Restful Routes & CRUD

Warmup

• What does CRUD stand for?
• Look at your Task Manager controller: what are the eight different method/argument combinations contained there?
• What does each one do?

Vocab

• CRUD
• Resource
• REST
• HTTP Verbs
• URI
• 7 RESTful Routes

CRUD

• C - Create
• R - Read
• U - Update
• D - Delete

Resource

• Generic term for something that we have in our application (e.g. tasks, people, movies).
• Tables hold instances of resources
• Often, our applications will have a separate controller and model for each resource.

REST

• Representational State Transfer (ReST) is a web architecture style
• Coined by Roy Fielding in doctoral dissertation (2000)
• A map between HTTP verb/path combinations and CRUD actions users want to perform on a resource

HTTP Verbs

• GET: retrieve a resource from a url
• POST: create a new resource
• PUT: update an entire resource
• PATCH: update part of a resource
• DELETE: remove/destroy a resource

URI

• Uniform Resource Identifier

In this context, the portion of the URL after the domain.

For the URL https://en.wikipedia.org/wiki/Uniform_Resource_Identifier, the URI would be /wiki/Uniform_Resource_Identifier.

Seven RESTful Routes

Create a table based on Task Manager:

• What a user wants
• Method (verb)
• URI
• Data Prep/Manipulation
• Redirect or Render
• Name of View

Not So RESTful routes

• In task manager, see if you can make a route localhost:3000/easter_egg that when you visit, has a picture of a moose on it.
