HTTP Response Status Codes

You've probably heard not to hardcode numbers when writing code. Use constants instead. Let this be your guide when building RESTful APIs.

This is still a work in progress, and I intend to add code for multiple languages (the ones I know). If you want support for your language, feel free to add it.

How to generate Status Codes for your Language

• Copy the Javascript Code in http-response-codes.js and paste in your browser console

• Run the following code in the same console to generate for C#

  Object.keys(STATUS_CODES).map(key => `public const int ${key} = ${STATUS_CODES[key]};`).join('\n')

• Be sure to edit the code to adjust for your language :)

http-response-codes.js

const STATUS_CODES = {
    OK: 200, 
    CREATED: 201, 
    ACCEPTED: 202, 
    NON_AUTHORITATIVE_INFORMATION: 203, 
    NO_CONTENT: 204, 
    RESET_CONTENT: 205, 
    PARTIAL_CONTENT: 206,

203 is NON-AUTHORITATIVE INFORMATION.

How come you omitted 404?

You could also add 451: UNAVAILABLE FOR LEGAL REASONS

@shalvah Lmao ... 🤣 ... I wonder how I missed that

@shalvah, @allengblack ... fixed 😄

@mykeels how about turning this into a web page, so a user can easily go there, click on his language of choice and select download?
