Lightweight auth library using the oidc-client-ts library for React single page applications (SPA). Support for hooks and higher-order components (HOC).
This library implements an auth context provider by making use of the
oidc-client-ts library. Its configuration is tight coupled to that library.
The
User
and
UserManager
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
feature of oidc-client-ts can be used.
Using npm
npm install oidc-client-ts react-oidc-context --saveUsing yarn
yarn add oidc-client-ts react-oidc-contextConfigure the library by wrapping your application in AuthProvider:
// 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: "<your authority>",
client_id: "<your client id>",
redirect_uri: "<your redirect uri>",
// ...
};
ReactDOM.render(
<AuthProvider {...oidcConfig}>
<App />
</AuthProvider>,
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):
// src/App.jsx
import React from "react";
import { useAuth } from "react-oidc-context";
function App() {
const auth = useAuth();
switch (auth.activeNavigator) {
case "signinSilent":
return <div>Signing you in...</div>;
case "signoutRedirect":
return <div>Signing you out...</div>;
}
if (auth.isLoading) {
return <div>Loading...</div>;
}
if (auth.error) {
return <div>Oops... {auth.error.message}</div>;
}
if (auth.isAuthenticated) {
return (
<div>
Hello {auth.user?.profile.sub}{" "}
<button onClick={() => void auth.removeUser()}>Log out</button>
</div>
);
}
return <button onClick={() => void auth.signinRedirect()}>Log in</button>;
}
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.
Use the withAuth higher-order component to add the auth property to class
components:
// 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 <div>Hello {auth.user?.profile.sub}</div>;
}
}
export default withAuth(Profile);As a child of AuthProvider with a user containing an access token:
// 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 <div>Loading...</div>;
}
return (
<ul>
{posts.map((post, index) => {
return <li key={index}>{post}</li>;
})}
</ul>
);
};
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:
// src/slice.js
import { User } from "oidc-client-ts"
function getUser() {
const oidcStorage = localStorage.getItem(`oidc.user:<your authority>:<your client id>`)
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}`,
},
});
},
// ...
)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.
import React from 'react';
import { withAuthenticationRequired } from "react-oidc-context";
const PrivateRoute = () => (<div>Private</div>);
export default withAuthenticationRequired(PrivateRoute, {
OnRedirecting: () => (<div>Redirecting to the login page...</div>)
});The underlying UserManagerEvents instance can be imperatively managed with the useAuth hook.
// 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 <button onClick={() => void auth.signinRedirect()}>Log in</button>;
}
export default App;Automatically sign-in and silently reestablish your previous session, if you close the tab and reopen the application.
// index.jsx
const oidcConfig: AuthProviderProps = {
...
userStore: new WebStorageStateStore({ store: window.localStorage }),
};// 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 <div>Signing you in/out...</div>;
}
if (!auth.isAuthenticated) {
return <div>Unable to log in</div>;
}
return <button onClick={() => void auth.removeUser()}>Log out</button>;
}
export default App;We appreciate feedback and contribution to this repo!
This library is inspired by oidc-react, which lacks error handling and auth0-react, which is focused on auth0.
