Error encountered when attempting to locate the file declaration for module 'jwt-decode'

Currently, I am utilizing the Visual Studio 2017 template for my Angular project and encountering an issue when attempting to import the 'jwt-decode' module after adding it to package.json. The error (mentioned in the title of my post) arises after executing the following:

import * as jwt_decode from 'jwt-decode';

I have verified that the package has been successfully retrieved via npm.

Despite browsing through other posts and implementing the suggested solutions, I have yet to find a resolution. Any assistance would be greatly appreciated.

Thank you, B

Answer №1

When working with Angular2/4 and JWT, it's important to follow this approach:

import { JwtHelper } from 'angular2-jwt';
jwtHelper: JwtHelper = new JwtHelper();

useJwtHelper() {
  var token = localStorage.getItem('token');

  console.log(
    this.jwtHelper.decodeToken(token),
    this.jwtHelper.getTokenExpirationDate(token),
    this.jwtHelper.isTokenExpired(token)
  );
}
