connect-send-error

Adds the response.error() middleware to connect and connect-like http stacks.

res.error(code, message, statusCode);

// returns this to the user with the appropriate content-type and status code
{ "error": {
    "code": "S_MSG"
  , "message": "some message"
  }
}

If you supply a codes table it will use the message and status code from the table.

The default status code will be 400 (Bad Request).

The default error code will be UKN (Unknown Error).

Usage

'use strict';

var connect = require('connect')
  , app = connect()
  , send = require('connect-send-error')
  , codes
  ;

codes = {
  'BAD_ROBOT': { message: "You appear to be a spambot", statusCode: 400 }
, 'NOT_IMPL': { message: "Not Implemented", statusCode: 500 }
};

app
  .use(send.error({ codes: codes }))
  .use(function (req, res) {
    res.statusCode = 501;
    res.error('NOT_IMPL');
  })
  ;

module.exports = app;
