Student Management Web App

Description

This web application demonstrates CRUD (Create, Read, Update, Delete) operations using AWS DynamoDB for managing student records. The backend integrates AWS IAM for security and AWS CLI for DynamoDB operations. Users can add, fetch, update, and delete student information via a REST API.

Tech Stack

• Frontend: HTML, CSS, JavaScript
• Backend: Node.js, Express
• Database: AWS DynamoDB
• AWS SDK: aws-sdk for interacting with DynamoDB
• Authentication: AWS IAM for secure access

Prerequisites

• AWS account with DynamoDB and IAM access
• AWS CLI installed and configured with proper IAM roles and permissions
• Node.js installed
• npm install aws-sdk express body-parser for backend dependencies
• Basic understanding of AWS IAM, DynamoDB, and Node.js

How to Run the Project

1. Clone the repository
   Clone the repository to your local machine using:

   git clone <repository_url>

2. Install Dependencies
   Navigate to the project directory and install required dependencies:

   cd student-management-app
   npm install

3. Configure AWS CLI and IAM Roles

   • Set up AWS CLI with your credentials:

     aws configure

   • Ensure your IAM user has the necessary permissions to interact with DynamoDB

4. Set Up DynamoDB Table

   • Create a DynamoDB table named students with studentId as the partition key (String).
   • Ensure your IAM roles have sufficient permissions to perform CRUD operations on the table.

5. Backend Configuration

   • The backend code uses the aws-sdk to perform DynamoDB operations, so ensure that the IAM credentials are set up correctly and that the SDK is configured properly.

6. Run the Project
   Start the backend server:

   node app.js

7. Access the App
   Open a web browser and navigate to http://localhost:3000 to access the web app.

How to Use the App

• Create a Student: Send a POST request to /api/students with student data (e.g., name, age, grade).
• Read (Retrieve) Student: Send a GET request to /api/students/:id to fetch student details by ID.
• Update Student: Send a PUT request to /api/students/:id to update student information.
• Delete Student: Send a DELETE request to /api/students/:id to remove a student by ID.

Key Features

• Full CRUD operations on student data using AWS DynamoDB.
• Secure access to DynamoDB using AWS IAM roles and AWS CLI.
• Simple API with Express for handling HTTP requests and responses.
• Easy-to-use frontend for interacting with the API.
