What is msal?

The msal (Microsoft Authentication Library) npm package is used to authenticate users and acquire tokens to access protected resources such as Microsoft Graph, other Microsoft APIs, or your own APIs. It supports various authentication flows and can be used in different environments including single-page applications (SPA), server-side applications, and mobile apps.

What are msal's main functionalities?

User Authentication

This code demonstrates how to configure the msal package for user authentication in a Node.js application. It sets up the client application with the necessary credentials and generates an authorization code URL.

const msal = require('@azure/msal-node');

const config = {
  auth: {
    clientId: 'your_client_id',
    authority: 'https://login.microsoftonline.com/your_tenant_id',
    clientSecret: 'your_client_secret'
  }
};

const cca = new msal.ConfidentialClientApplication(config);

const authCodeUrlParameters = {
  scopes: ['user.read'],
  redirectUri: 'http://localhost:3000/redirect'
};

cca.getAuthCodeUrl(authCodeUrlParameters).then((response) => {
  console.log(response);
}).catch((error) => console.log(JSON.stringify(error)));

Token Acquisition

This code demonstrates how to acquire an access token using an authorization code. The access token can then be used to access protected resources.

const tokenRequest = {
  code: 'auth_code_received_from_auth_code_url',
  scopes: ['user.read'],
  redirectUri: 'http://localhost:3000/redirect'
};

cca.acquireTokenByCode(tokenRequest).then((response) => {
  console.log('Access token:', response.accessToken);
}).catch((error) => console.log(JSON.stringify(error)));

Silent Token Acquisition

This code demonstrates how to silently acquire an access token for a user who is already signed in, without requiring user interaction.

const silentRequest = {
  account: account,
  scopes: ['user.read']
};

cca.acquireTokenSilent(silentRequest).then((response) => {
  console.log('Access token:', response.accessToken);
}).catch((error) => console.log(JSON.stringify(error)));
