To make it easy for you to get started with GitLab, here's a list of recommended next steps.

import { getAccessToken, setAccessToken } from "./localstorageService";

export const setInvalidStorageToken = () => {
  setAccessToken(invalidToken);

  }
  return false;

    token === undefined ||
    token === null ||
    token === "" ||
    token === "null"
  ) {
    return true;
  }
  return false;
};

export const isGivenTokenExpired = (token) => {
  if (isGivenTokenEmpty(token) === false) {
    return calc(token, 0);

  return undefined;
};

export const isGivenTokenExpiring = (token) => {

};

const calc = (token, diffMins) => {
  const decode = jwtDecode(token);
  const current = Date.now() / 1000;
  const tokenExpiry = decode.exp;
  const secs = 60 * diffMins;
  if (tokenExpiry - current <= secs) {
    return true;

  return false;

export const getStorageToken = () => {
