Hello, thanks for answering ... I do not speak English ... I speak Spanish ... but can you help me with the google translator ... can you show me an example of what I ask in the forum?
Okay, if i were in your shoes, i'd use localstorage or cookies.
but I prefer localstorage.
normally you will be getting a token from the backend when you are logging users right? so just do it this way:
this will be at the point of logging in users
axios.post ('url', {
user,
})
.then (response => {
localStorage.setItem ('token', 'randomstringtokentopersistdata');
then on your dashboard page, just go like this.
const token = localStorage.getItem ('token');
you can store this token in a state and use it all over your app as it can be accessed anywhere.
I understand friend ... I have a doubt ... how are global variables handled in Reactjs ?? that is ... if I want to save and be able to use the variable == >> const name = '' in ALL my application; that variable will take a value when the user enters the system ... and from another component I want to use it ... that is, I want to get the value of that variable name ... can you help me?
You can store that variable in state and pass it as props to whatever component you need it(you'll need to read more on passing props) React official documentation is the best place to start.
Moreover, you'll reach a stage where passing this supposed variable from one component to another will be a pain in the ass, then you should use a state management, the popular one is redux. You'll need to go learn redux too. But for now, since you're just starting to learn react, try learning how to pass state as a props from one component to another.
Let me know if you need more clarification.

I understand friend ... and how do you manage the session expiration time?
You can use JavaScript session storage
sessionStorage.setItem('token', 'randomstring')
const data = sessionStorage.getItem('token');
// to remove user data from sessionStorage
sessionStorage.removeItem('token');
