Server Application

An ExpressJS Node server was added in the Server folder. Previously, only a dev server was available through webpack which could provision a user and a token. This dev server should not be used when deploying this as a sample application. That is why a new ExpressJS server application was added. In dev mode, the webpack dev server proxies any request to /tokens/provisionUser to the local 8080 port where the Server application is listening.

A top-level package.json has been added to facilitate easy installing of packages, starting dev environment, building, and packaging the Client and Server application.

ARM Templates

To facilitate deployment to Azure, two Bicep files have been added. These files can be transpiled to JSON ARM templates using az bicep build --file <filename>.
Two bicep templates have been added: One to create all resources necessary for deployment (azuredeploy.bicep), and one to create all resources except an Azure Communications Service resource (azuredeploy_existingresource.bicep).
