Built and tested with:

• Ubuntu 18.04
• Node v8.12.0
• NPM 6.4.1
• Firefox 63.0 (64-bit)
• Chromium Version 70.0.3538.77

Both API and static server running on Localhost, ports 3000 and 3001.

mkdir <yourdir>
cd <yourdir>
git clone https://github.com/citkane/eefronted ./
npm install

cd <yourdir>
npm start

This will start both the API server and the web server at ports 3000 and 3001 respectively.

Browse to http://localhost:3001 to view the frontend.

I have not packaged or minified the project, so please use the above method on localhost for serving as it resolves issues with resource locations and CORS.

It includes a modification to the provided API app.js script: res.header("Access-Control-Allow-Methods", "*, PUT");

Without explicit declaration of PUT my Firefox (not Chromium) was rejecting PUT requests as invalid method for CORS (GET was working fine).
