Erros.js

Simple Express error handler

Installation

npm install erros

Usage

var app = require('express')();
var erros = require('erros');

// configure your app...

app.use(erros.handler()); // should be last in the middleware stack

Responds to content types:

• text/html
• text/plain
• application/json

Define your own view folder and view engine extension.

app.use(erros.handle({views: __dirname+'/views', view_ext: 'jade'}));

• views your views directory, default ./
• view_ext view engine extension, default jade

Accept: text/html will always attempt to respond with res.render.

Your error pages should be named 5xx.your-extension and 4xx.your-extension for Server and Client errors respectively.

Change the default Status code.

app.use(erros.handle({default_status: 200}));

Status code will be 200, unless your error has a status property defining another code. Eg. use of custom Error

function MyError(msg, status) {
  Error.captureStackTrace(this);
  this.message = msg;
  this.name = 'MyError';
  this.status = status;
}

MyError.prototype = Object.create(Error.prototype);
