Mongo CRUD
Assignment 2

# The brief

This is the second of three take home assignments related to building a backend web service to support a simple class list application called cListR.

In the previous assignment you built the base for the cListR RESTful API using Node.js and the Express framework. For this assignment you will enhance that base application to use MongoDB for data persistance and add measures to sanitize incoming data.

# Core Requirements

1. Using the Express.js framework, the API will expose a full set of CRUD routes (six, including both put and patch) for each of two resources: students, and courses. All API resource paths must begin with /api.

2. Resource collections will be stored in MongoDB and accessed via Mongoose Model classes. The Model.schema for the resource objects will have the following properties.

# Student

Property	Type	Required	Max Length
firstName	String	true	64
lastName	String	true	64
nickName	String	false	64
email	String	true	512

# Course

Property	Type	Required	Max Length
code	String	true	16
title	String	true	255
description	String	false	2048
url	String	false	512
students	Array	false	n/a

3. The students property of the Course model should be an array of object ids referencing the Student model.

4. Each resource should have its own Router module.

5. Routes related to individual members of a resource collection should use a validation function which will return a properly formatted 404 response with an errors array for any invalid req.params.id value.

6. All client supplied data (i.e. the req.body object) should be sanitized before being stored in the database. This should include guarding against cross site scripting (XSS) and query injection attacks.

7. Ensure that you write clean and readable code. Pay attention to:

• no runtime errors
• consistent 2 space indentation
• logical grouping of related code
• semantically descriptive names for variables and functions
• well organized project folder structure
• properly formatted package.json file
  • correct project name
  • your author details

# Logistics

• Accept this GitHub Classroom assignment invitation.
• Clone the repo to your laptop.
• Build the project on your laptop.
• Test each route with Postman.
• Make git commits as you complete each requirement
• When everything is complete, push the final commit back up to GitHub and submit the GitHub repo's URL on Brightspace.
