Tutorial: Enable your Angular single-page application to sign-in users and call APIs with the Microsoft identity platform

The Microsoft identity platform, along with Azure Active Directory (Azure AD) and Azure Azure Active Directory B2C (Azure AD B2C) are central to the Azure cloud ecosystem. This tutorial aims to take you through the fundamentals of modern authentication with Angular, using the Microsoft Authentication Library for Angular (MSAL Angular).

We recommend following the chapters in successive order. However, the code samples are self-contained, so feel free to pick samples by topics that you may need at the moment.

Prerequisites

• Node.js v14 LTS or later
• Dotnet Core SDK v6 or later
• Visual Studio Code
• VS Code Azure Tools Extension
• A modern web browser

Please refer to each sample's README for sample-specific prerequisites.

Recommendations

• jwt.ms for inspecting your tokens
• Fiddler for monitoring your network activity and troubleshooting
• Check MSAL.js FAQ and MSAL Angular FAQ for your questions
• Follow the Azure AD Blog to stay up-to-date with the latest developments

Please refer to each sample's README for sample-specific recommendations.

Alternatively, choose below the sample you want to review.

Chapter 1: Sign-in a user to your application

	Sign-in with Azure AD Sign-in your users with the Azure AD and learn to work with ID Tokens. Learn how single sign-on (SSO) works. Learn to secure your apps to operate in national clouds.
	Sign-in with Azure AD B2C Sign-in your customers with Azure AD B2C. Learn to integrate with external social identity providers. Learn how to use user-flows and custom policies.

Chapter 2: Sign-in a user and get an Access Token for Microsoft Graph

	Get an Access Token from Azure AD and call Microsoft Graph Authenticate your users and acquire an Access Token for Microsoft Graph and then call the Microsoft Graph API. Learn how to handle continuous access evaluation (CAE) events.

Chapter 3: Protect an API and call the API from your client app

	Protect and call a web API on Azure AD Protect your web API with the Azure AD. Use a client application to sign-in a user, acquire an Access Token for your web API and call your protected Web API.
	Protect and call a web API on Azure AD B2C Protect your web API with Azure AD B2C. Use a client application to sign-in a user, acquire an Access Token for your web API and call your protected web API.

Chapter 4: Deploy your applications to Azure

	Deploy to Azure Storage and App Service Prepare your app for deployment to various Azure services. Learn how to package and upload files, configure authentication parameters and use Azure services for managing your operations.

Chapter 5: Control access to your protected API using App Roles and Security Groups

	Call a web API using App Roles Define App Roles and use roles claim in an ID Token to implement Role-based Access Control (RBAC) for your protected web API.
	Call a web API using Security Groups Create Security Groups and use groups claim in an ID Token to implement Role-based Access Control (RBAC) for your protected web API. Handle overage scenarios.

Chapter 6: Dive into advanced scenarios

	Call Microsoft Graph using on-behalf-of flow Use OAuth 2.0 on-behalf-of flow to call Microsoft Graph from your client app via a .NET Core web API. Understand combined consent and .default scope. Learn how to handle continuous access evaluation (CAE) events in downstream APIs
	Call a multi-tenant web API from any tenant Develop and provision a multi-tenant SaaS application. Handle provisioning your app to other tenants and control who can access your resources.
