Create HTTP errors for Express, Koa, Connect, etc. with ease.
## Install
This is a [Node.js](https://nodejs.org/en/) module available through the
[npm registry](https://www.npmjs.com/). Installation is done using the
[`npm install` command](https://docs.npmjs.com/getting-started/installing-npm-packages-locally):
```console
$ npm install http-errors
```
## Example
```js
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.
### 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])
Create a new error object with the given message `msg`.
The error object inherits from `createError.HttpError`.
```js
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
### createError([status], [error], [properties])
Extend the given `error` object with `createError.HttpError`
properties. This will not alter the inheritance of the given
`error` object, and the modified `error` object is the
return value.
<!-- eslint-disable no-redeclare -->
```js
fs.readFile('foo.txt', function (err, buf) {
if (err) {
if (err.code === 'ENOENT') {
var httpError = createError(404, err, { expose: false })
} else {
var httpError = createError(500, err)
}
}
})
```
- `status` - the status code as a number
- `error` - the error object to extend
- `properties` - custom properties to attach to the object
### createError.isHttpError(val)
Determine if the provided `val` is an `HttpError`. This will return `true`
if the error inherits from the `HttpError` constructor of this module or
matches the "duck type" for an error this module creates. All outputs from
the `createError` factory will return `true` for this function, including
if an non-`HttpError` was passed into the factory.
### new createError\[code || name\](\[msg]\))
Create a new error object with the given message `msg`.
The error object inherits from `createError.HttpError`.
```js
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`.
