Node Assessment

Setup

Run npm install to install dependencies.
Create a file called server.js. All of your server code and endpoints will be in this file.
Create a file called usersCtrl.js. In this file you will write all of the functions for your endpoints.
- Require the userData.json file in the usersCtrl.js file.
- Don't forget to export the functions that you create in the usersCtrl.js file.
Look at the userData.json file to get familiar with the data you will be using.

NOTE: You must use port 3000 during this assessment.

Import Postman tests

A file named node_assessment.postman_collection.json is inside the postman_testing folder. We will import this file in postman.

Open Postman.
In the top left corner, click on the Import button.
Make sure that Import File is selected / underlined, then click on Choose Files.
- You will need to select the node_assessment.postman_collection.json file (located in the postman_testing folder of this repo).

Running individual tests

As you create each endpoint, you can (and should) test the endpoint.
- Click on Collections on the left panel.
- Expand the collection of tests by clicking on the node_assessment collection.
NOTE: Each test name has a number after it that corresponds to a specific endpoint, which are numbered in the instructions. Most of the endpoints have multiple corresponding tests.
- Click on the test you want to run. Click on the blue Send button. The tests will automatically run when you send the request.
- Select Tests to see what tests passed/failed.
NOTE: You need to be running nodemon in order to successfully run the Postman tests.

IMPORTANT: The Postman tests manipulate some of the user data. Before you run the Postman tests, you should restart nodemon. You can do this in the terminal while nodemon is running by typing rs and then pressing enter.

Endpoints

Reminder: You must use port 3000 for this assessment.

Write your endpoints in server.js.

'GET' /api/users

Respond with the entire users array, with status 200.

This endpoint can be called with one of these queries, which you should be prepared to address:
- age: Return all users who have an age less than this age.
- lastname: Return all users whose last name matches.
- email: Return all users whose email matches.
- favorites: Return all users who have this favorite in their array of favorites.
  - Example request URL: localhost:3000/api/users?favorites=angular
'GET' /api/users/ + userId

The tests will send a GET request with the userId as a parameter to this endpoint. Remember, request params will come as strings. If the user is found, respond with status 200 and send that user's object.

If no user was found, respond with a status of 404 and null.

NOTE: You will need to use .json() instead of .send() when sending just null.
'GET' /api/admins

Respond with status 200, and an array of all users who are admins.
'GET' /api/nonadmins

Respond with status 200, and an array of all non-admin users.
'GET' /api/user_type/ + userType

Respond with status 200, and an array of all users that match the userType parameter.
'PUT' /api/users/ + userId

A user's information will be sent in the request body. It will contain the same type of user information container in the other user objects. You should update the user object that has an ID matching the userId parameter.

Return with status 200, and the entire array of user objects after you have updated the correct user object.
'POST' /api/users

A user's information will be sent in the request body. It will contain the same type of user information contained in the other user objects, except for the ID. You will need to add an ID to this user object before adding it to the users array.

The user IDs are sequential. If the last user object had an ID of 100, the new user object should have an ID of 101 and the next user object added should have an ID of 102, etc. The Postman tests will add multiple user objects and check the IDs.

You should return status 200 along with the entire array of user objects after the new user object has been added.
'DELETE' /api/users/ + userId

You should remove the user with an ID matching the userId parameter. Return status 200 and the array of user objects after the correct user object has been removed from the array.

Running the test collection

To pass the assessment, you need to run the collection and have all tests pass

Select Collections on the left panel of Postman (next to History).
Next to the node_assessment collection, click on the right arrow.
Select the blue Run button. This will open up the collection runner.
When you are ready to run the tests, select the blue Start Test button at the bottom. When all tests have passed, show your mentor.

NOTE: You need to be running nodemon in order to successfully run the Postman tests.

IMPORTANT: The Postman tests manipulate some of the user data. Before you run the Postman tests, you should restart nodemon. You can do this in the terminal while nodemon is running by typing rs and then pressing enter.
