Development-only error handler middleware
$ npm install errorhandler
var errorhandler = require('errorhandler')
Create new middleware to handle errors and respond with content negotiation. This middleware is only intended to be used in a development environment, as the full error stack traces will be sent back to the client when an error occurs.
var connect = require('connect') var errorhandler = require('errorhandler') var app = connect() if (process.env.NODE_ENV === 'development') { // only use in development app.use(errorhandler()) }
