Provides the `HttpStatus` class for managing HTTP response status codes.
npm install @be/http-statusProvides the HttpStatus class for managing HTTP response status codes.
Version 1.0.2
This is a scoped package under the be namespace.
``
$ npm install --save @be/http-status
Include the be namespace when using this package.
`javascript`
const HttpStatus = require('@be/http-status')
There is a factory method for each HTTP status code. The following creates a 404 (Not Found) status.
`javascript
let status = HttpStatus.notFound()
console.log(status.toString())
// 404 (Not Found)
`
The status name is also set as a property with a true value on the created status instance. (The status name is the same as the factory method name.)
`javascript
console.log(status.notFound)
// true
console.log(status.ok)
// undefined
`
Each status can also be converted into an error object. The error object is an instance of the HttpError class, which is attached to the HttpStatus class returned by this module. The status.error method accepts util.format arguments.
`javascript
let docid = 'A12345'
let error = status.error('This document (%s) is not available.', docid)
console.error(error.toString())
// HttpError: 404 (Not Found) This document (A12345) is not available.
`
The status.error method also accepts an Error object. In that case, the message from the specified error is used.
`javascript`
let err = new Error('No such record exists.')
console.error(status.error(err).toString())
// HttpError: 404 (Not Found) No such record exists.
In all cases:
- A RangeError will be thrown if the status code is not in the 4xx or 5xx range of error codes.message
- The code and reason phrase is always added to the beginning of the error message.
- If the is not specified, the status class ('Client Error' or 'Server Error') is used instead.new HttpStatus.HttpError(status, message)
- Calling is the same as calling status.error(message).
The HttpStatus class is exported by the module. You can call this constructor directly instead of using the factory methods.
`javascript`
let conflict = new HttpStatus(409)
// Instead of HttpStatus.conflict()
Using the factory method is more readable and does not require the new keyword.
The following is the array of status codes along with the reason phrase (text) and the identifier (name) for each code.
