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 uuid = require('uuid')
const User = require('../../../models/user')
const { buildErrObject } = require('../../../middleware/utils')

/**
 * Registers a new user in database
 * @param {Object} req - request object
 */
const registerUser = (req = {}) => {
  return new Promise((resolve, reject) => {
    const user = new User({
      name: req.name,
      email: req.email,
      password: req.password,
      verification: uuid.v4()
    })
    user.save((err, item) => {
      if (err) {
        reject(buildErrObject(422, err.message))
      }
      resolve(item)
    })
  })
}

module.exports = { registerUser }
