Answer 1

Following correction to the import statement works fine:

import jwt_decode from 'jwt-decode';

Update (November 2023): As pointed out in the comments, the package jwt-decode no loger has a default export. Therefore the correct import statement is now:

import { jwtDecode } from 'jwt-decode';

Answer 2

For Angular 17 and newer you will need to import a named export instead (as @Jared Smith said)

import { jwtDecode } from 'jwt-decode';

Answer 3

As said by Nico you have to import a named export instead, using Angular 17 and newer. However I had to use the slightly different line of code for making it run properly:

import {jwtDecode } from 'jwt-decode';
