Okta React Redux First Router SDK

Okta React Redux First Router SDK builds on top of the Okta Auth SDK. This SDK adds integration with redux-first-router and provides additional logic and components designed to help you quickly add authentication and authorization to your React single-page web application.

With the Okta Auth SDK, you can:

• Login and logout from Okta using the OAuth 2.0 API
• Retrieve user information
• Determine authentication status
• Validate the current user's session

All of these features are supported by this SDK. Additionally, using this SDK, you can:

• Add "secure" routes, which will require authentication before render
• Define custom logic/behavior when authentication is required
• Provide an instance of the Auth service to your components using a higher-order component

This SDK does not provide any UI components.

This library currently supports:

• OAuth 2.0 Implicit Flow
• OAuth 2.0 Authorization Code Flow
• Proof Key for Code Exchange (PKCE)

Getting Started

• If you do not already have a Developer Edition Account, you can create one at https://developer.okta.com/signup/.
• An Okta Application, configured for Single-Page App (SPA) mode. This is done from the Okta Developer Console and you can find instructions here. When following the wizard, use the default properties. They are are designed to work with our sample applications.

Installation

This library is available through npm. To install it, simply add it to your project:

npm install --save @sridi/okta-react-redux-first-router

Usage

okta-react-redux-first-router works directly with react-router-redux-first-router and provides some additional components:

• Security - Allows you to supply your OpenID Connect client configuration. Provides an instance of the Auth service to child components.
• SecureRoute - A normal Thunk except authentication is needed to render the component.
• ImplicitCallback - A simple component which handles the login callback.

Create Routes

Here is a minimal working example. This example defines 3 routes:

• / - Anyone can access the home page
• /protected - Protected is only visible to authenticated users
• /implicit/callback - This is where auth is handled for you after redirection

// src/App.js

import React, { Component } from 'react';
import { Security } from '@okta/okta-react';
import Router from './Router';
import Home from './Home';
import Protected from './Protected';

class App extends Component {
  render() {
    return (
      <Security issuer='https://{yourOktaDomain}.com/oauth2/default'
                clientId='{clientId}'
                redirectUri={window.location.origin + '/implicit/callback'} >
        <Router />
      </Security>
    );
  }
}

export default App;

Show Login and Logout Buttons

In the relevant location in your application, you will want to provide Login and Logout buttons for the user. You can show/hide the correct button by using the auth.isAuthenticated() method. For example:

// src/Home.js

import React, { Component } from 'react';
import { withAuth } from '@okta/okta-react';

export default withAuth(class Home extends Component {
  constructor(props) {
    super(props);
    this.state = { authenticated: null };
    this.checkAuthentication = this.checkAuthentication.bind(this);
    this.login = this.login.bind(this);
    this.logout = this.logout.bind(this);
  }

  async checkAuthentication() {
    const authenticated = await this.props.auth.isAuthenticated();
    if (authenticated !== this.state.authenticated) {
      this.setState({ authenticated });
    }
  }

  async login() {
    this.props.auth.login('/');
  }

  async logout() {
    this.props.auth.logout('/');
  }

  async componentDidMount() {
    this.checkAuthentication();
  }

  async componentDidUpdate() {
    this.checkAuthentication();
  }

  render() {
    if (this.state.authenticated === null) return null;
    return this.state.authenticated ?
      <button onClick={this.logout}>Logout</button> :
      <button onClick={this.login}>Login</button>;
  }
});

Use the Access Token

When your users are authenticated, your React application has an access token that was issued by your Okta Authorization server. You can use this token to authenticate requests for resources on your server or API. As a hypothetical example, let's say you have an API that provides messages for a user. You could create a MessageList component that gets the access token and uses it to make an authenticated request to your server.

Reference

Security

Security is the top-most component of okta-react. This is where most of the configuration is provided.

Configuration options

These options are used by Security to configure the Auth service. The most commonly used options are shown here. See Configuration Reference for an extended set of supported options.

