How To Use 🤔?

1. First install truffle globally npm install truffle -g
2. Use truffle init to intiate truffle.
3. Now make changes in migration folder

   const demo = artifacts.require("demo");     
   module.exports = function(deployer){
       deployer.deploy(demo);              
   }

4. Add changes in truffle-config.js file.
   • Uncomment the development network and change port to 7545
   • Then add the line given below in the module.exports = section

     contracts_build_directory: "./frontend/public/contracts"

5. 👇 Add the Demo.sol file in contract folder. Here is the code 👇 (--You can skip this step--)

   // SPDX-License-Identifier: UNLICENCED
   pragma solidity ^0.8.7;
   contract demo{
       uint tomato;
   
       receive() external payable{}
   
   
   
       uint public numoffunder;    
       mapping (uint => address) private funders;
       
       function transfer_tocontract() external payable{
           funders[numoffunder] = msg.sender;
       }
       function withdraw(uint withdrawAmount) external payable{
           require(
               withdrawAmount <= 2000000000000000000,
               "Cannot withdraw more than 2 ether"
           );
           payable(msg.sender).transfer(withdrawAmount);
           
       }
   
   
       //setting and getting value of tomato
       function setvalue(uint value) public {
           tomato = value;
       }
   
       function getvalue() view public returns(uint){
           return tomato;
       }
   }   

6. Add the Frontend folder in this repo in the root directory of project.
7. Use npm install accordingly to install dependencies in frontend folder.
8. Now migrate the contract using truffle migrate --reset in frontend folder.
9. Finally Use npm start to see the working ✔✔
