problem

insomnia에서 post요청으로 보낼때 계속 에러나는 현상이 있었다. 코드도 똑같이 복붙했는데 안되니 뭐지 했는데.

const express = require('express')
const app = express()
const port = 3000

const connect = require('./schemas/index');
connect();


const goodsRouter = require("./routers/goods");
app.use("/api", [goodsRouter]);

app.use(express.urlencoded({extended: false}))
app.use(express.json())
app.use(express.static('public'));

const express = require('express')
const app = express()
const port = 3000

const connect = require('./schemas/index');
connect();
app.use(express.json())//이거뭐냐 이거 위치 위로 하니까 실행 됨

const goodsRouter = require("./routers/goods");
app.use("/api", [goodsRouter]);

app.use(express.urlencoded({extended: false}))
app.use(express.static('public'));

app.use(express.json())

이 미들웨어 코드를 위로 옮기니 실행 되었다.
아직 미들웨어 라는 정의도 쉽게 가닥이 잡히지 않는다. 한번 쭈욱 강의를 듣고 다시 들으면서 개념을 정리할 필요가 있어 보인다.