• issuer (required) - The OpenId Connect issuer
• clientId (required) - The OpenId Connect client_id
• redirectUri (required) - Where the callback handler is hosted
• postLogoutRedirectUri | Specify the url where the browser should be redirected after logout. This url must be added to the list of Logout redirect URIs on the application's General Settings tab.
• scope (deprecated in v1.2.3): Use scopes instead
• scopes (optional) - Reserved for custom claims to be returned in the tokens. Default: ['openid', 'email', 'profile']. For a list of scopes and claims, please see Scope-dependent claims for more information.
• responseType (optional) - Desired token types. Default: ['id_token', 'token']. For PKCE flow, this should be left undefined or set to ['code'].
• pkce (optional) - If true, PKCE flow will be used
• onAuthRequired (optional) - callback function. Called when authentication is required. If this is not supplied, okta-react redirects to Okta. This callback will receive auth and history parameters. This is triggered when:
  1. login is called
  2. A SecureRoute is accessed without authentication
• onSessionExpired (optional) - callback function. Called when the Okta SSO session has expired or was ended outside of the application. This SDK adds a default handler which will call login to initiate a login flow. Passing a function here will disable the default handler.
• isAuthenticated (optional) - callback function. By default, auth.isAuthenticated() will return true if both getIdToken() and getAccessToken() return a value. Setting a isAuthenticated function on the config will skip the default logic and call the supplied function instead. The function should return a Promise and resolve to either true or false.

• tokenManager (optional): An object containing additional properties used to configure the internal token manager. See AuthJS TokenManager for more detailed information.

  • autoRenew (optional): By default, the library will attempt to renew expired tokens. When an expired token is requested by the library, a renewal request is executed to update the token. If you wish to to disable auto renewal of tokens, set autoRenew to false.

  • secure: If true then only "secure" https cookies will be stored. This option will prevent cookies from being stored on an HTTP connection. This option is only relevant if storage is set to cookie, or if the client browser does not support localStorage or sessionStorage, in which case cookie storage will be used.

  • storage (optional): Specify the type of storage for tokens. The types are:

    • localStorage
    • sessionStorage
    • cookie

Alternate configuration using Auth instance

When the auth option is passed, all other configuration options passed to Security will be ignored.

• auth (optional) - Provide an Auth service instance instead of the options above. This is the most direct way to use methods on the Auth service instance outside of your components and is helpful when integrating okta-react with external libraries that need access to the tokens.

Configure an instance of the Auth service and pass it to the Security component.

SecureRoute ensures that a route is only rendered if the user is authenticated. If the user is not authenticated, it calls onAuthRequired if it exists, otherwise, it redirects to the Home page.

ImplicitCallback

ImplicitCallback handles the callback after the redirect. By default, it parses the tokens from the uri, stores them, then redirects to /. If a SecureRoute caused the redirect, then the callback redirects to the secured route. For more advanced cases, this component can be copied to your own source tree and modified as needed.

withAuth

withAuth is a higher-order component which injects an auth prop into the component. This provides a way for components to make decisions based on auth state.

auth

auth An object that provides methods for managing tokens and auth state. All of the methods return Promises.

auth.isAuthenticated()

Returns true or false, depending on whether the user has an active access or id token.

auth.getUser()

Returns the result of the OpenID Connect /userinfo endpoint if an access token exists.

auth.getIdToken()

Retrieves the id token from storage if it exists.

auth.getAccessToken()

Retrieves the access token from storage if it exists.

auth.login(fromUri, additionalParams)

Calls onAuthRequired or redirects to Okta if onAuthRequired is undefined. This method accepts a fromUri parameter to push the user to after successful authentication, and an optional additionalParams object.

For more information on additionalParams, see the auth.redirect method below.

auth.logout(uri)

Terminates the user's session in Okta and clears all stored tokens. Accepts an optional uri parameter to push the user to after logout.

auth.redirect(additionalParams)

Performs a full-page redirect to Okta with optional request parameters.

The additionalParams are mapped to Okta's /authorize request parameters. This will override any existing configuration. As an example, if you have an Okta sessionToken, you can bypass the full-page redirect by passing in this token. This is recommended when using the Okta Sign-In Widget. Simply pass in a sessionToken into the redirect method as follows:

auth.redirect({
  sessionToken: '{sampleSessionToken}'
});

Note: For information on obtaining a sessionToken using the Okta Sign-In Widget, please see the renderEl() example.

auth.handleAuthentication()

Parses tokens from the url and stores them.

auth.setFromUri(uri, queryParams)

Store the current URL state before a redirect occurs.

auth.getFromUri()

Returns the stored URI and query parameters stored by setFromUri
