If you run a quick Google search for persisting a logged-in user in React (or keeping a user logged in in React), you don’t get a lot of straightforward results. There aren’t really any easy to follow examples on how to achieve this. So I decided I had to write that simple guide.

You may have done a search on this and saw the word localStorage being thrown around. Yes, we’ll be using localStorage but I’m going to show you exactly how it’s done.

Some notes on localStorage

1. localStorage is the browser’s database. The data is stored inside your browser in your computer’s memory.
2. **localStorage **is specific to an origin. In other words, the localStorage for one website cannot be accessed by another.
