ra-auth-msal

An auth provider for react-admin that handles authentication using the Microsoft Authentication Library (MSAL).

This is useful when using Azure Active Directory to authenticate your users.

This package provides:

- An msalAuthProvider function to get the auth provider
- An msalHttpClient helper to get a fetch-like function that adds the access token to the request
- A custom LoginPage component that displays a loading indicator if the redirection takes too long

Supported MSAL Features

- Sign-in using any authentication flow supported by MSAL for Single Page Apps (Authorization Code and Implicit Grant), with the ability to configure the scopes and optional claims
- Get an access token for the user, with the ability to configure the scopes and optional claims, allowing for instance to query a Microsoft Graph endpoint
- Use the user's roles and groups to compute permissions
- Automatic token refresh

Installation

``sh
yarn add ra-auth-msal


or


npm install --save ra-auth-msal
`

Basic Usage

`jsx
// in src/authConfig.js
export const msalConfig = {
auth: {
// 'Application (client) ID' of app registration in Azure portal - this value is a GUID
clientId: "12345678-1234-1234-1234-123456789012",
// Full directory URL, in the form of https://login.microsoftonline.com/
authority: "https://login.microsoftonline.com/common",
// Full redirect URL, in form of http://localhost:8080/auth-callback
redirectUri: "http://localhost:8080/auth-callback",
// We need to disable this feature because it is already handled by react-admin, and would otherwise conflict
navigateToLoginRequestUrl: false,
},
cache: {
cacheLocation: "sessionStorage",
storeAuthStateInCookie: false,
},
};
`

`jsx
// in src/App.jsx
import React from "react";
import { Admin, Resource } from 'react-admin';
import { BrowserRouter } from "react-router-dom";
import { PublicClientApplication } from "@azure/msal-browser";
import { LoginPage, msalAuthProvider } from "ra-auth-msal";
import dataProvider from './dataProvider';
import posts from './posts';
import { msalConfig } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);
const authProvider = msalAuthProvider({
msalInstance: myMSALObj,
});

const App = () => {
return (

authProvider={authProvider}
dataProvider={dataProvider}
title="Example Admin"
loginPage={LoginPage}
>



);
};
export default App;
`

Tip: You need to wrap your component in a for this library to work. Indeed, MSAL uses a hash-based routing strategy when redirecting back to your app, which is incompatible with a .

You can choose whether the authProvider should redirect to the MS login form when the user is not authenticated. By default, it is set to true.

It can be useful to set it to false when you want to trigger the redirection only from a custom login page.

`jsx
// in src/authConfig.js
export const msalConfig = {
// ...
};
`

`jsx
// in src/CustomLoginPage.jsx
import * as React from "react";
import { Button } from "@mui/material";
import { useLogin } from "react-admin";

/**
* Csutom Login Page used to trigger the redirection to the MS login page.
*/
export const CustomLoginPage = () => {
const login = useLogin();
return (



);
};
`

`jsx
// in src/App.jsx
import React from "react";
import { Admin, Resource } from 'react-admin';
import { BrowserRouter } from "react-router-dom";
import { PublicClientApplication } from "@azure/msal-browser";
import { msalAuthProvider } from "ra-auth-msal";
import { CustomLoginPage } from "./CustomLoginPage";
import dataProvider from './dataProvider';
import posts from './posts';
import { msalConfig } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);
const authProvider = msalAuthProvider({
msalInstance: myMSALObj,
redirectOnCheckAuth: false,
});

const App = () => {
return (

authProvider={authProvider}
dataProvider={dataProvider}
title="Example Admin"
loginPage={CustomLoginPage}
>



);
};
export default App;
`

You can choose whether the authProvider should redirect to the page the user was visiting once the user has been authenticated (this allows easier URL sharing between users). By default, it is set to true.

Note: This features relies on sessionStorage and is not available with Server-Side Rendering.

You can disable this feature like this:

`jsx
// in src/authConfig.js
export const msalConfig = {
// ...
};
`

`jsx
// in src/App.jsx
import React from "react";
import { Admin, Resource } from 'react-admin';
import { BrowserRouter } from "react-router-dom";
import { PublicClientApplication } from "@azure/msal-browser";
import { msalAuthProvider } from "ra-auth-msal";
import { CustomLoginPage } from "./CustomLoginPage";
import dataProvider from './dataProvider';
import posts from './posts';
import { msalConfig } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);
const authProvider = msalAuthProvider({
msalInstance: myMSALObj,
enableDeepLinkRedirect: false,
});

const App = () => {
return (

authProvider={authProvider}
dataProvider={dataProvider}
title="Example Admin"
>



);
};
export default App;
`

ra-auth-msal includes an msalHttpClient that can be used to make authenticated requests to your API. This helper automatically adds the accessToken to the request headers.

Here is an example with ra-data-json-server:

`jsx
// in src/authConfig.js
export const msalConfig = {
// ...
};

/**
* Add here the scopes to request when obtaining an access token for MS Graph API. For more information, see:
* https://github.com/AzureAD/microsoft-authentication-library-for-js/blob/dev/lib/msal-browser/docs/resources-and-scopes.md
*/
export const tokenRequest = {
scopes: ["User.Read"],
forceRefresh: false, // Set this to "true" to skip a cached token and go to the server to get a new token
};
`

`jsx
// in src/App.jsx
import React from "react";
import { Admin, Resource } from 'react-admin';
import { BrowserRouter } from "react-router-dom";
import { PublicClientApplication } from "@azure/msal-browser";
import { LoginPage, msalAuthProvider, msalHttpClient } from "ra-auth-msal";
import jsonServerProvider from "ra-data-json-server";
import posts from './posts';
import { msalConfig, tokenRequest } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);

const authProvider = msalAuthProvider({
msalInstance: myMSALObj,
tokenRequest
});

const httpClient = msalHttpClient({
msalInstance: myMSALObj,
tokenRequest
});

const dataProvider = jsonServerProvider(
"https://jsonplaceholder.typicode.com",
httpClient
);

const App = () => {
return (

authProvider={authProvider}
dataProvider={dataProvider}
title="Example Admin"
loginPage={LoginPage}
>



);
};
export default App;
`

Tip: By default msalHttpClient will use the accessToken. If you want to use the idToken instead, you will need to provide your own httpClient like so:

`js
import { fetchUtils } from "react-admin";

const myHttpClient = ({ msalInstance, tokenRequest }) => async (url, options = {}) => {
const account = msalInstance.getActiveAccount();
const authResult = await msalInstance.acquireTokenSilent({
account,
...tokenRequest,
});
const token = authResult && authResult.idToken;
const user = { authenticated: !!token, token: Bearer ${token} };
return fetchUtils.fetchJson(url, { ...options, user });
};
`

$3

The authProvider already supports automatic refresh of the token. However, if your dataProvider passes the token to your API, you should wrap it with addRefreshAuthToDataProvider to ensure it also refreshes the token when needed:

`js
import { addRefreshAuthToDataProvider } from 'react-admin';
import { msalRefreshAuth } from "ra-auth-msal";
import { PublicClientApplication } from "@azure/msal-browser";
import { msalConfig, tokenRequest } from "./authConfig";
import { dataProvider } from './dataProvider';

const myMSALObj = new PublicClientApplication(msalConfig);

const dataProvider = addRefreshAuthToDataProvider(
dataProvider,
msalRefreshAuth({
msalInstance: myMSALObj,
tokenRequest,
})
);
``
