API Call to Ensure Unique URL (Ep 24) - Build an Advanced Blog/CMS 

Today we are going to build an API Endpoint to test if our blogpost slug is unqiue. We want it to return true if it is unique (indicating we can use it in our post), and false if we can not use it because the slug is already taken by another post.
In our Vue.js component we are going to refactor it so that only set the slug by using a setter method. THis allows us to only write our API call once, and validate it in our setter method. This simplifies the code significantly and makes it easier to maintain.
