이제 계약 소스인데 실제로 어떻게 배포 해야하는지 알아야 합니다.

배포에는 다양한 옵션이 있습니다.

계약 생성에 도움을 줄 수 잇는 명령어 도구인 트러플로 할 예정입니다

이제 새로운 프로젝트을 생성해서 만들어 볼려고 합니다. 프로젝트에서 파일 구조는 아래와 같습니다

Inbox.sol 파일 입니다

pragma solidity ^0.4.17;
// linter warnings (red underline) about pragma version can igonored!

// contract code will go here


contract Inbox {
    string public message;
    function Inbox(string initialMessage) public {
        message = initialMessage;
    }
    function setMessage(string newMessage) public {
        message = newMessage;
    }
}

complie.js 파일입니다

// compile code will go here
const path = require('path');
const fs = require('fs');
const solc = require('solc');


const inboxPath = path.resolve(__dirname, 'contracts', 'Inbox.sol');
const source = fs.readFileSync(inboxPath, 'utf8');

console.log(solc.compile(source, 1))

터미널창에서 node compile.js 파일 입력하면

아래와 같은 내용이 출력된 것을 확인 할 수 있습니다

    ':Inbox': {

객체에 대해서 설명하자면 객체 안에 계약 송이들이 있습니다. 계약은 여러가지 형태로 되어 있을 수 있습니다.

solidity compiler는 여러 계약이 한 번에 컴파일 될 수 있다는 가정하에 만들어졌습니다.

위에 코드같은 경우는 인박스 계약서만 있습니다. 하지만 동시에 통과시킨 다른 계약이 있다면 이 개체 안에서 키 값 쌍을 볼 수 있을 것에요

inferface 부분은 abi 는 계약 상에 존재하는 호출 될 수 있는 모든 함수를 나열합니다.

아래 그림은 테스트 하는 과정입니다.

1. 웹 3 인스턴스를 만들 때마다 즉시 우리가 만든 새 인스턴스를 구성해야 해요

특히 공급자라는 걸 설정해야 해요

공급자는 웹 3 라이브러리와 특정 이더리움 네트워크 간의 통신 계층을 간주될 수 있쬬

여기 공급자가 있죠 이건 통신 계층이에요

다른 네트워크에 연결하기 위해 사용된 모든 공급자는 동일한 메서드 세트를 갖고 잇어요

이런 다양한 방법으로 웹 3 라이브러리는 로컬 네트워크에 요청을 보내고 그 요청에 대한 응답을 받죠

이더리움을 시험하기 위해 위에 그림과 같은 주기를 반복 합니다
