http-codes

Map of HTTP status messages to codes — the inverse of Node's built-in STATUS_CODES.

Stays in sync with Node: when the runtime adds or renames a status, this package picks it up automatically.

npm install http-codes

import codes from 'http-codes'
// or
const codes = require('http-codes')

codes.OK          // 200
codes.NOT_FOUND   // 404
codes.IM_A_TEAPOT // 418

Why use this

• Ultra simple — one small module, zero dependencies
• Always current — derived from Node's built-in map at load time
• TypeScript types included

API

The module exports a plain object. Each key is the status message in SCREAMING_SNAKE_CASE; each value is the numeric code.

import codes from 'http-codes'

if (res.statusCode === codes.NOT_FOUND) {
  // …
}

Keys are normalized from Node's messages: apostrophes removed, hyphens and spaces become underscores, then uppercased ("Request Timeout" → REQUEST_TIMEOUT).

The exact set of keys depends on your Node version. Run npm test to print the current map.

Upgrading from 1.x

No code changes needed if you used require('http-codes') and property access — that is the entire 1.0.0 API and it is preserved in 2.0.0.

2.0.0 is a major release because of packaging (TypeScript, dist/, dual ESM/CJS, built-in types, tooling) and the long gap since 1.0.0 — not because the require() shape changed.
