Uses bundling and polyfills to adapt the Node.js MSAL library to Deno, so it could introduce some edge case issues. This is mostly temporary; the official MSAL repo indicated that official Deno support would come after the Node.js version's major release.
See the documentation for the Node.js version below, the interface should be the same.

MSAL Node enables applications to authenticate users using Azure AD work and school accounts (AAD), Microsoft personal accounts (MSA) and social identity providers like Facebook, Google, LinkedIn, Microsoft accounts, etc. through Azure AD B2C service. It also enables your app to get tokens to access Microsoft Cloud services such as Microsoft Graph.
The current version supports the following ways of acquiring tokens:
- Authorization Code Grant with PKCE
- Device Code Grant
- Refresh Token Grant
- Silent Flow
- Username and Password flow
- Authorization Code Grant with a client credential
- Refresh Token Grant
- Silent Flow
- Client Credential Grant
- On-behalf-of flow
- Username and Password flow
[Coming Soon] In the future we plan to add support for:
More details on different grant types supported by Microsoft authentication libraries in general can be found here.
The scenarios supported with this library are:
- Desktop app that calls web APIs
- Web app that calls web APIs
- Web APIs that call web APIs
- Daemon apps
More details on scenarios and the authentication flows that map to each of them can be found here.
See here.
Before using @azure/msal-node you will need to register your app in the azure portal:
npm install @azure/msal-nodeMSAL Node will follow the Long Term Support (LTS) schedule of the Node.js project. Our support plan is as follows.
Any major MSAL Node release:
- Will support stable (even-numbered) Maintenance LTS, Active LTS, and Current versions of Node
- Will drop support for any previously supported Node versions that have reached end of life
- Will not support prerelease/preview/pending versions until they are stable
| MSAL Node version | MSAL support status | Supported Node versions |
|---|---|---|
| 1.x.x | Active development | 10, 12, 14, 16 |
- Understand difference in between Public Client and Confidential Clients
- Initialize a Public Client Application
- Initialize a Confidential Client Application

There are multiple samples included in the repository that use MSAL Node to acquire tokens. These samples are currently used for manual testing, and are not meant to be a reference of best practices, therefore use judgement and do not blindly copy this code to any production applications.
AAD samples:
- auth-code: Express app using OAuth2.0 authorization code flow.
- auth-code-pkce: Express app using OAuth2.0 authorization code flow with PKCE.
- device-code: Command line app using OAuth 2.0 device code flow.
- refresh-token: Command line app using OAuth 2.0 refresh flow.
- silent-flow: Express app using OAuth2.0 authorization code flow to acquire a token and store in the token cache, and silent flow to use tokens in the token cache.
- client-credentials: Daemon app using OAuth 2.0 client credential grant to acquire a token.
- on-behalf-of: Web application using OAuth 2.0 auth code flow to acquire a token for a web API. The web API validates the token, and calls Microsoft Graph on behalf of the user who authenticated in the web application.
- username-password: Web application using OAuth 2.0 resource owner password credentials (ROPC) flow to acquire a token for a web API.
- ElectronTestApp: Electron desktop application using OAuth 2.0 auth code with PKCE flow to acquire a token for a web API such as Microsoft Graph.
B2C samples:
- b2c-auth-code: Express app using OAuth2.0 authorization code flow.
- b2c-auth-code-pkce: Express app using OAuth2.0 authorization code flow with PKCE.
- b2c-silent-flow: Express app using OAuth2.0 authorization code flow to acquire a token and store in the token cache, and silent flow to use tokens in the token cache.
Others:
- msal-node-extensions: Uses authorization code flow to acquire tokens and the msal-extensions library to write the MSAL in-memory token cache to disk.

npm run buildBelow is a list of commands you will probably find useful:
Runs the project in development/watch mode. Your project will be rebuilt upon changes. TSDX has a special logger for you convenience. Error messages are pretty printed and formatted for compatibility VS Code's Problems tab. The library will be rebuilt if you make edits.
Bundles the package to the dist folder.
The package is optimized and bundled with Rollup into multiple formats (CommonJS, UMD, and ES Module).
If you are running the project in development/watch mode, or have made changes in msal-common and need them reflecting across the project, please run lerna bootstrap to link all the symbols. Please note that npm install will unlink all the code, hence it is advised to run lerna bootstrap post installation.
Runs eslint with Prettier
Runs the test watcher (Jest) in an interactive mode. By default, runs tests related to files changed since the last commit. Generate code coverage by adding the flag --coverage. No additional setup needed. Jest can collect code coverage information from entire projects, including untested files.
