express-promises-middleware.js

const asyncMiddleware = promise => {
  return (req, res) => {
    promise(req)
    .then(data => {
      res.status(200).json({
        success: true,
        ...data
      })
    })
    .catch(e => {
      console.error(e)
      res.status(500).json({
        success: false,
        error: e.message
      })
    })
  }
}

const getUser = async req => {
  return {
    user: req.user,
    session: req.session
  }
}

const app = express()
app.get ('/api/user', asyncMiddleware(getUser))
