The Getting Started tutorial for Node.js uses this sample application to provide you with a sample workflow for working with any Node.js app on IBM Cloud or in IBM Cloud Private; you set up a development environment, deploy an app locally and on the cloud, and then integrate a IBM Cloud database service in your app.
The Node.js app uses Express Framework and Cloudant noSQL DB service to add information to a database and then return information from a database to the UI. To learn more about how the app connects to Cloudant, see the Cloudant library for Node.js.
This sample has been extended to work with the App ID service to authenticate a user session using either a cloud directory or social id. If a Cloudant database has been bound to the application, after authentication, the user's name will be added to the database.
The withRedis branch of this repository shows how to add the Redis Cloud service to the application to persist express-session state in an external store allowing the application to be horizontally scaled when using App ID.
