To store local data, today's browsers support a local storage and a session storage. The difference between the two is that the session storage is only available per tab, and the stored data is deleted once you close the tab with the application. The local storage on the other side stores data across sessions. Even when you close the browser and when you re-open it again, the data of the local storage is still there. It will be there as long until you delete it.
So, the difference between the two is how long the data is stored. Beside that, they work exactly the same. Both can store key/value pairs, and those key/value pairs are stored in plain text.
In this blog post, let's look at how to use the local storage and the session storage in your Blazor App.
