# react-oidc-context [![Stable Release](https://img.shields.io/npm/v/react-oidc-context.svg)](https://npm.im/react-oidc-context) [![CI](https://github.com/authts/react-oidc-context/actions/workflows/ci.yml/badge.svg)](https://github.com/authts/react-oidc-context/actions/workflows/ci.yml) [![Codecov](https://img.shields.io/codecov/c/github/authts/react-oidc-context)](https://app.codecov.io/gh/authts/react-oidc-context) Lightweight auth library using the [oidc-client-ts](https://github.com/authts/oidc-client-ts) library for React single page applications (SPA). Support for [hooks](https://reactjs.org/docs/hooks-intro.html) and [higher-order components (HOC)](https://reactjs.org/docs/higher-order-components.html). ## Table of Contents - [Documentation](#documentation) - [Installation](#installation) - [Getting Started](#getting-started) - [Contributing](#contributing) - [Influences](#influences) - [License](#license) ## Documentation This library implements an auth context provider by making use of the `oidc-client-ts` library. Its configuration is tight coupled to that library. - [oidc-client-ts](https://github.com/authts/oidc-client-ts) The [`User`](https://authts.github.io/oidc-client-ts/classes/User.html) and [`UserManager`](https://authts.github.io/oidc-client-ts/classes/UserManager.html) is hold in this context, which is accessible from the React application. Additionally it intercepts the auth redirects by looking at the query/fragment parameters and acts accordingly. You still need to setup a redirect uri, which must point to your application, but you do not need to create that route. To renew the access token, the [automatic silent renew](https://authts.github.io/oidc-client-ts/interfaces/UserManagerSettings.html#automaticSilentRenew) feature of `oidc-client-ts` can be used. ## Installation Using [npm](https://npmjs.org/) ```bash npm install oidc-client-ts react-oidc-context --save ``` Using [yarn](https://yarnpkg.com/) ```bash yarn add oidc-client-ts react-oidc-context ``` ## Getting Started Configure the library by wrapping your application in `AuthProvider`: ```jsx // src/index.jsx import React from "react"; import ReactDOM from "react-dom"; import { AuthProvider } from "react-oidc-context"; import App from "./App"; const oidcConfig = { authority: "", client_id: "", redirect_uri: "", // ... }; ReactDOM.render( , document.getElementById("app") ); ``` Use the `useAuth` hook in your components to access authentication state (`isLoading`, `isAuthenticated` and `user`) and authentication methods (`signinRedirect`, `removeUser` and `signOutRedirect`): ```jsx // src/App.jsx import React from "react"; import { useAuth } from "react-oidc-context"; function App() { const auth = useAuth(); switch (auth.activeNavigator) { case "signinSilent": return

Signing you in...

; case "signoutRedirect": return

Signing you out...

; } if (auth.isLoading) { return

; } if (auth.error) { return

Oops... {auth.error.kind} caused {auth.error.message}

; } if (auth.isAuthenticated) { return (

Hello {auth.user?.profile.sub}{" "}

); } return ; } export default App; ``` You **must** provide an implementation of `onSigninCallback` to `oidcConfig` to remove the payload from the URL upon successful login. Otherwise if you refresh the page and the payload is still there, `signinSilent` - which handles renewing your token - won't work. A working implementation is already in the code [here](https://github.com/authts/react-oidc-context/blob/f175dcba6ab09871b027d6a2f2224a17712b67c5/src/AuthProvider.tsx#L20-L30). ### Use with a Class Component Use the `withAuth` higher-order component to add the `auth` property to class components: ```jsx // src/Profile.jsx import React from "react"; import { withAuth } from "react-oidc-context"; class Profile extends React.Component { render() { // `this.props.auth` has all the same properties as the `useAuth` hook const auth = this.props.auth; return

