如何使用 React web 应用程序部署智能合约？

Question

To deploy a smart contract I have so far used remix ide. But now I am in a need to create a website that allows to deploy smart contract just hitting a button? Can I do that?

// SPDX-License-Identifier: MIT
pragma solidity ^0.8.0;
interface AnotherContract {
    function walletOfOwner(address owner) external view returns (uint256[] memory);
}

contract Demo{
    uint public similarity;
    uint256 public hasRedPill;
    constructor(
    string memory _name,
    string memory _symbol,
    string memory _initBaseURI
  )  {
     
    // some code
  }
    function test() public view returns(uint256  ){
       AnotherContract anotherContract = AnotherContract(address(0x116486FD64Ba04F7B789278B239E2e5A1e2f7b39));
      return anotherContract.walletOfOwner(msg.sender).length;
    }
}

Let's say I want to deploy this demo contract using my react js web app. Here I have to first send the constructor parameters then deploy the contract. In return I need the byte code, abi and address of the contract.

Is there any way to do that? I have a sense that it is possible since remix ide also provides a ui to deploy the contract. I am new to this. Please help.

1. Set up Truffle

npm install -g truffle

2. Make an empty repository, cd into it, then

truffle init

3. Configure the Local network and the provider

In truffle.config.js , add the following snippet inside the module.exports:

module.exports = {
  networks: {
    development: {
     host: "127.0.0.1",
     port: 7545,
     network_id: "*",
    },
  },
  compilers: {
    solc: {
      version: "0.8.0",
      settings: {
       optimizer: {
         enabled: false,
         runs: 200
       }
      }
    }
  }
};

4. Now Compile smart Contracts

truffle compile

5. Migrate Smart Contracts

truffle migrate

That's it, it should create an ABI array and contract address in the .json file

The answer to your question is going to be a VERY long one. Sagar's suggestion is a good lead although there is a lot that needs to be covered here.

I would recommend you watch the crash course linked below to get you situated. This course will help you step by step and go into quite a bit of detail (which greatly helped me). I see you already have some backend knowledge so to cover the front end I would suggest you skip to lesson 10 where NextJS/React are covered.
