User Experience Needs
Interactivity and Responsiveness: If your application requires high interactivity and users expect a desktop-like experience with immediate feedback and minimal loading time, an SPA can be highly effective. SPAs are excellent for applications where the user needs to perform frequent actions without reloading the page, such as dynamic dashboards, real-time monitoring tools, or intensive data entry applications.
Single Workflow: Consider an SPA if your application guides users through a singular workflow or task-oriented process where a seamless user journey is critical, such as in form submissions, complex calculations, or user account management.
