🏗 Scaffold-ETH 2

web3Food

web3Food is a decentralized food ordering and management smart contract system built on the Ethereum blockchain. This project allows users to place food orders and enables the owner to manage these orders. It leverages smart contracts to handle food item listings, order processing, and status updates.

Features

• Add Food Items: The owner can add new food items to the system with details such as name, price, description, and image.
• Place Orders: Users can place orders by specifying the food item index and a table number, and pay for their orders in Ether.
• Manage Orders: The owner can mark orders as prepared once they are ready.
• View Orders: Display a list of orders with their details and current status.

Contract Functions

addFood

Adds a new food item to the system.

Parameters:

• string memory _name: Name of the food item.
• uint256 _price: Price of the food item in Wei.
• string memory _description: Description of the food item.
• string memory _image: URL of the food item's image.

getFood

Retrieves the details of a food item.

Parameters:

• uint256 _index: Index of the food item in the list.

Returns:

• food memory: Details of the food item.

buyFood

Allows users to place an order.

Parameters:

• uint256 _index: Index of the food item to order.
• string memory tableId: Table number for the order.

Requires:

• Sufficient funds to cover the food item's price.

prepareOrder

Marks an order as prepared.

Parameters:

• uint256 _index: Index of the order in the list.

Requires:

• Only the contract owner can call this function.

withdraw

Allows the owner to withdraw the Ether balance of the contract.

User Interface

The user interface provides the following features:

• Admin Panel: Allows the owner to view all orders, mark orders as prepared, and see the status of each order.
• Order List: Displays orders that are not yet prepared. If there are no unprepared orders, a message indicating "No Orders" is shown.

Setup

1. Deploy the Contract

   Deploy the web3Food smart contract to the Ethereum network.

2. Connect Your UI

   Integrate the contract functions into your frontend using a library like wagmi for Ethereum interaction.

3. Run the Application

   Start your frontend application and interact with the smart contract via the user interface.

Requirements

Before you begin, you need to install the following tools:

• Node (>= v18.17)
• Yarn (v1 or v2+)
• Git

Quickstart

To get started with Scaffold-ETH 2, follow the steps below:

1. Install dependencies if it was skipped in CLI:

cd mweb3-food
yarn install

2. Run a local network in the first terminal:

yarn chain

This command starts a local Ethereum network using Hardhat. The network runs on your local machine and can be used for testing and development. You can customize the network configuration in packages/hardhat/hardhat.config.ts.

3. On a second terminal, deploy the test contract:

yarn deploy

This command deploys a test smart contract to the local network. The contract is located in packages/hardhat/contracts and can be modified to suit your needs. The yarn deploy command uses the deploy script located in packages/hardhat/deploy to deploy the contract to the network. You can also customize the deploy script.

4. On a third terminal, start your NextJS app:

yarn start

Visit your app on: http://localhost:3000. You can interact with your smart contract using the Debug Contracts page. You can tweak the app config in packages/nextjs/scaffold.config.ts.

Run smart contract test with yarn hardhat:test

• Edit your smart contract YourContract.sol in packages/hardhat/contracts
• Edit your frontend homepage at packages/nextjs/app/page.tsx. For guidance on routing and configuring pages/layouts checkout the Next.js documentation.
• Edit your deployment scripts in packages/hardhat/deploy
