jwt vs refresh ans access tokens code example

Example: jwt refresh token

/**
@description for module commonjs
*/

// JWT MIDDLEWARE
const jwt = require('jsonwebtoken')
const { message } = require('../utils/util.message')
 
module.exports = (req, res, next) => {
  try {
    const tokenHeader = req.headers.authorization.split('Bearer ')[1]
    const decoded = jwt.verify(tokenHeader, process.env.ACCESS_TOKEN_SECRET)
    req.user = decoded
    next()
  } catch (err) {
    next(httpError(401))
  }
}
 
// ROUTE LOGIN
app.get('/protect', authJwt, (req, res) => {
  console.log(req.user)
  res.send('aim in proteced route')
})
 
app.post('/login', (req, res) => {
  const bodyPayload = {
    id: Date.now(),
    username: req.body.username
  }
  const token = signAccessToken(res, bodyPayload)
  return res.status(200).json(token)
})
 
app.post('/refresh-token', (req, res) => {
  const refreshToken = signRefreshToken(req)
  return res.status(200).json(refreshToken)
})
 
// JWT HELPER
const jwt = require('jsonwebtoken')
const { message } = require('../utils/util.message')
 
exports.signAccessToken = (res, payload) => {
  try {
    if (payload) {
      const accessToken = jwt.sign({ ...payload }, process.env.ACCESS_TOKEN_SECRET, { expiresIn: '1d' })
      const refreshToken = jwt.sign({ ...payload }, process.env.REFRESH_TOKEN_SECRET, { expiresIn: '90d' })
      res.cookie('refreshToken', `${refreshToken}`, { maxAge: 86400 * 90, httpOnly: true })
      return { accessToken, refreshToken }
    }
  } catch (err) {
    message({
      response: res,
      statusCode: 401,
      method: req.method,
      message: 'Unautorization'
    })
  }
}
