Course Enrollment System - MongoDB Schema

Overview

You're helping build the backend of a course enrollment platform. In this assignment, your task is to design a Mongoose schema to represent students, the courses they can enroll in, and related data validations.

You'll write the schema in a schema.js file inside the boilerplate project.

Schema Requirements

General Guidelines

• Use proper data types and Mongoose validators
• Ensure fields like email are unique
• Use embedded documents where appropriate
• Apply constraints like required, default, and min or max where it makes sense

  • Required: true
  • Purpose: Student’s full name

• email

How to Fork and Set Up Your Repository

1. Fork the Repository on StackBlitz

• You will be provided with a StackBlitz link for the assignment.
• Open the link in your browser and click on the Fork button in StackBlitz.
  This will create a copy of the repository in your StackBlitz account.

2. Clone the Repository to Your Personal GitHub

• After forking, you can download the project or push it directly to your personal GitHub repository:
  • Option 1: Download and Push
    1. Download the repository files from StackBlitz.
    2. Open your terminal/command prompt, navigate to the project folder, and run:

bash git init git remote add origin <your_github_repo_url>

   Replace <your_github_repo_url> with your personal GitHub repository URL.
3. Commit and push the files to your GitHub repository:

bash git add . git commit -m "Completed the assignment" git push -u origin main

• Option 2: Push Directly
  1. Use the Push to GitHub option in StackBlitz to directly connect and push the repository to your GitHub account.
