505 HTTP Version Not Supported

The server does not support the HTTP protocol version you are trying to use.

When and Why to Use It

Extremely rare. Throw this if your server strictly requires HTTP/2 or HTTP/3, and a client tries to connect with HTTP/1.0.

Usage Examples

Shokupan (Functional)

import { HttpException, get } from 'shokupan';

export const getResource = get('/resource', () => {
    throw new HttpException('HTTP Version Not Supported', 505);
});

Shokupan (Controller)

import { Controller, Get, HttpException } from 'shokupan';

@Controller('/api')
export class ExampleController {
    @Get('/resource')
    getResource() {
        throw new HttpException('HTTP Version Not Supported', 505);
    }
}

Express

import express from 'express';
const app = express();

app.get('/resource', (req, res) => {
    res.status(505).json({ error: 'HTTP Version Not Supported' });
});

Nest

import { Controller, Get, HttpException } from '@nestjs/common';

@Controller('api')
export class ExampleController {
  @Get('resource')
  getResource() {
    throw new HttpException('HTTP Version Not Supported', 505);
  }
}

Koa

import Koa from 'koa';
const app = new Koa();

app.use(async ctx => {
  if (ctx.path === '/resource' && ctx.method === 'GET') {
    ctx.status = 505;
    ctx.body = { error: 'HTTP Version Not Supported' };
  }
});
