By this point, if you've read chapter 3 of this book, it should be obvious that we will only be supporting JSON in our API. Not only does GitHub and various other companies only support JSON, it would also create additional and unnecessary work for us if we were to support another format like XML ourselves. Hence, we will no JSON, yay!
As stated previously, we will be picking the most simple API versioning strategy and we will be going with the URI prefixing method of putting api/v1 in our routes.
As mentioned in chapter 3 of Representational Design, we should be following a .
In chapter 2 of , we stated that we will pragmatic with our approach as opposed to dogmatic. This means that we will not be purists and adhere to all of the guidelines that make our API RESTful. This means we will NOT be creating a hypermedia-friendly REST API, but if you want to do so, you may check out the .
Fielding stated in his dissertation that using cookies actually "violates REST". Again, we are trying to be pragmatic, so we will be using cookie-based authentication in our application, you may use other forms of authentication, but for the purpose of this book, we will be using cookies.
As a general precaution, we will be applying as much of the guidelines from chapter 3, but we will not be enforcing every single guideline. Keep in mind that:
Guidelines provide a shared language to promote consistency among multiple people in terminology usage. It is simply a set of recommendations that are there to create reliability and consistencies among a group of individuals.

If you recall, in JavaScript/Node.js land, structure has become a big problem in our community. However, there are a ton of pre-made boilerplate starter kits available for our needs.
You can find a list of them here in this article:
We will be using my own custom setup, but feel free to change it up to your own accord, or pull in anything else as you see fit.
A good example of this is from chapter 3, . Why? Because it would be an overkill to submit your custom vendor data type to , because even a company such as GitHub has yet to be approved of their custom vendor data type.
These "Express Boilerplates" provide a nice foundation for starting a project in the right way. The best boilerplate start that I have seen is . It provides a bunch of pre-configured out-of-the-box features already baked into the repository. Features such as a global error handler, a validation library, a good authentication and authorization starter kit, and many more.
