RESTful Routing

Intro

REpresentational State Transfer

REST is a method of mapping between HTTP routes and CRUD

Create Read Update Delete

RESTful routes is a conventional pattern to follow when structuring different routes for interacting with the server whenever an HTTP request is made by the client.

RESTful Routes

There are 7 restful routes

Name	Path	HTTP Verb	Purpose	Mongoose Method
Index	/dogs	GET	List all dogs	Dog.find()
New	/dogs/new	GET	Show new dog form	n/a
Create	/dogs	POST	Create a new dog, then redirect somewhere	Dog.create()
Show	/dogs/:id	GET	Show info about one specific dog	Dog.findById()
Edit	/dogs/:id/edit	GET	Show edit form for one dog	Dog.findById()
Update	/dogs/:id	PUT	Update particular dog, then redirect somewhere	Dog.findByIdAndUpdate()
Destroy	/dogs/:id	DELETE	Delete a particular dog, then redirect somewhere	Dog.findByIdAndRemove()

Why do we use RESTful Routes?

REST is merely a convention. It is not at all technically necessary when creating your application routes. However like many conventions, it is useful because it makes your application predictable, which is useful for any other developers who may be working on it in the future. Much like semantic variables.

Nested Routes

In many cases our routes will need to be nested. For example if we need comments to be associated with a specific blog post, we need to specify the ID of the blog post in the route.

NEW blogs/:id/comments/new GET

CREATE blogs/:id/comments POST

Comments
