계층분리

Controller

export class ResumeController {
  constructor(resumesService) {
    this.resumesService = resumesService;
  }

  // 생성
  createResume = async (req, res, next) => {
    const { userId } = req.user;
    const { title, content, status = "APPLY" } = req.body;
    console.log(userId);
    const createdResume = await this.resumesService.createResume(userId, title, content, status);
    return res.status(201).json({ message: "게시글 생성에 성공하였습니다" });
  };

Service

export class ResumesService {
  constructor(resumesRepository) {
    this.resumesRepository = resumesRepository;
  }

  // 생성
  createResume = async (userId, title, content) => {
    const status = "APPLY";
    // await new Promise((resolve) => setTimeout(resolve, 3000)); 슬랙 알람??
    const resume = await this.resumesRepository.createResume(userId, title, content, status);
    const Statuses = ["APPLY", "DROP", "PASS", "INTERVIEW1", "INTERVIEW2", "FINAL_PASS"];
    if (!Statuses.includes(status)) {
      throw new Error("이력서 상태가 이상합니다.");
    }
    // await sendTodayData(); 슬랙 알람??
    return resume;
  };

Repository

export class ResumesRepository {
  constructor(prisma) {
    this.prisma = prisma;
  }

  // 생성
  createResume = async (userId, title, content, status) => {
    const resume = await this.prisma.resumes.create({
      data: {
        userId: +userId,
        title,
        content,
        status,
      },
    });
    return resume;
  };

Router

import express from "express";
import { prisma } from "../model/index.js";
import authMiddleware from "../middlewares/auth.middleware.js";
import { ResumeController } from "../src/controllers/resumeController.js";
import { ResumesService } from "../src/services/resumesService.js";
import { ResumesRepository } from "../src/repositories/resumesRepository.js";
// import jwt from "jsonwebtoken";
// import bcrypt from "bcrypt";

const router = express.Router();

const resumesRepository = new ResumesRepository(prisma);
const resumesService = new ResumesService(resumesRepository);
// PostsController의 인스턴스를 생성합니다.
const resumesController = new ResumeController(resumesService);

// 이력서 생성 API
router.post("/resume", authMiddleware, resumesController.createResume);

기존에 router를 3계층 분리 하여 생성 코드만 가져와봤다.
이런식으로 각각에 계층에 맞게 코드를 작성하여 실행하면 된다.(근데 나도 아직 잘 모르겠따..!)
controller, service, repository의 각각 역할
