USE OIDC

useIDC is a client side SDK that establishes communication between Open ID Connect Identity Server. This library is designed for Web Apps and Node.js applications. useOIDC adheres to PCKE extension to OAuth which facilitates secure authorization code in public clients.

Import useOIDC to an existing project

yarn add @pandolink/utils

or

npm install @pandolink/utils

Update Environment Variables

    REACT_APP_AUTH_SERVER = 'https://login.staging.yourcompany.com'
    REACT_APP_REDIRECT_URI = 'https://yourcompany.com/sample'
    REACT_APP_LOGOUT_ENDPOINT = '/connect/endsession'
    REACT_APP_SCOPE = 'Add_Identity_Server_Scopes_Here'
    REACT_APP_ADMIN_CLIENT_SECRET = 'Add_Client_Secret_Here'
    REACT_APP_ADMIN_CLIENT_ID = 'Add_Client_ID_Here'

How to use the hook?

import { useOIDC } from '@pandolink/utils';
import { Route, Switch, useHistory, useLocation } from 'react-router-dom'

const App: React.FC = () => {
    const navigate = useHistory()
    const location = useLocation()

    const [state, actions, hasTokenExpired] = useOIDC({
        waitForUserAction: true,
    })

    if (!state) return null

    const { isAuthenticated } = state?.context ?? {}

    useEffect(() => {
        if (isAuthenticated && location?.search.includes('code')) {
        navigate.push('/home')
        }
    }, [isAuthenticated])

    const showLandingPage = state.matches?.('wait_for_user_interaction')

    return (
       <SWitch>
          <Route path='*'>
            {isAuthenticated ? (
            <YourHomeComponent />
            ) : showLandingPage ? (
            <YourLandingPage />
            ) : (
            <LoaderComponent />
            )}
          </Route>
       </Switch>
    );

}

Add this to your top level component, react-router-dom is optional. You can still conditionally render your components without this. This is only used in a project that conditionally render components by routes.

The useEffect above is required because after getting the access token, a code is appended to the url. And this effect is executed to remove the appended code from the url.

View flow diagram here

useOIDC performs authorization, authentication and request an access token for your react application.

1: AUTHORIZATION

It will first check if you have an access token. If access token does not exist then it will start the Open Id Connection flow.

2: REDIRECT

Your application will be redirected to the url you provided in the REACT_APP_LOGIN_URI env. If login credentials is correct then you'll be authorize in a code will be return in the url.

3: GET ACCESS TOKEN

To request for an access token, that code will then be taken by useOIDC and use it to authenticate you. If authenticated the Open ID Identity server will return an acceess token.

Use that access token to to request for data from the GRPC server.