Hello {auth.user?.profile.sub}

; } } export default withAuth(Profile); ``` ### Call a protected API As a child of `AuthProvider` with a user containing an access token: ```jsx // src/Posts.jsx import React from "react"; import { useAuth } from "react-oidc-context"; const Posts = () => { const auth = useAuth(); const [posts, setPosts] = React.useState(Array); React.useEffect(() => { (async () => { try { const token = auth.user?.access_token; const response = await fetch("https://api.example.com/posts", { headers: { Authorization: `Bearer ${token}`, }, }); setPosts(await response.json()); } catch (e) { console.error(e); } })(); }, [auth]); if (!posts.length) { return

; } return (

{post}

); }; export default Posts; ``` As **not** a child of `AuthProvider` (e.g. redux slice) when using local storage (`WebStorageStateStore`) for the user containing an access token: ```jsx // src/slice.js import { User } from "oidc-client-ts" function getUser() { const oidcStorage = localStorage.getItem(`oidc.user::`) if (!oidcStorage) { return null; } return User.fromStorageString(oidcStorage); } export const getPosts = createAsyncThunk( "store/getPosts", async () => { const user = getUser(); const token = user?.access_token; return fetch("https://api.example.com/posts", { headers: { Authorization: `Bearer ${token}`, }, }); }, // ... ) ``` ### Protect a route Secure a route component by using the `withAuthenticationRequired` higher-order component. If a user attempts to access this route without authentication, they will be redirected to the login page. ```jsx import React from 'react'; import { withAuthenticationRequired } from "react-oidc-context"; const PrivateRoute = () => (

Private

); export default withAuthenticationRequired(PrivateRoute, { OnRedirecting: () => (

Redirecting to the login page...

) }); ``` ### Adding event listeners The underlying [`UserManagerEvents`](https://authts.github.io/oidc-client-ts/classes/UserManagerEvents.html) instance can be imperatively managed with the `useAuth` hook. ```jsx // src/App.jsx import React from "react"; import { useAuth } from "react-oidc-context"; function App() { const auth = useAuth(); React.useEffect(() => { // the `return` is important - addAccessTokenExpiring() returns a cleanup function return auth.events.addAccessTokenExpiring(() => { if (alert("You're about to be signed out due to inactivity. Press continue to stay signed in.")) { auth.signinSilent(); } }) }, [auth.events, auth.signinSilent]); return ; } export default App; ``` ### Automatic sign-in Automatically sign-in and silently reestablish your previous session, if you close the tab and reopen the application. ```jsx // index.jsx const oidcConfig: AuthProviderProps = { ... userStore: new WebStorageStateStore({ store: window.localStorage }), }; ``` ```jsx // src/App.jsx import React from "react"; import { useAuth, hasAuthParams } from "react-oidc-context"; function App() { const auth = useAuth(); const [hasTriedSignin, setHasTriedSignin] = React.useState(false); // automatically sign-in React.useEffect(() => { if (!hasAuthParams() && !auth.isAuthenticated && !auth.activeNavigator && !auth.isLoading && !hasTriedSignin ) { auth.signinRedirect(); setHasTriedSignin(true); } }, [auth, hasTriedSignin]); if (auth.isLoading) { return

Signing you in/out...

; } if (!auth.isAuthenticated) { return

Unable to log in

; } return ; } export default App; ``` #### useAutoSignin Use the `useAutoSignin` hook inside the AuthProvider to automatically sign in. ```jsx // src/App.jsx import React from "react"; import { useAutoSignin } from "react-oidc-context"; function App() { // If you provide no signinMethod at all, the default is signinRedirect const { isLoading, isAuthenticated, error } = useAutoSignin({signinMethod: "signinRedirect"}); if (isLoading) { return

Signing you in/out...

; } if (!isAuthenticated) { return

Unable to log in

; } if(error) { return

An error occured

} return

Signed in successfully

; } export default App; ``` ## Contributing We appreciate feedback and contribution to this repo! ## Influences This library is inspired by [oidc-react](https://github.com/bjerkio/oidc-react), which lacks error handling and [auth0-react](https://github.com/auth0/auth0-react), which is focused on auth0. ## License This project is licensed under the MIT license.
