react-oidc-context-params-redirect

About

Easy set up of OIDC for react and use the new react context api as state management.

Getting Started

npm install react-oidc-context-params-redirect --save

Application startup (index.js)

The library is router agnostic and use native History API.

The default routes used internally :

• www.your-app.fr/authentication/callback
• www.your-app.fr/authentication/silent_callback
• www.your-app.fr/authentication/not-authenticated
• www.your-app.fr/authentication/not-authorized

import React from 'react';
import { render } from 'react-dom';
import { BrowserRouter as Router } from 'react-router-dom';
import { AuthenticationProvider, oidcLog } from '@axa-fr/react-oidc-context';
import Header from './Layout/Header';
import Routes from './Router';
import oidcConfiguration from './configuration';

const App = () => (
  <div>
    <Router>
      <AuthenticationProvider configuration={oidcConfiguration} loggerLevel={oidcLog.DEBUG}>
        <Header />
        <Routes />
      </AuthenticationProvider>
    </Router>
  </div>
);

render(<App />, document.getElementById('root'));

AuthenticationProvider accept the following properties :

const propTypes = {
  notAuthenticated: PropTypes.elementType, // react component displayed during authentication
  notAuthorized: PropTypes.elementType, // react component displayed in case user is not Authorised
  authenticating: PropTypes.elementType, // react component displayed when about to redirect user to be authenticated
  callbackComponentOverride: PropTypes.elementType, // react component displayed when user is connected
  sessionLostComponent: PropTypes.elementType, // react component displayed when user loose authentication session
  configuration: PropTypes.shape({
    client_id: PropTypes.string.isRequired, // oidc client configuration, the same as oidc client library used internally https://github.com/IdentityModel/oidc-client-js
    redirect_uri: PropTypes.string.isRequired,
    response_type: PropTypes.string.isRequired,
    scope: PropTypes.string.isRequired,
    authority: PropTypes.string.isRequired,
    silent_redirect_uri: PropTypes.string.isRequired,
    automaticSilentRenew: PropTypes.bool, //optional, by default to true
    loadUserInfo: PropTypes.bool, //optional, by default to true
    post_logout_redirect_uri: PropTypes.string, // optional
    metadata: PropTypes.shape({
      issuer: PropTypes.string,
      jwks_uri: PropTypes.string,
      authorization_endpoint: PropTypes.string,
      token_endpoint: PropTypes.string,
      userinfo_endpoint: PropTypes.string,
      end_session_endpoint: PropTypes.string,
      revocation_endpoint: PropTypes.string,
      introspection_endpoint: PropTypes.string,
    }),
  }).isRequired,
  isEnabled: PropTypes.bool, // enable/disable the protections and trigger of authentication (useful during development).
  loggerLevel: PropTypes.number,
  logger: PropTypes.shape({
    info: PropTypes.func.isRequired,
    warn: PropTypes.func.isRequired,
    error: PropTypes.func.isRequired,
    debug: PropTypes.func.isRequired,
  }),
  UserStore: PropTypes.func,
};

Through the UserStore you can specify a class that can be used to store the user object. This class must define :

  getItem(key: string): any;
  setItem(key: string, value: any): any;
  removeItem(key: string): any;
  key(index: number): any;
  length?: number;

It could also be window.localStorage or window.sessionStorage. By default, without any userStore, the sessionStorage will be used.

See below a sample of configuration, you can have more information about on oidc client github

const configuration = {
  client_id: 'implicit',
  redirect_uri: 'http://localhost:3000/authentication/callback',
  response_type: 'id_token token',
  post_logout_redirect_uri: 'http://localhost:3000/',
  scope: 'openid profile email',
  authority: 'https://demo.identityserver.io',
  silent_redirect_uri: 'http://localhost:3000/authentication/silent_callback',
  automaticSilentRenew: true,
  loadUserInfo: true,
};

export default configuration;

Polyfill

oidc-client needs some polyfills to works on Internet Explorer. You can use core-js to help you. See Context Sample. In the sample we use some polyfills

import 'core-js/es/array/from';
import 'core-js/es/array/find';
import 'core-js/es/array/includes';
import 'core-js/es/array/find-index';
import 'core-js/es/array/map';

import 'core-js/es/object/assign';

import 'core-js/es/promise';
import 'core-js/es/map';

import 'core-js/es/string/repeat';
import 'core-js/es/string/pad-start';
import 'core-js/es/string/pad-end';
import 'core-js/es/string/starts-with';

import 'whatwg-fetch';

How to consume : Hooks method (Pages/Dashboard/Dashboard.js)

"useReactOidc" returns all props from the Hook :

import React from 'react';
import { useReactOidc } from '@axa-fr/react-oidc-context';

const Dashboard = () => {
  const { oidcUser } = useReactOidc();
  const { profile } = oidcUser;
  return (
    <div>
      <h1>Dashboard</h1>
      <p>Protected Dashboard</p>
      <span>
        Hello {profile.given_name} {profile.family_name}
      </span>
    </div>
  );
};

export default Dashboard;

How to consume : react api context method (Layout/Header.js)

"AuthenticationContext" context contains all props you need

• oidcUser : user information (null if not authenticated)
• logout: logout function
• login: login function
• events: returns events from oidc-client (see oidc client section about events)

import React from 'react';
import { AuthenticationContext } from '@axa-fr/react-oidc-context';
import { Link } from 'react-router-dom';

const headerStyle = {
  display: 'flex',
  backgroundColor: '#26c6da',
  justifyContent: 'space-between',
  padding: 10,
};

const linkStyle = {
  color: 'white',
  textDecoration: 'underline',
};

export default () => (
  <header>
    <AuthenticationContext.Consumer>
      {props => {
        return (
          <div style={headerStyle}>
            <h3>
              <Link style={linkStyle} to="/">
                HOME
              </Link>
            </h3>

            {props.oidcUser ? (
              <ul>
                <li>
                  <Link style={linkStyle} to="/dashboard">
                    Dashboard
                  </Link>
                </li>
                <li>
                  <Link style={linkStyle} to="/admin">
                    Admin
                  </Link>
                </li>
                <button onClick={props.logout}>logout</button>
              </ul>
            ) : (
              <button onClick={props.login}>login</button>
            )}
          </div>
        );
      }}
    </AuthenticationContext.Consumer>
  </header>
);

How to consume : HOC method (Layout/Header.js)

"withOidcUser" function act like "AuthenticationConsumer" below. "OidcSecure" component trigger authentication in case user is not authenticated. So, the children of that component can be accessible only once you are connected.

import React from 'react';
import { withOidcUser, OidcSecure } from '@axa-fr/react-oidc-context';

const Admin = ({ oidcUser }) => (
  <OidcSecure>
    <h1>Admin</h1>
    <p>Protected Admin</p>
    {oidcUser && <p>Bonjour {oidcUser.profile.name}</p>}
  </OidcSecure>
);

// adding the oidc user in the props
export default withOidcUser(Admin);

How to secure a component (Router/Routes.js)

"withOidcSecure" act the same as "OidcSecure" it also trigger authentication in case user is not authenticated.

import React from 'react';
import { Switch, Route } from 'react-router-dom';
import { withOidcSecure } from '@axa-fr/react-oidc-context';
import Home from '../Pages/Home';
import Dashboard from '../Pages/Dashboard';
import Admin from '../Pages/Admin';

const Routes = () => (
  <Switch>
    <Route exact path="/" component={Home} />
    <Route path="/dashboard" component={withOidcSecure(Dashboard)} />
    <Route path="/admin" component={Admin} />
    <Route path="/home" component={Home} />
  </Switch>
);

export default Routes;
