middleware/auth.js========================
const { User } = require('../models/User')
let auth = (req, res, next) => {
let token = req.cookies.x_auth
User
.findByToken(token)
.then(user => {
if (!user) return res.json({ isAuth: false, error: true })
req.token = token
req.user = user
next()
})
.catch(err => {
throw err
})
}
module.exports = { auth }
- callback함수 없이 then과 catch를 사용
