Manual Refresh
Manual refresh is a user-initiated action in software applications where the user explicitly triggers an update to reload or synchronize data, content, or the user interface. It involves the user clicking a refresh button, pressing a key combination (like F5), or performing a gesture to force the application to fetch the latest information from a server or data source. This contrasts with automatic refresh mechanisms that update content periodically without user intervention.
Developers should learn and implement manual refresh in applications where real-time data is not critical, to reduce server load and bandwidth usage, or to give users control over when updates occur. Common use cases include content-heavy websites (e.g., news sites), dashboards with infrequently changing data, or applications in low-connectivity environments where automatic updates might be disruptive or inefficient. It's also essential for debugging, as it allows users to manually check for changes or errors.
