express-response-errors 
Collection of custom response errors and middleware for Express.
Install
npm i express-response-errors -S
Configure
Add middleware to your application bootstrap file:
const { responseErrorHandler } = require('express-response-errors');
app.use(responseErrorHandler);
Usage 1
Pass HttpError exception with required code and optional message to Express from route handler.
const { HttpError } = require('express-response-errors');
// Ex. with default status text
next(new HttpError(418));
// Ex. with custom message
next(new HttpError(418, 'I only brew tea'));
Usage 2
Pass a specific http exception with optional message to Express from route handler.
const { ImATeapotError } = require('express-response-errors');
// Ex. with default status text
next(new ImATeapotError());
// Ex. with custom status text
next(new ImATeapotError('I only brew tea'));
Errors passed to Express without a message defaults to HTTP standard status text.
Errors are handled by middleware which sends related error message and status as a HTTP response.
