(auth.js)

    const express = require("express");
    const passport = require("passport");

    const jwt = require("jsonwebtoken");
    const { User, Post, Comment, Image } = require("../models");
    const { isLoggedIn, isNotLoggedIn } = require("./middlewares");
    const { Op } = require("sequelize");

    const router = express.Router();

    router.get("/kakao", passport.authenticate("kakao"));

    router.get(
      "/kakao/callback",
      passport.authenticate("kakao", {
        session: false,
      }),
      (req, res, next) => {

you can use a string describing a time span

Example

import jwt from "jsonwebtoken"
let token = jwt.sign({ foo: "bar" }, "secret key", { expiresIn: "30m" })

reference

ms('2 days')  // 172800000
ms('1d')      // 86400000
ms('10h')     // 36000000
ms('2.5 hrs') // 9000000
ms('2h')      // 7200000
ms('1m')      // 60000
ms('5s')      // 5000
ms('1y')      // 31557600000
ms('100')     // 100
ms('-3 days') // -259200000
ms('-1h')     // -3600000
ms('-200')    // -200

This documentation will give you more information on strings describing a time span. https://github.com/vercel/ms/blob/master/readme.md

You can replace this

const token = jwt.sign({ id: snsId, provider }, "jwt-secret-key", {
    expiresIn: 60 * 60,
});

with this

const iat = Math.floor(Date.now() / 1000)
const exp = iat + 60 // seconds
const token = jwt.sign(
      {
        id: snsId,
        provider,
        iat,
        exp
      },
      'jwt-secret-key'
    )

var jwt = require('jsonwebtoken');
var token = jwt.sign({ foo: 'bar' }, 'secret key',{expiresIn: 1}); // 1 sec
console.log(token);
setTimeout(()=>{
  try {
  var decoded = jwt.verify(token, 'secret key');
  console.log(decoded)
} catch(err) {
  console.log('error',err)
}
},2000);
