The Microsoft Authentication Library for JavaScript enables both client-side and server-side JavaScript applications to authenticate users using Azure AD for 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 lib folder contains the source code for our libraries in active development. You will also find all the details about installing the libraries in their respective README.md.
