Building a Full-Stack Decentralized Application (DApp) with Vite, React, and Solidity

Prerequisites

Before starting this tutorial, make sure you have the following:

• A working knowledge of building frontend UIs with React and CSS
• Familiarity with Tailwind CSS, Vite, VS Code, and npm
• Basic understanding of the Solidity language syntax
• Familiarity with the Ethereum ecosystem

Setting Up the Project

First, create a new folder for your project and open it in VS Code. Then, create two subfolders: client and smart_contract. Navigate to the client folder and run the following command to initialize a new Vite project:

npm init vite@latest

Follow the prompts to set up your project, choosing React as your framework and variant.

Building the Frontend

Next, install the required dependencies for your frontend, including React, Tailwind CSS, and ethers.js:

npm install react-icons ethers

Create a new folder called components inside the src folder, and add the following components:

• Navigation_bar.jsx
• Footer.jsx
• Loader.jsx
• Services.jsx
• Welcome.jsx
• Transactions.jsx

Each component should contain the following code, replacing Component_name with the actual name of the component:

import React from 'eact';

const Componentname = () => {
  return <div>
    Componentname
  </div>;
};

export default Componentname;

Create an index.js file to export all the components:

import Navigationbar from './Navigation_bar';
import Footer from './Footer';
import Loader from './Loader';
import Services from './Services';
import Welcome from './Welcome';
import Transactions from './Transactions';

export { Navigation_bar, Footer, Loader, Services, Welcome, Transactions };

Building the Smart Contract

Navigate to the smart_contract folder and run the following command to initialize a new Hardhat project:

npx hardhat

Follow the prompts to set up your project, choosing the Ropsten test network.

Create a new file called Transactions.sol and add the following code:

pragma solidity ^0.8.0;

contract Transactions {
  // Add your contract logic here
}

Compile and deploy your contract using the following commands:

npx hardhat compile
npx hardhat deploy --network ropsten

Testing and Deployment

To test your contract, navigate to the smart_contract folder and run the following command:

npx hardhat test --network ropsten

Once you’ve tested your contract, deploy it to the Ropsten test network using the following command:

npx hardhat deploy --network ropsten

Connecting to the Blockchain

To connect your frontend to the blockchain, create a new folder called context inside the src folder, and add a new file called TransactionContext.jsx. This file should contain the following code:

import React, { useState, useEffect } from 'eact';
import { ethers } from 'ethers';

const TransactionContext = React.createContext();

const TransactionProvider = ({ children }) => {
  const [account, setAccount] = useState('');
  const [chainId, setChainId] = useState('');
  const [contract, setContract] = useState(null);

  useEffect(() => {
    // Connect to the blockchain here
  }, []);

  return (
    <TransactionContext.Provider value={{ account, chainId, contract }}>
      {children}
    </TransactionContext.Provider>
  );
};

export { TransactionProvider, TransactionContext };
