How to use it in node typescript applicaiton

[yhjhoo]

what should I do after the following

var jwtDecode = require('jwt-decode');

I am very new to typescript and node

[DavidRutqvist]

I use it as such:
import * as jwtDecode from "jwt-decode";
and then e.g.
if (this.token && (jwtDecode(this.token).exp >= Math.floor(Date.now() / 1000)))

I'm working in TypeScript, and the return of jwt_decode is {} this is causing the following code to fail:

import jwt_decode from 'jwt-decode';

function getTokenExpirationDate(encodedToken: any) {
let token = jwt_decode(encodedToken);
if (!token.exp) { return null; }

const date = new Date(0);
date.setUTCSeconds(token.exp);

return date;

}

Specifically the token.exp field. I'm curious what type the return should be, and how I can force the typing in my application.

@ignatzami This is happening to me as well. Curious if this library is:

1. Maintained still.
2. If not, what is a viable alternative to check the exp of a JWT.

I would assume Auth0 would maintain this, but 🤷‍♂️

@DevanB Were you able to figure this out?

[RiJung]

this works for me

import JwtDecode from 'jwt-decode';

export function checkExpired() {
    const token = 'INSERT YOUR TOKEN HERE';

    interface TokenDto {
      foo: string;
      exp: number;
      iat: number;
    }

    interface TokenHeaderDto {
      typ: string;
      alg: string;
    }

    const decodedTokenPayloadOld = JwtDecode(token);
    const decodedTokenPayload = JwtDecode<TokenDto>(token);
    const decodedTokenHeaderOld = JwtDecode(token, { header: true });
    const decodedTokenHeader = JwtDecode<TokenHeaderDto>(token, { header: true });
    console.log('decodedTokenPayloadOld :', decodedTokenPayloadOld);
    console.log('decodedTokenPayload :', decodedTokenPayload);
    console.log('decodedTokenHeader :', decodedTokenHeader);
    console.log('decodedTokenHeaderOld :', decodedTokenHeaderOld);
}
