javascript - How to check the token in localStorage is valid or not?

one text

Solution:

You need to do following code for securing pages

• Add token in redux or localstorage
• On refresh, call api and send token to server that will validate your token
• If validated then you can show protected page otherwise redirect to login
• On server side make middleware that will check if request has token and its valid
• If not valid, send unauthorized response that you can intercept with axios if you are using axios. Or create middleware for response in reactjs

I think this can solve your problem of authenticating user
