Node.js express.js MongoDB JWT REST API - This is a basic API REST skeleton written on JavaScript using async/await. Great for building a starter web API for your front-end (Android, iOS, Vue, react, angular, or anything that can consume an API)

const UserAccess = require('../../../models/userAccess')
const { setUserInfo } = require('./setUserInfo')
const { generateToken } = require('./generateToken')
const {
  getIP,
  getBrowserInfo,
  getCountry,
  buildErrObject
} = require('../../../middleware/utils')

/**
 * Saves a new user access and then returns token
 * @param {Object} req - request object
 * @param {Object} user - user object
 */
const saveUserAccessAndReturnToken = (req = {}, user = {}) => {
  return new Promise((resolve, reject) => {
    const userAccess = new UserAccess({
      email: user.email,
      ip: getIP(req),
      browser: getBrowserInfo(req),
      country: getCountry(req)
    })
    userAccess.save(async (err) => {
      try {
        if (err) {

        const userInfo = await setUserInfo(user)

        resolve({
