express-error-middleware

Simple error handling middleware for express.js

Install

$ npm install --save express-error-middleware

Usage

Below is a example of usage. test/app.js also have a similar example.

var express = require('express');
var errorHandler = require('express-error-middleware');
 
var app = express()
 
// define your routes
 
app.use(errorHandler.NotFoundMiddleware); // if a request is not handled before this a NotFoundError will be sent into next
app.use(errorHandler.ErrorsMiddleware); // this will render an error page based on the error it gets.

NotFoundMiddleware

Creates a NotFoundError and passes it along.

ErrorsMiddleware

Renders a request based on the error. error.status will determine the status code of the HTTP request in addition to selecting the template. If error.status is not set, it will default to 500. The template rendering looks for error/<status-code>. Thus, if jade is the template engine an error with 403 as status code will use error/403.jade as a template.

ApiErrorsMiddleware

Creates a JSON-response with the error, works similar to ErrorsMiddleware in the way that error.status defines the HTTP status code.

CsrfErrorMiddleware

Helper for using csurf. It turns an error from csurf into something that ErrorsMiddleware and ApiErrorsMiddleware understands.
