@mantris/appify/src/middlewares/normalizer.js

Very opinionated Node.js API boilerplate as module.

'use strict'

const { HttpError } = require('@mantris/commons')

const ERROR_CODE = 'INTERNAL_SERVER_ERROR'

/**
 * @returns {Function} Middleware.
 */
module.exports = () => {
  return (err, req, res, next) => {
    if (err instanceof HttpError) {
      return next(err)
    }

    return next(
      new HttpError.InternalServerError(ERROR_CODE, err.message, err.stack)
    )
  }
}
