Installation

Install from npm

npm install @js-thing/http-status-codes

---

Import it to your project

Use ES module import

import { 
    HttpInformationStatusCodes, 
    HttpSuccessStatusCodes,
    HttpRedirectionStatusCodes,
    HttpClientErrorStatusCodes,     
    HttpServerErrorStatusCodes,
    HttpStatusCodes,
} from '@js-thing/http-status-codes';

Or CommonJS Require

const { 
    HttpInformationStatusCodes, 
    HttpSuccessStatusCodes, 
    HttpRedirectionStatusCodes, 
    HttpClientErrorStatusCodes, 
    HttpServerErrorStatusCodes,
    HttpStatusCodes,
} = require('@js-thing/http-status-codes');

Usage

The HttpStatusCodes enum is the status code super set of HttpInformationStatusCodes, HttpSuccessStatusCodes, HttpRedirectionStatusCodes, HttpClientErrorStatusCodes and HttpServerErrorStatusCodes enums

// use the combined enum to access any status code
const code = HttpStatusCodes.Continue; // code = 100
const code = HttpStatusCodes.Ok; // code = 200
const code = HttpStatusCodes.Found; // code = 302
const code = HttpStatusCodes.BadRequest; // code = 400
const code = HttpStatusCodes.InternalServerError; // code = 500

// Or use the individual enum group
const code = HttpInformationStatusCodes.Continue; // code = 100
const code = HttpSuccessStatusCodes.Ok; // code = 200
const code = HttpRedirectionStatusCodes.Found; // code = 302
const code = HttpClientErrorStatusCodes.BadRequest; // code = 400
const code = HttpServerErrorStatusCodes.InternalServerError; // code = 500

Similarly for reason phrase

const {
    HttpInformationReasonPhrases,
    HttpSuccessReasonPhrases,
    HttpRedirectionReasonPhrases,
    HttpClientErrorReasonPhrases,
    HttpServerErrorReasonPhrases,
    HttpReasonPhrases
  } = require("@js-thing/http-status-codes");

// use the combined enum to access any reason rhrase
const phrase = HttpReasonPhrases.Continue; // phrase = "Continue"
const phrase = HttpReasonPhrases.Ok; // phrase = "OK"
const phrase = HttpReasonPhrases.Found; // phrase = "Found"
const phrase = HttpReasonPhrases.BadRequest; // phrase = "Bad Request"
const phrase = HttpReasonPhrases.InternalServerError; // phrase = "Internal Server Error"

// Or use the individual enum group
const phrase = HttpInformationReasonPhrases.Continue; // phrase = "Continue"
const phrase = HttpSuccessReasonPhrases.Ok; // phrase = "OK"
const phrase = HttpRedirectionReasonPhrases.Found; // phrase = "Found"
const phrase = HttpClientErrorReasonPhrases.BadRequest; // phrase = "Bad Request"
const phrase = HttpServerErrorReasonPhrases.InternalServerError; // phrase = "Internal Server Error"

Check status code, reason phrase defined in RFC

const {
  isSuccessStatusCode,
  isSuccessReasonPhrase,
  isSuccessStatus,
} = require("@js-thing/http-status-codes");

isSuccessStatusCode(200); // returns true
isSuccessStatusCode(250); // returns false as 250 is not defined in RFC
isSuccessReasonPhrase("OK"); // returns true
isSuccessReasonPhrase("ABC"); // returns false
// isSuccessStatus accepts both number or string and can check code or phrase
isSuccessStatus(200); // returns true
isSuccessStatus("OK"); // returns true

// similarly these methods are available for other status family as well

Check status code family

const {
  is1xxInformationStatusCode,
  is2xxSuccessStatusCode,
  is3xxRedirectionStatusCode,
  is4xxClientErrorStatusCode,
  is5xxServerErrorStatusCode,
} = require("@js-thing/http-status-codes");

is1xxInformationStatusCode(code); // returns true for code >= 100 && code <=199
is2xxSuccessStatusCode(code); // returns true for code >= 200 && code <=299
is3xxRedirectionStatusCode(code); // returns true for code >= 300 && code <=399
is4xxClientErrorStatusCode(code); // returns true for code >= 400 && code <=499
is5xxServerErrorStatusCode(code); // returns true for code >= 500 && code <=599

Get status code, reason phrase and complete status code with phrase

const {
  getStatusCode,
  getReasonPhrase,
  getCompositeStatus,
} = require("@js-thing/http-status-codes");

getStatusCode("OK"); // returns 200
//or pass an optional parameter to ignore the case of the status phrase
getStatusCode("ok", true); // returns 200
getStatusCode("abc"); // returns undefined

getReasonPhrase(200); // returns "OK"
getCompositeStatus(200); // returns "200 OK"
