RESTful API From Scratch Using Node, Express and MongoDB

description
In this video we will create a full RESTful web api that will allow us to get, post, put and delete JSON data through HTTP requests. It is long but it is from absolute scratch front to back. No copy and paste and no generators, etc Second part with Angular frontend - https://www.youtube.com/watch?v=qrIvv6OTN2Y&feature=youtu.be SOURCE FILES - https://github.com/bradtraversy/bookstore VISIT MY WEBISTE: Check Out My Udemy Courses http://www.traversymedia.com
