Learn how to configure the code for your single-page application (SPA).

Microsoft libraries supporting single-page apps

The following Microsoft libraries support single-page apps:

Application code configuration

In an MSAL library, the application registration information is passed as configuration during the library initialization.

JavaScript (MSAL.js v2)

import * as Msal from "@azure/msal-browser"; // if using CDN, 'Msal' will be available in global scope

// Configuration object constructed.
const config = {
    auth: {
        clientId: 'your_client_id'
    }
};

// create PublicClientApplication instance
const publicClientApplication = new Msal.PublicClientApplication(config);

For more information on the configurable options, see Initializing application with MSAL.js.

JavaScript (MSAL.js v1)

import * as Msal from "msal"; // if using CDN, 'Msal' will be available in global scope

// Configuration object constructed.
const config = {
    auth: {
        clientId: 'your_client_id'
    }
};

// create UserAgentApplication instance
const userAgentApplication = new Msal.UserAgentApplication(config);

For more information on the configurable options, see Initializing application with MSAL.js.

Angular (MSAL.js v2)

// In app.module.ts
import { MsalModule } from '@azure/msal-angular';
import { PublicClientApplication } from '@azure/msal-browser';

@NgModule({
    imports: [
        MsalModule.forRoot( new PublicClientApplication({
            auth: {
                clientId: 'Enter_the_Application_Id_Here',
            }
        }), null, null)
    ]
})
export class AppModule { }

Angular (MSAL.js v1)

// App.module.ts
import { MsalModule } from '@azure/msal-angular';
@NgModule({
    imports: [
        MsalModule.forRoot({
            auth: {
                clientId: 'your_app_id'
            }
        })
    ]
})
export class AppModule { }

React

import { PublicClientApplication } from "@azure/msal-browser";
import { MsalProvider } from "@azure/msal-react";

// Configuration object constructed.
const config = {
    auth: {
        clientId: 'your_client_id'
    }
};

// create PublicClientApplication instance
const publicClientApplication = new PublicClientApplication(config);

// Wrap your app component tree in the MsalProvider component
ReactDOM.render(
    <React.StrictMode>
        <MsalProvider instance={publicClientApplication}>
            <App />
        </ MsalProvider>
    </React.StrictMode>,
    document.getElementById('root')
);
