Data storage is a vital function for applications that need to monitor the progress of users, make login easier or perform other vital functions. There are several ways to store user data however, the most effective solution will depend on the type of problem you’re trying to solve.
Local storage is ideal for keeping small amounts of information that don’t require instant syncing, for example, login and registration details for users. However, it’s restricted by the size of the hard drive and can only be access via client-side software (and cannot be altered through server-side scripts). Local storage is also prone to losing data if the application is shut down, or if the device is reset.
Database storage is ideal for storing large amounts of data that may require editing. It allows you to keep the track of the data of your users by recording their unique identifiers into the database table and then connecting that identifier to the database. This is more complicated than other storage options for data, but it can be a good fit for large or enterprise applications which require storing the user’s data across multiple sessions.
WebView2 uses UDFs to store information about the browser, including cookies, permissions, and cached resources. The data expires according to the user’s Web and App Activity settings. It’s also possible to be manually cleared by the user using Actions on Google. You must select the UDF that has Write access to the WebView2 to store additional user data. See the WinUI 3.cs file in the WebView2Samples repo for an example of how to do this with ICoreWebView2Environment7.
