I am trying to integrate okta with webpack and angular2, I am using almost everything correctly and I end up with error. I am using setup from as it is and also followed things correctly mentioned at

i tried to import okta-sign-in.min.js in vendor.ts as well in okta.service.ts with

import '@okta/okta-signin-widget/dist/js/okta-sign-in.min';

You definitely not following the steps. There's no significance of this line at all.

import '@okta/okta-signin-widget/dist/js/okta-sign-in.min';

okta-sign-in.min is a javascript which needs to be included either in index.html. If you are using angular-cli, then as mentioned in tutorial

"scripts": [

All steps in tutorial are correctly mentioned.

Step 1: Create 1 service

declare let OktaSignIn: any;

This line will be needed, intialize the constructor here as per need.

Step 2: calling this service in whatevercomponent.component.ts.

ERROR ReferenceError: OktaSignIn is not defined, with import '#okta/okta-signin-widget/dist/js/okta-sign-in.min'; file gets imported but still i get OktaSignIn is not defined error Thanks for any help in advance. a) To upgrade gulp to v4 - to me, that's not an option, and I don't want to re-write and re-config my frontend toolchain for Xth time. b) To downgrade Node to v11 - is also not an option to me, I don't want to jump through nvm hoops or even think about juggling node environments c) To pin graceful-fs to version 4.2.2 that's known to work under

var OktaSignIn = require('@okta/okta-signin-widget');

just read somewhere it happens because of tslint not webpack

This requires a combination of correct typings and correct library integration. Okta unfortunately doesn't make this easy or clear in their docs or library maintainer responses to issues on their Github repository.

@parth-ghiya was most of the way there but his approach lacks typing support.

Here are my typings so that I can use the widget as a global (ambient) type.

declare class OktaSignIn {
  constructor(configuration: OktaSignInConfig);

interface OktaSignIn {
  renderEl(configuration: { el: string }): void;
  remove(): void;

  session: {
    get: (callback: (repsonse: any) => void) => void;

interface OktaSignInConfigAuthParams {
  issuer: string;
  display: 'page';
  scopes: string[];
  responseType: string[];

interface OktaSignInConfigi18n {
  en: {
    'primaryauth.username.placeholder': string;
    'primaryauth.username.tooltip': string;
    'error.username.required': string;
    'error.password.required': string;

interface OktaSignInConfig {
  baseUrl: string;
  logo: string;
  clientId?: string;
  redirectUri?: string;
  authParams: OktaSignInConfigAuthParams;
  i18n: OktaSignInConfigi18n;

Getting a strange 'OktaSignIn is not a constructor'?, Awesome, thanks resolved the not-a-constructor error. Next problem I'm getting is with the okta-signin-widget: $.cookie is not a function. Variable not declared foo.substring(1); // ReferenceError: foo is not defined The "foo" variable isn't defined anywhere. It needs to be some string, so that the String.prototype.substring() method will work. var foo = 'bar'; foo.substring(1); // "ar" Wrong scope. A variable needs to be available in the current context of execution.

  • Why did you used obfuscated libraries as sources?
  • i guess u will be able to load it via some webpack plugins. here is one of the module . Post your webpack config.
  • since i am using webpack can not directly include script in index file and i am not using angular-cli hence no place to add "scripts": [ "../node_modules/@okta/okta-signin-widget/dist/js/okta-sign-in.min.js" ], and import '@okta/okta-signin-widget/dist/js/okta-sign-in.min' is for importing library which does the job correctly
  • no that import wont work because okta-sign-in.min doesnt export anything. its a JS
  • in one of my other service in same project i used import 'aws-sdk/dist/aws-sdk'; declare const AWS: any; it worked. i believe even aws-sdk is a js which does not export anything, its a way to import entire module without importing any member, since there is no from. i got one temporary fix
  • probably its typings would have been present.!! you can import only if those modules are exported.
