contrib-npm node example - UK Postcode geo lookup

Simple node-red-contrib-npm example

Uses the node-red-contrib-npm - - node that can wrap simple npm modules automatically.

Note: You must install the node-red-contrib-npm before this example will work. Either via the Menu - palette manager or

cd ~/.node-red
npm i node-red-contrib-npm
