Easy Auth JS

A pure JavaScript/TypeScript library that allows browser based applications running on Azure App Service to fetch claims information about the authenticated user.

Why?

Libraries like Microsoft's Auth Library require that the entire application runtime be downloaded prior to performing the authentication flow, usually using a Public Client Authorization Code flow with (PKCE) exchange.

App Service has a much better way of performing authentication: offload it to built in middleware, dubbed "Azure Easy Auth". Azure Easy Auth acts as an application middleware included by default in Azure App Service, and configured in the "Authentication" tab in the Azure portal.

The Azure Easy Auth middleware adds several endpoints to your application under the /.auth/** path. It supports popular identity providers like Azure Active Directory and Okta, and can work with any OpenID Connect compliant browser.

Azure Easy Auth allows you to offload all authentication to the middlware, letting you focus on your business logic.

This library allows applications deployed behind Azure Easy Auth to interface with the endpoints provided by Azure App Service.
