A minimal web client (served by http-server) interacts with a simple backend node server via a GET and POST

This code implements a simple Angular2 (beta) application that resides on an http-server and features a single page containing two buttons that issue GET and POST requests to a backend node server.

localhost: web-client on web-server (8080)
localhost: api/backend server on node server (8081)

Content/data on the web-client (frontend) is obtained via calls to the backend node server. Unfortunately, javascript is quite strict (or fortunately) with cross origin (and same origin) requests (CORs). CORs authorise certain servers to interact (with the backend).

This sordid tale requires a change in the web server that we will use to serve the web application (we are using the http-server in this case), and that we enable the backend to accept access from any server (this is in a dev environment, so it is not too serious just yet).

• We need to install an http server:

  npm install -g http-server

• Install the packages in packages.json with

  npm install

• Start the node server

  node server.js

• Finally, start the http-server

  npm start
