express-response-error

Send errors easily right from response object (eg. res.notFound('not found') -> 404 {"error":"not found"}).

Example

 var express = require('express');
 var expressResponseError = require('express-response-error');

 app = new express();
 
 var options = {};
 app.use(expressResponseError(options));

 app.get('/test/forbidden',(req,res,next)->
  res.forbidden('this resource is forbidden');
 )
 
 app.get('/test/custom',(req,res,next)->
  res.error('something bad has happened',444);
 )
 
 // handle formatting to suite your needs
 app.use((err,req,res,next)->
   res.status(err.code).send({error: err.message})
 )

 app.listen(process.env.PORT)

Options

• curlify - return curl for request
• logging - log every error payload with console.error
• stackLogging - include error stack in payload
• translation - translate error message (default null)
  • specify translate function accepting one argument
  • string i18n to use translation for i18n)

Translations with i18n

 var express = require('express');
 var expressResponseError = require('express-response-error');
 var i18n = require('i18n');

 i18n.configure({
    locales:['en','de']
 })

 app = new express();
 
 var options = {
    translate:'i18n'
 };
 app.use(expressResponseError(options));
 app.use(i18n.init)
 
 app.get('*',(req,res,next)->
  res.error('SOME_ERROR'); // this message gets translated with dictionary 
 )

 app.listen(process.env.PORT)

Debug

If you app is not running in production (process.env.NODE_ENV == 'production') or if you specify ?debug=1 in request stack is returned in response.
