jwt check if token expired

Question

I've configured the token like this:

jwt.sign(   {     user: pick(user, ['_id', 'username'])   },   secret,   {     expiresIn: '2m'   } ); 

But when I want to check if the token was expired, this code doesn't work:

function isAuthenticated() {   const token = localStorage.getItem('token');   const refreshToken = localStorage.getItem('refreshToken');   try {     decode(token);     const { exp } = decode(refreshToken);     if (exp < (new Date().getTime() + 1) / 1000) {       return false;     }   } catch (err) {     return false;   }   return true; } 

The problem is this part:

if (exp < (new Date().getTime() + 1) / 1000) {   return false; } 

new Date().getTime() + 1) / 1000 = 1531335468.113

exp = 1531334595

Because I don't know what format of time JWT uses...

How can I resolve this?

Answer 1

This is the answer:

if (Date.now() >= exp * 1000) {   return false; }
