So I'm using Auth0 for my user sign up. I'm trying to get the user id under sub:value
to add to my database to identify with the post of a user. I'm trying to use a Context API in order to get the user info to put in my database.
react-auth0-spa.js
// src/react-auth0-spa.js
import React, { useState, useEffect, useContext } from "react";
import createAuth0Client from "@auth0/auth0-spa-js";
const DEFAULT_REDIRECT_CALLBACK = () =>
window.history.replaceState({}, document.title, window.location.pathname);
export const Auth0Context = React.createContext();
export const useAuth0 = () => useContext(Auth0Context);
export const Auth0Provider = ({
children,
onRedirectCallback = DEFAULT_REDIRECT_CALLBACK,
...initOptions
}) => {
const [isAuthenticated, setIsAuthenticated] = useState();
const [user, setUser] = useState();
const [auth0Client, setAuth0] = useState();
const [loading, setLoading] = useState(true);
const [popupOpen, setPopupOpen] = useState(false);
useEffect(() => {
const initAuth0 = async () => {
const auth0FromHook = await createAuth0Client(initOptions);
setAuth0(auth0FromHook);
if (window.location.search.includes("code=") &&
window.location.search.includes("state=")) {
const { appState } = await auth0FromHook.handleRedirectCallback();
onRedirectCallback(appState);
}
const isAuthenticated = await auth0FromHook.isAuthenticated();
setIsAuthenticated(isAuthenticated);
if (isAuthenticated) {
const user = await auth0FromHook.getUser();
setUser(user);
}
setLoading(false);
};
initAuth0();
// eslint-disable-next-line
}, []);
const loginWithPopup = async (params = {}) => {
setPopupOpen(true);
try {
await auth0Client.loginWithPopup(params);
} catch (error) {
console.error(error);
} finally {
setPopupOpen(false);
}
const user = await auth0Client.getUser();
setUser(user);
setIsAuthenticated(true);
};
const handleRedirectCallback = async () => {
setLoading(true);
await auth0Client.handleRedirectCallback();
const user = await auth0Client.getUser();
setLoading(false);
setIsAuthenticated(true);
setUser(user);
};
return (
<Auth0Context.Provider
value={{
isAuthenticated,
user,
loading,
popupOpen,
loginWithPopup,
handleRedirectCallback,
getIdTokenClaims: (...p) => auth0Client.getIdTokenClaims(...p),
loginWithRedirect: (...p) => auth0Client.loginWithRedirect(...p),
getTokenSilently: (...p) => auth0Client.getTokenSilently(...p),
getTokenWithPopup: (...p) => auth0Client.getTokenWithPopup(...p),
logout: (...p) => auth0Client.logout(...p)
}}
>
{children}
</Auth0Context.Provider>
);
};
other.js (trying to get user info from react-auth0-spa.js)
class AddAlbum extends Component {
constructor(props) {
super(props);
}
componentDidMount() {
let value = this.context;
console.log(value);
}
render() {
return (
)
}
AddAlbum.contextType = Auth0Context;
This gives me user: undefined
In my index.js I have this
ReactDOM.render(
<Auth0Provider
domain={config.domain}
client_id={config.clientId}
redirect_uri={window.location.origin}
onRedirectCallback={onRedirectCallback}
>
<App />
</Auth0Provider>,
document.getElementById("root")
);
Which I believe is giving me these results:
So I'm wondering why my Context API isn't working and giving me user: undefined
.

You're logging the user when the component first mounts, which is long before the await auth0FromHook.getUser() call will complete. Log it in a componentDidUpdate
, or check in a parent if that value is available, and don't mount the child component until it is.
