🗳️ Online Voting System

Overview

The Online Voting System is a full-stack web application designed to provide a secure, transparent, and efficient digital voting experience. The platform allows eligible voters to cast their votes online while ensuring that each voter can vote only once. It also provides an administrative dashboard for managing candidates, monitoring election activities, and viewing election results.

The system aims to reduce the complexity of traditional voting processes by digitizing voter registration, authentication, vote casting, and result management while maintaining security and integrity.

⚙️ Technical Approach

Frontend Architecture

The frontend is built using React.js and follows a component-based architecture. React Router manages navigation between pages, while Axios handles communication with backend APIs.

Key responsibilities include:

• User authentication
• Candidate display
• Vote submission
• Dashboard rendering
• Real-time UI updates

Backend Architecture

The backend is developed using Node.js and Express.js, following RESTful API principles.

The server handles:

• User authentication
• Candidate management
• Vote recording
• Election result processing
• Authorization and security
• Database operations

Database Design

MongoDB is used for storing application data through Mongoose schemas.

Users Collection

Stores:

• Name
• Aadhaar Number
• Email
• Password
• Voting Status
• User Role

Candidates Collection

Stores:

• Candidate Name
• Political Party / Group Name
• Candidate Image
• Vote Count

Authentication Flow

1. User registers with valid information.
2. Password is hashed using bcrypt.
3. User logs in successfully.
4. JWT token is generated by the server.
5. Token is stored on the client side.
6. Protected routes verify the token before granting access.
7. Eligible users can cast a vote only once.
