Tutorial: Enable your Node.js & Express web app to sign-in users and call APIs with the Microsoft identity platform
The Microsoft identity platform, along with Microsoft Entra ID (Microsoft Entra ID) and Azure Active Directory B2C (Azure Active Directory B2C) are central to the Azure cloud ecosystem. This tutorial aims to take you through the fundamentals of modern authentication with Node.js, using the Microsoft Authentication Library for Node.js (MSAL Node).
This tutorial also features a simple wrapper around MSAL Node ConfidentialClientApplication class in order to streamline routine authentication tasks such as login, logout, token acquisition. You can find the wrapper here: msal-node-wrapper. Fork it and customize as you need. Suggestions and contributions are welcome!
⚠️ msal-node-wrapper is for demo purposes only and is not recommended for production applications. If you're looking for using MSAL Node directly in your web app, please refer to:
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.
⚠️ This is a work in progress. Come back frequently to discover more samples.
- Node.js (>= v16.x)
- Express.js (>= v4.x)
- Visual Studio Code
- VS Code Azure Tools Extension
- A modern web browser
Please refer to each chapter's README for sample-specific prerequisites.
- jwt.ms for inspecting your tokens
- Fiddler for monitoring your network activity and troubleshooting
- Check the MSAL Node FAQ for your questions first
- Follow the Microsoft Entra ID Blog to stay up-to-date with the latest developments
Please refer to each chapter's README for sample-specific recommendations.
