When should I use localStorage?

Question

To keep it short, here's the only situation in which you should use local storage: when you need to store some publicly available information that is not at all sensitive, doesn't need to be used in a high performance app, isn't larger than 5MB, and consists of purely string data.

Is it good to use local storage?

In summary, LocalStorage is a good and secure way to store publicly accessible, non-sensitive data that can be converted to a string, is less than 5 MB in size, should not be accessible by workers, and is not accessed often. Otherwise, other options should be considered.

Should I use localStorage or sessionStorage?

localStorage and sessionStorage are almost identical and have the same API. The difference is that with sessionStorage , the data is persisted only until the window or tab is closed. With localStorage , the data is persisted until the user manually clears the browser cache or until your web app clears the data.

When should I use localStorage over cookies?

For most cases, we use the localStorage object if we want some data to be on the browser. If we want it on the server, then we use cookies, and the sessionStorage is used when we want to destroy the data whenever that specific tab gets closed or the season is closed by the user.

When should I use local storage vs IndexedDB?

localStorage is useful for storing smaller amounts of data, it is less useful for storing larger amounts of structured data. So if you want to store significant amounts of structured data then IndexedDB is what you should choose.
