What should I do if the incognito mode causes Vue data confusion?

Recently, when developing a front-end project based on the Vue framework, I discovered a problem: when used in incognito (or privacy) mode, the data on the page will be messed up or cannot be loaded.

After investigation, we found that the reason is that in incognito mode, the browser disables cache and cookies, and our Vue framework uses the Vuex plug-in to manage data status, which uses the localStorage cache to store data. . This results in some data states not being stored correctly, or being deleted incorrectly.

So, how to solve this problem?

The first solution is to use sessionStorage to replace localStorage to store data. sessionStorage is a session-based local storage, and the stored data will be automatically deleted after closing the browser window. LocalStorage is a kind of permanent local storage. After the browser is closed, the stored data will still exist. Therefore, using sessionStorage can avoid data confusion problems in incognito mode.

The second solution is to modify the storage method of the Vuex plug-in. We can add judgment in the storage logic of the Vuex plug-in. When the browser is in incognito mode, use the memory cache to store data instead of localStorage. In this way, we can still maintain the correctness of the data state.

In addition to the above two methods, there are some other solutions, such as using IndexedDB instead of localStorage, using a hybrid solution of sessionStorage and IndexedDB, etc. Different solutions are suitable for different scenarios, and developers can choose the appropriate solution according to their specific needs.

In summary, the problem of data confusion in incognito mode is not a problem with the Vue framework, but is caused by the browser's restrictions on cache and cookies. We can use different solutions to solve this problem. No matter which solution is used, we should ensure that our data status is correct under any circumstances.
