Single-Page Applications for Microsoft Power Pages reaches GA

Microsoft previewed single-page websites for Power Pages in late 2025 to give developers the option to build code-driven portal applications using Power Platform CLI. Now, the company has announced that the SPA model has reached GA, starting with site version 9.8.1.x and later.

With GA, Microsoft has “resolved issues where Power Pages platform styles could override your custom CSS,” according to principal product manager Neeraj Nandwana. 

Power Platform Git integration is not supported for SPA sites, according to Microsoft documentation.

SPA features were the featured topic of MSDW and Engineered Code’s October 2025 Portals Community Call in which host Nicholas Hayduk and his colleague Allan Rumberger looked at the use cases and implementation of SPAs in Power Pages.

Hayduk explained that SPAs have been part of Power Pages “since the beginning” using different techniques, and have been a common technique for meeting more advanced interface requirements. The Engineered Code team develops them with React or TypeScript that can be bundled as PCF Controls rather than deployed on their own. He noted that SPA developers should be looking to maintain consistency with their broader Power Pages development approach. 

The new SPA functionality for Power Pages can replace an entire site with an SPA and supports both authentication and the Web API. The October webcast recording includes a demo of building and uploading a React-based SPA for Power Pages.

In the end, Hayduk advised the audience that the new technique is lower overhead for launching an SPA. But if all you want is an SPA, there are better ways to create one, such as deploying the app on Azure directly with custom authentication and Web API capabilities.
