    http-errors

    NPM Version NPM Downloads Node.js Version Build Status Test Coverage

    Create HTTP errors for Express, Koa, Connect, etc. with ease.

    Install

    This is a Node.js module available through the npm registry. Installation is done using the npm install command:

    $ npm install http-errors

    Example

    var createError = require('http-errors')
    var express = require('express')
    var app = express()
     
    app.use(function (req, res, next) {
      if (!req.user) return next(createError(401, 'Please login to view this page.'))
      next()
    })

    API

    This is the current API, currently extracted from Koa and subject to change.

    All errors inherit from JavaScript Error and the exported createError.HttpError.

    Error Properties

    • expose - can be used to signal if message should be sent to the client, defaulting to false when status >= 500
    • headers - can be an object of header names to values to be sent to the client, defaulting to undefined. When defined, the key names should all be lower-cased
    • message - the traditional error message, which should be kept short and all single line
    • status - the status code of the error, mirroring statusCode for general compatibility
    • statusCode - the status code of the error, defaulting to 500

    createError([status], [message], [properties])

    var err = createError(404, 'This video does not exist!')
    • status: 500 - the status code as a number
    • message - the message of the error, defaulting to node's text for that status code.
    • properties - custom properties to attach to the object

    new createError[code || name]([msg]))

    var err = new createError.NotFound()
    • code - the status code as a number
    • name - the name of the error as a "bumpy case", i.e. NotFound or InternalServerError.
