无法让PUT在Nodejs / express上工作

I've been writing my first node app, a rest api. I've got everything working pretty good but the PUT won't ever go through. I've tried lots of different combinations, lots of older tutorials and some new ones, and i'm probably pretty close I'm just not sure exactly how to update the record. Also, if you see anything that jumps out at you please feel free to let me know! I'm really liking node so I'd love to learn best practices.I've been writing my first node app, a rest api
