Please see here for supported browsers.
React versions 16 and 17 are supported.
Yes! However, authentication cannot be done server side and you should avoid invoking msal APIs server side. @azure/msal-react abstracts some of this logic away from you but if you are building custom authentication logic please ensure all APIs are invoked when rendered in the browser. You can take a look at our Next.js sample and Gatsby sample for examples.
Yes, @azure/msal-react supports both function and class components. Hooks, however, cannot be used in class components so you will need to consume the msal context and use the APIs provided by @azure/msal-browser to build equivalent logic. More information about using @azure/msal-react in class components can be found here.
Yes, @azure/msal-react can be used as a custom authentication provider for the Microsoft Graph JavaScript SDK. For an implementation, please refer to the sample: React SPA calling Graph API.
If you've used @azure/msal-browser or msal v1 in the past, you may be used to calling handleRedirectCallback or handleRedirectPromise on page load to handle the response of a redirect. In @azure/msal-react this is done under the hood and you do not need to call handleRedirectPromiseon your own. After calling loginRedirect or acquireTokenRedirect you'll be redirected to the AAD sign in page and after entering your credentials you'll be redirected back to your app which should now show that a user is signed in. Since this is a new, clean instance of your application the actual response object cannot be returned to the original loginRedirect API call. Instead there are a few ways you can get what you need:
If you just need an id or access token we recommend calling the acquireTokenSilent API right before you need the token. Be sure to check that a user is signed in and interaction isn't in progress before you attempt to retrieve the token. If the previous redirect operation was successful acquireTokenSilent will return the tokens from the cache.
const GetDataFromAPI = () => {
const { instance, accounts, inProgress } = useMsal();
const isAuthenticated = useIsAuthenticated();
const [graphData, setGraphData] = useState(null);
useEffect(() => {
if (isAuthenticated && inProgress === InteractionStatus.None) {
instance.acquireTokenSilent({
account: accounts[0],
scopes: ["User.Read"]
}).then(response => {
callAPI(response.accessToken);
})
}
}, [inProgress, isAuthenticated, accounts, instance]);
};If you need direct access to the response object or error returned by a redirect operation there are 3 ways you can do this:
- Use the event API to register a callback that will be invoked with the response when you return to your app. Make sure this is registered in a code path that is run after the redirect as any callbacks registered before the redirect will be lost.
- Use the useMsalAuthentication hook to login. This hook will return the result or error when you are returned to your app.
- Call
handleRedirectPromisewhich will resolve with the result or reject with an error if the page was loaded as a result of a redirect.
The short answer is that all components in your app that need access to msal APIs should be rendered underneath an MsalProvider component ensuring your components have access to the msal context. However, there may be scenarios where it makes more sense to have a utility function outside your component tree to handle acquiring access tokens or determine whether or not a user is signed in. This is fine to do as long as you are not calling APIs that may change the user's logged in state or trigger interaction.
This means the following APIs are off-limits outside the context of MsalProvider:
loginPopuploginRedirecthandleRedirectPromisessoSilentlogoutacquireTokenPopupacquireTokenRedirect
Note: If you do choose to use any other @azure/msal-browser API outside of the react context you should still use the same PublicClientApplication instance you pass into MsalProvider.
MSAL React supports self-service sign-up in the auth code flow. Please see our docs here for supported prompt values in the request and their expected outcomes, and here for an overview of self-service sign-up and configuration changes that need to be made to your Azure tenant. Please note that that self-service sign-up is not available in B2C and test environments.
The new password reset experience is now part of the sign-up or sign-in policy. When the user selects the Forgot your password? link, they are immediately sent to the Forgot Password experience. You don't need a separate policy for password reset anymore.
Our recommendation is to move to the new password reset experience since it simplifies the app state and reduces error handling on the user-end. If for some reason you have to use the legacy forgot password flow, you'll have to handle the AADB2C90118 error response returned from B2C service when a user selects the Forgot your password? link, and call login again with your forgot password policy.
If you're using the useMsalAuthentication hook to login you can inspect the error returned and invoke the login callback with a new request object.
function Example() {
const { result, error, login } = useMsalAuthentication(InteractionType.Popup);
useEffect(() => {
if (error && error.errorMessage.indexOf("AADB2C90118") > -1) {
const request = {
authority: "your-b2c-authority/your-password-reset-policy"
}
login(InteractionType.Popup, request)
}
}, [error]);
}If you're using the MsalAuthenticationTemplate or you're calling one of the login APIs directly you should use the event API to catch the error and handle it.
function Example() {
const { instance } = useMsal();
useEffect(() => {
const callbackId = instance.addEventCallback((event) => {
if (event.eventType === EventType.LOGIN_FAILURE) {
if (event.error && event.error.errorMessage.indexOf("AADB2C90118") > -1) {
if (event.interactionType === InteractionType.Redirect) {
instance.loginRedirect(forgotPasswordRequest);
} else if (event.interactionType === InteractionType.Popup) {
instance.loginPopup(forgotPasswordRequest).catch(e => {
return;
});
}
}
}
});
return () => {
if (callbackId) {
instance.removeEventCallback(callbackId);
}
};
}, []);
