Good day,

I'm using jwt in my authentication. I already decoded my token but the problem is, I want to check if the token exp is already expired or not.

var decodedToken = localStorage.getItem('user_token');



console.log(decodedToken.exp) // writes 1540360205

Thank you in advance.

It appears that the exp claim of your JWT tokens is bearing a UNIX timestamp, in seconds. To check if a given JWT is expired then you can just compare against the current date as a UNIX timestamp:

var decodedToken = localStorage.getItem('user_token');

if (decodedToken.exp < new Date()/1000) {

    console.log("EXPIRED");

}
