안녕하세요 복습중인데 msw 404 (Not Found) 질문드립니다.

Question

// http.ts import { createMiddleware } from "@mswjs/http-middleware"; import cors from "cors"; import express from "express"; import { handlers } from "./handlers"; const app = express(); const port = 9090; app.use( cors({ origin: "http://localhost:3000", optionsSuccessStatus: 200, credentials: true, }) ); app.use(express.json()); app.use(createMiddleware(...handlers)); app.listen(port, () => console.log(`Mock server is ruuning on port: ${port}`)); // handlers.ts import { http, HttpResponse } from "msw"; const CalendarData = [ { id: 0, date: "2024-03-01", memo: [ { id: 0, text: "식사", }, { id: 1, text: "운동", }, ], }, { id: 1, date: "2024-03-02", memo: [ { id: 0, text: "연차", }, { id: 1, text: "회의", }, ], }, { id: 2, date: "2024-03-03", reservation: 0, canceled: 0, noShow: 0, memo: [], }, { id: 3, date: "2024-03-04", memo: [ { id: 0, text: "공부", }, { id: 1, text: "휴식", }, ], }, { id: 4, date: "2024-03-05", memo: [], }, { id: 30, date: "2024-03-31", memo: [ { id: 0, text: "파티", }, { id: 1, text: "운동", }, ], }, ]; export const handlers = [ http.get("http://localhost:3000/api/calendar", ({}) => { return HttpResponse.json(CalendarData); }), ]; // browser.ts import { setupWorker } from "msw/browser"; import { handlers } from "./handlers"; const worker = setupWorker(...handlers); export default worker; // MSWComponent.tsx "use client"; import { useEffect } from "react"; export const MSWComponent = () => { useEffect(() => { if (typeof window !== "undefined") { if (process.env.NEXT_PUBLIC_API_MOCKING === "enabled") { require("@/mocks/browser"); } } }, []); return null; }; // msw api 요청 함수 export async function getCalendarData() { const res = await fetch(`http://localhost:3000/api/calendar`, { next: { tags: ["calendar"], }, cache: "no-store", }); if (!res.ok) { throw new Error("Failed to fetch calendar data"); } return res.json(); } // layout.tsx import type { Metadata } from "next"; import { Inter } from "next/font/google"; import "./globals.css"; import PortalWrap from "@/components/PortalWrap/PortalWrap"; import Toast from "@/components/Toast/Toast"; import { MSWComponent } from "@/mocks/MSWComponent"; import SSRQueryClientProvider from "@/libs/ReactQuery/SSRQueryClientProvider"; const inter = Inter({ subsets: ["latin"] }); export const metadata: Metadata = { title: "Create Next App", description: "Generated by create next app", }; export default function RootLayout({ children, }: Readonly<{ children: React.ReactNode; }>) { return ( {children} ); } // .env NEXT_PUBLIC_API_MOCKING=enabled NEXT_PUBLIC_MODE=local // package.json { "name": "planner", "version": "0.1.0", "private": true, "scripts": { "dev": "next dev", "build": "next build", "start": "next start", "lint": "next lint", "mock": "npx tsx watch ./src/mocks/http.ts" }, "dependencies": { "@tanstack/react-query": "^5.14.6", "classnames": "^2.5.1", "date-fns": "^3.3.1", "next": "^14.0.3", "react": "^18", "react-dom": "^18", "react-icons": "^5.0.1", "react-transition-group": "^4.4.5", "sass": "^1.71.1", "zustand": "^4.5.2" }, "devDependencies": { "@mswjs/http-middleware": "^0.9.2", "@tanstack/react-query-devtools": "^5.25.0", "@types/cors": "^2.8.17", "@types/express": "^4.17.21", "@types/node": "^20.10.5", "@types/react": "^18", "@types/react-dom": "^18", "@types/react-transition-group": "^4.4.10", "autoprefixer": "^10.0.1", "cors": "^2.8.5", "eslint": "^8", "eslint-config-next": "14.1.2", "express": "^4.18.2", "msw": "^2.0.11", "postcss": "^8", "tailwindcss": "^3.3.0", "typescript": "^5" }, "msw": { "workerDirectory": "public" } } npm run mock 를 사용해서 터미널에 Mock server is ruuning on port: 9090 이 나오는것까지 확인되었는데 GET http://localhost:3000/api/calendar 404 (Not Found) 콘솔에 이렇게 오류가 나옵니다. 몇시간 동안 이것저것 수정해보고 했는데 어디서 잘못된건지 왜 요청을 못받아오는지 모르겠습니다ㅠ

export const handlers = [ http.get("/api/calendar", ({}) => { return HttpResponse.json(CalendarData); }), ]; msw에는 호스트를 적는 게 아닙니다. 그리고 fetch 요청도 localhost:9090 으로 하셔야 합니다.
