How to decode JWT Token payload on client side?

Question

I\'m using a jwt token for authentication and would like to read the payload information on the client-side. Right now I\'m doing something like this:

var payloa         


        

Answer 1

This simple solution returns raw token, header and the payload:

function jwtDecode(t) {
  let token = {};
  token.raw = t;
  token.header = JSON.parse(window.atob(t.split('.')[0]));
  token.payload = JSON.parse(window.atob(t.split('.')[1]));
  return (token)
}
