We are an early stage SaaS company with UI in React and services in Node JS. We have been asked by one of our customers to become an SAML identity provider. It would be an IDP initiated SSO and we would be the IDP. openEDX would be the Service Provider. We have tried to look for literature and sample code in React or Node but haven't found a clear documentation anywhere. Could someone please point to a literature or a library that we should refer to?
We have tried samlify.js and tried to create an endpoint in our react app. We have written a provider xml. We are however stuck at how to generate response xml and how to send it to the service provider. Would it be a response redirect or how else?
