modern interface that keeps users in SharePoint and reduces context switching.
• Modern Hillbilly Tabs: This pattern places multiple web parts into tabbed sections on modern pages to reduce clutter and improve navigation.
  Use it to group related web parts and Power Apps forms for a cleaner page layout.
• Power Apps list form customization: Embed and replace list new/edit/view forms with Power Apps to deliver richer, tailored input and validation.
  The SPFx roadmap aims to make these overrides more direct and flexible inside Lists and Libraries.
• Recent SPFx updates & roadmap: SPFx 1.21 preview added developer environment improvements and Node.js v22 support, plus better flexible layouts and card options.
  Planned enhancements include list form overrides, web part size APIs, Teams store targeting, Viva Connections card improvements, and performance and deployment fixes.
• Practical benefits: Combining SPFx with Hillbilly Tabs and Power Apps delivers a unified, faster user experience and simplifies solution discovery and deployment.
  Teams should adopt these patterns to modernize interfaces and centralize SharePoint-based workflows.

Summary of the Video Demo

The Microsoft YouTube video, presented during the Microsoft 365 & Power Platform weekly call on 25 September 2025, demonstrates how to build a cohesive user experience inside modern SharePoint pages. The presenter walks through combining the SharePoint Framework with the Modern Hillbilly Tabs pattern and Power Apps list form customizations to keep users from leaving the SharePoint context. Consequently, the demo emphasizes a connected interface that blends web parts, tabs, and form experiences for everyday business scenarios. Overall, the session aims to show practical steps and patterns that organizations can adopt quickly.

Technologies Demonstrated

The demo centers on the SPFx extensibility model as the foundation for building web parts and page components that run inside SharePoint Online and related Microsoft 365 surfaces. Additionally, the presenter shows how the Modern Hillbilly Tabs approach can organize web parts into tabbed areas without heavy client-side frameworks, making pages feel modern and compact. Meanwhile, Power Apps list form customizations are used to replace or enhance new, edit, and view experiences directly in lists. Together, these pieces illustrate a pattern where each technology plays a specific role while remaining tightly integrated.

Practical Workflow and Integration

First, the presenter builds or configures SPFx web parts to display content and to expose properties that the tab solution can use to swap views dynamically. Then, the Hillbilly Tabs pattern places those web parts into a tabbed layout so users can switch contexts without page reloads, which improves perceived performance and reduces friction. Finally, Power Apps list form customization is embedded so that list items open with tailored forms while the rest of the page remains intact. Thus, the workflow demonstrates how developers and power users can collaborate: developers supply reusable components while app makers configure forms to match business needs.

Tradeoffs and Challenges

Balancing responsiveness, maintainability, and governance presents significant tradeoffs. On one hand, embedding multiple experiences in a single page improves user continuity and reduces context switching, but on the other hand it can increase page complexity and performance risk if web parts are heavy or not lazy-loaded. Moreover, deep customization of list forms via Power Apps gives business owners flexibility but may complicate lifecycle management, because updates to forms or web parts can produce unexpected interactions. Therefore, teams must weigh short-term user experience gains against long-term maintenance overhead and potential performance costs.

Deployment and Governance Considerations

Deploying this integrated approach requires clear governance and consistent deployment pipelines. For instance, testing combined scenarios is more difficult than testing individual components, since interactions between SPFx web parts and Power Apps forms can reveal timing or data-binding issues that do not appear in isolation. Additionally, organizations must consider permissions, tenant app catalog policies, and solution packaging to ensure reliable rollouts across sites. Consequently, automated CI/CD, performance budgets, and staged rollouts become essential to keep the user experience stable while allowing innovation.

Looking Ahead: Best Practices and Roadmap Fit

The video also highlights why the SPFx roadmap and capabilities matter for these scenarios, because upcoming features that enable deeper list and library customization or better size-aware rendering will reduce some of the current tradeoffs. In the near term, teams should favor modular components, lazy loading, and clear boundaries between web parts and embedded forms to limit coupling. Finally, organizations should plan governance around updates, monitoring, and performance optimization so that the seamless experience shown in the demo scales predictably. By doing so, they can deliver modern, connected interfaces that balance user productivity with maintainability and security.
