ra-auth-msal

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

Installation

yarn add ra-auth-msal
# or
npm install --save ra-auth-msal

Basic Usage

// 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/<tenant-id>
    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,
  },
};

// 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 App = () => {
  const authProvider = msalAuthProvider({
    msalInstance: myMSALObj,
  });

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

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

Advanced Usage

Handling Permissions

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

/**
 * Customize this map to match your own roles and permissions
 */
const rolesPermissionMap = {
  "12345678-1234-1234-1234-123456789012": "user",
  "12345678-1234-1234-1234-123456789013": "admin",
};

/**
 * Custom function to map roles to permissions, using the rolesPermissionMap above.
 * Alternatively, you can use the MS Graph API to get more information about the user's roles and groups.
 */
export const getPermissionsFromAccount = async (account) => {
  const roles = account?.idTokenClaims?.roles ?? [];
  return roles.map((role) => rolesPermissionMap[role]);
};

// 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, getPermissionsFromAccount } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);

const App = () => {
  const authProvider = msalAuthProvider({
    msalInstance: myMSALObj,
    getPermissionsFromAccount,
  });

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

Handling User Identity

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

/**
 * Custom function to get the identity from the account info.
 */
export const getIdentityFromAccount = async (account) => {
  return {
    id: account?.localAccountId,
    fullName: account?.username,
  };
};

// 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, getIdentityFromAccount } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);

const App = () => {
  const authProvider = msalAuthProvider({
    msalInstance: myMSALObj,
    getIdentityFromAccount,
  });

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

Custom Login Request

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

/**
 * Scopes you add here will be prompted for user consent during sign-in.
 * By default, MSAL.js will add OIDC scopes (openid, profile, email) to any login request.
 * For more information about OIDC scopes, visit:
 * https://docs.microsoft.com/en-us/azure/active-directory/develop/v2-permissions-and-consent#openid-connect-scopes
 */
export const loginRequest = {
  scopes: ["User.Read"],
};

// 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, loginRequest } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);

const App = () => {
  const authProvider = msalAuthProvider({
    msalInstance: myMSALObj,
    loginRequest,
  });

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

Custom Token Request

// 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
};

// 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, tokenRequest } from "./authConfig";

const myMSALObj = new PublicClientApplication(msalConfig);

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

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

redirectOnCheckAuth

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.

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

// 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 (
    <div>
      <Button onClick={() => login({})}>
          Sign in with Microsoft
      </Button>
    </div>
  );
};

// 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 App = () => {
  const authProvider = msalAuthProvider({
    msalInstance: myMSALObj,
    redirectOnCheckAuth: false,
  });

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={CustomLoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
};
export default App;

msalHttpClient

// 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
};

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

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

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

  return (
    <BrowserRouter>
       <Admin
           authProvider={authProvider}
           dataProvider={dataProvider}
           title="Example Admin"
           loginPage={LoginPage}
        >
            <Resource name="posts" {...posts} />
      </Admin>
    </BrowserRouter>
   );
