In this article we will walk through the code of an example Client participating in an OAuth 2.0, with OpenID Connect, Authorization Code Grant Flow. The Authorization Server in this example is the Google Identity Platform. The example client consists of an Express (Node.js) backend (download) and React frontend (download). This article is inspired by the excellent material found in An Illustrated Guide to OAuth and OpenID Connectby David Neal which I would recommend reading before diving in further here.
