Async/Await wrapper for express routes (to avoid try/catching every route)

asyncErrorHandler.js

// Adds a .catch to the express callback to handle errors that happen in async/await functions
// you should wrap every route with this handler
// ie: errorHandler((req, res) => res.send(JSON.stringify(res.locals.user)))
const errorHandler = fn => (req, res, next) => {
  Promise.resolve(fn(req, res, next))
    .catch(error => {
      if (process.NODE_ENV === 'development') console.log(require('util').inspect(error))
      next(error)
    })
}

module.exports = asyncErrorHandler
