# Exercise 3: In Memory API
## Due Date: Tuesday January 19th 2021, 11:59 PM
## Objectives: To become familiar with creating custom endpoints for a REST API, how data is stored and modeled in a REST API,further practice with Javascript Array Methods, and how to properly structure an express API.
## Specifications/Requirements
We have provided you with a complete Express API application. You need to complete the code inside of 2 files: the `Contact.js` class inside of the `models` directory and `contacts.js` inside of `routes/api/v1`. We have provided comments at the top of both files with the requirements.
__Note: In order to run the application run ```npm install``` and then ```npm start``` in the top level directory of the exercise. To test your endpoints you will need the use of an external tool like Postman or the use of the Curl command line utility.__

/* In this file you will define all the routes for your api.
You will need to define the following routes:
1) /api/v1/contacts
This route will need to respond to 2 requests:
1) GET: it will respond with the serialized form of all the
contacts in your application and a response code of 200
2) POST: it will respond to a POST request that will generate a
new instance of a contact and add it to the in memory collection
and a response code 201
2) /api/v1/contacts/:id
This route will need to responde to 3 requests:
1) GET: it will respond with the serialized form of the requested
resource and a response code of 200. You will receive the :id from
the req.params.id property
2) PUT: it will update the resource with the information attached in
the req.query property. Note: query params end at the end of the route,
and all come after the ? character and are combined with a &.
For example, if you wanted to update the firstName and lastName properties
of the contact with an id of 3, the url would be (assuming your server is runing
on port 3000):
localhost:3000/api/v1/contacts/3?firstName=NewFirstName&lastName=NewLastName
Your route should respond with a 201 response code along with the updated
resource otherwise 404 with an error message of "unable to update resource".
3) DELETE: it will remove the contact from the collection with the matching id
in the request.params object and respond with a status code of 201 alone with
the deleted resource in the response. If the resource is not found the route should
respond with a 404 error and message "resource not found".
Hint: when sending your response you should follow the following examples:
res.status(404).json({error: 'Contact not found'})
res.status(200).json(contacts)
res.status(201).json(data)
