http-status-codes

Constants enumerating the HTTP status codes. Based on the Java Apache HttpStatus API.

All status codes defined in RFC1945 (HTTP/1.0), RFC2616 (HTTP/1.1), RFC2518 (WebDAV), RFC6585 (Additional HTTP Status Codes), and RFC7538 (Permanent Redirect) are supported.

TypeScript or JavaScript. Completely library agnostic. No dependencies.

Installation

``console
npm install http-status-codes --save
`

Usage (express 4.x)

`typescript
import {
ReasonPhrases,
StatusCodes,
getReasonPhrase,
getStatusCode,
} from 'http-status-codes';

response
.status(StatusCodes.OK)
.send(ReasonPhrases.OK);

response
.status(StatusCodes.INTERNAL_SERVER_ERROR)
.send({
error: getReasonPhrase(StatusCodes.INTERNAL_SERVER_ERROR)
});

response
.status(getStatusCode('Internal Server Error'))
.send({
error: 'Internal Server Error'
});

Migrating from v1.x.x

http-status-codes v2 is mostly backwards compatible with v1. There is a single breaking change and two recommended changes.

#### [Breaking Change] 'Server Error'

The reason phrase for the status code 500 has been changed from "Server Error" to "Internal Server Error". This is the correct phrase according to RFC7231. If you are migrating from v1, and have code that relies on the result of getStatusText(500) or getReasonPhrase('Server Error'), then this could affect you.

#### [Non-breaking change] getStatusText renamed getReasonPhrase

The function getStatusText has been renamed to getReasonPhrase. The old function is still available, but may be deprecated in a future version. To fix this simply rename instances of getStatusText() to getReasonPhrase(). The function is otherwise the same as it was before.

#### [Non-breaking change] StatusCodes

In http-status-codes v1, Status Codes were exported directly from the top-level module. i.e. HttpStatus.OK. In v2 all Status Codes live under an object called StatusCodes. i.e. HttpStatus.StatusCodes.OK. We made this change to cater to TypeScript users who prefer a dedicated value with an enum type. The previous values are still exported, but we won't continue to update them. Please migrate if you're using the old-style imports.

Proposing a new status code

If you'd like to propose a new status code, feel free to update "codes.json" with the necessary
information and open a pull request. There is no need to modify source code or even this README.
This is done automatically by npm run update-codes.

In general, we try to include only codes that have an official RFC and have been approved, however
exceptions can be made if the code is already in widespread use in the wild.

Steps to build and publish

`shell
npm run update-codes
npm run test
npm run build
npm version [major | minor | patch]
npm publish
``

After releasing, please add release notes via GitHub Releases.
