Express-response-errors NPM

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.
