About

The MSAL library for JavaScript enables client-side JavaScript 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 @azure/msal-react package described by the code in this folder uses the @azure/msal-browser package as a peer dependency to enable authentication in Javascript Single-Page Applications without backend servers. This version of the library uses the OAuth 2.0 Authorization Code Flow with PKCE. To read more about this protocol, as well as the differences between implicit flow and authorization code flow, see the section in the @azure/msal-browser readme.

Prerequisites

• @azure/msal-react is meant to be used in Single-Page Application scenarios.

• Before using @azure/msal-react you will need to register a Single Page Application in Azure AD to get a valid clientId for configuration, and to register the routes that your app will accept redirect traffic on.

Version Support

| MSAL React version | MSAL support status | Supported React versions | | ------------------ | ------------------- | -------------------------- | | MSAL React v2 | Active development | 16, 17, 18 | | MSAL React v1 | In maintenance | 16, 17, 18 |

Note: There have been no functional changes in the MSAL React v2 release.

Installation

The MSAL React package is available on NPM.

npm install react react-dom
npm install @azure/msal-react @azure/msal-browser

Build and Test

See the contributing.md file for more information.

Building the package locally

To build the @azure/msal-react library, you can do the following:

// Install dev dependencies from root of repo
npm install
// Change to the msal-react package directory
cd lib/msal-react/
// To run build only for react package
npm run build

To build both the @azure/msal-react library and @azure/msal-browser libraries, you can do the following:

// Install dev dependencies from root of repo
npm install
// Change to the msal-react package directory
cd lib/msal-react/
// To run build for react and browser packages
npm run build:all

Running Tests

@azure/msal-react uses jest to run unit tests and coverage.

// To run tests
npm test
// To run tests with code coverage
npm run test:coverage
