Project Structure

The structure of the repository is designed to separate concerns and make the codebase more maintainable and scalable. Below is a detailed breakdown of each directory and its purpose:

Agora_backend/

├── models/                 # Mongoose models for MongoDB
├── routes/                 # Express route handlers
├── scripts/                # Scripts for deployment and other tasks
├── test/                   # Mocha tests for the backend
├── utils/                  # Utility functions
├── hardhat.config.js       # Hardhat configuration

Directories and Files

contracts/

Contains Solidity smart contracts that are deployed on the Ethereum blockchain. These contracts define the core logic and rules of the Agora platform.

• Purpose: This directory is used to store and manage the smart contracts used by the Agora platform.

models/

Houses the Mongoose models that interact with MongoDB. Each model represents a different collection in the database and defines the schema and methods for that collection.

• Purpose: This directory is used for defining data models that interact with the MongoDB database.

routes/

Contains the route handlers for the Express server. Each route file corresponds to a different endpoint or set of endpoints and defines the logic for handling requests.

• Purpose: This directory is used to define the API endpoints and their request handlers.

scripts/

Includes scripts for contract deployment, and other automated tasks related to the project.

• Purpose: This directory is used for storing scripts that automate various tasks, such as contract deployment.

test/

Contains test files for the proposal voting smart contract. These tests are written using Mocha and are used to ensure the correctness of the backend logic.

• Purpose: This directory is used for storing test cases that ensure the reliability and correctness of the smart contract logic.

hardhat.config.js

Configuration file for Hardhat, the Ethereum development environment. It includes settings and plugins required for compiling, deploying, and testing smart contracts. Currently this is using Ethereum Sepolia for deployment and testing; however, for production release it should be changed to point to Luniverse Mainnet.

• Purpose: This file configures Hardhat, specifying network settings, compiler settings, and plugins used for blockchain development.

index.js

The main entry point of the application. This file initializes the Express server and sets up the routes and middleware.

• Purpose: This file starts the server, sets up middleware, and initializes the API routes.
