npm dependencies and devDependencies

Currently I'm working through an app that has been abandoned by the developers.  The client was getting no response from the dev company, when they asked if I could have a look.  The app hadn't been updated for 18 months.  So of course, a product that hasn't been updated in that timeframe is going to have a suite of npm update issues / conflicts.
