Package description
The errorhandler npm package is an error handler middleware for use with Express.js applications. It provides full stack traces and error message responses for errors during development, and a minimal response not leaking internal information in production.
Development Error Handling
In a development environment, errorhandler can provide detailed stack traces and error messages to the console and the client, helping developers debug issues.
app.use(errorhandler({ log: errorNotification }))
function errorNotification(err, str, req) {
var title = 'Error in ' + req.method + ' ' + req.url;
console.error(title, str);
}Production Error Handling
In a production environment, errorhandler can be used to send a generic error message to the client, without leaking sensitive stack trace information.
if (process.env.NODE_ENV === 'production') {
app.use(errorhandler());
}This package is a drop-in replacement for Express's default error handler. It automatically catches errors from async routes and passes them to your error handlers. It does not provide the same level of detail for stack traces as errorhandler, but it is useful for handling errors in asynchronous code.
This is an error handler for use with Express.js applications, similar to errorhandler. It is designed to provide a more secure, production-ready error handling solution. It can be configured to hide or show stack traces and error details based on the environment.
Readme
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())
}
