A distributed library-management app

*api-gateway - typescript nodejs - all request goes through this - and it's resposible for orchestrating authentication and authorization

*user-auth - typescript nodejs - user-auth service maintains users and authentication and authorization

*book - golang - book service maintains books and authors

*library - golang - library service maintains book loans

Request flow => client -> api-gateway -> user-auth(authentication & authorization)

-> proxy to other service (with appropriate authorization information)
